operating this tractor. Failure to observe the following safety instructions could result in serious
injury or death.

1. GENERAL OPERATION
•

Read, understand, and follow all instructions in
the operator’s manual and on the machine
before starting. Keep this manual in a safe
place for future and regular reference.

•

Only allow responsible individuals familiar with
the instructions to operate the machine. Know
controls and how to stop the machine quickly.

•

Pay special attention to the warning and
caution labels affixed to the tractor.

•

Keep all safety decals clean and readable.
Replace any missing, illegible, or damaged
safety decals.

•

Use the handholds and step plates when
getting on and off the tractor to help prevent
accidental falls. Keep the steps and running
boards clear of mud and debris.

•

Before driving the tractor in reverse, check to
see that there are no people or obstacles
around.

•

Watch where you are going at all times. Watch
for and avoid all obstacles. Be alert at row
ends, near trees and other obstructions.

•

Never operate the machine while under the
influence of alcohol or drugs, or while fatigued.

•

When working in cooperation with others, let
them know in advance what you are doing.

•

Always sit in the tractor seat when starting the
engine or operating controls. Do not start the
engine or operate controls while standing
beside the tractor.

•

Do not allow anyone but the operator to ride on
the tractor unless a passenger seat is fitted.
Keep bystanders away from the tractor during
operation.

•

Never leave a running machine unattended.
Always engage the parking brake, lower implements to the ground, stop the engine and
remove the key before dismounting.

•

Do not modify or alter, or permit anyone else to
modify or alter, any tractor components or any
tractor functions.

•

Before starting the engine, sit in the seat,
disengage the clutch, and place the shift levers
in the neutral position.

•

Use the ROPS (Roll Over Protective Structure)
and seat belt for safe operation. Overturning
the tractor without a ROPS, or with a ROPS
and the seat belt unfastened, can result in
injury or death.

•

Always use the seat belt when the tractor is
equipped with a ROPS. Never us the seat belt
when the tractor is not equipped with a ROPS.

•

Whenever possible, adjust the rear wheels to
their maximum tread width to improve stability
of the tractor during operation.

•

Engage the parking brake, place the position
control lever in the down position, and place the
transmission levers in neutral before starting
the tractor.

•

Avoid accidental contact with control pedals
while the engine is running, as this can cause
unexpected movement of the tractor.

•

Shut off the engine and PTO, and engage the
parking brake before getting off the tractor.

•

Never try to get on or off a moving tractor.

•

Never park the tractor on a steep incline.

•

Do not run the engine in an enclosed building
without adequate ventilation. Exhaust fumes
can cause death.

•

Pull only from the drawbar. Make certain the
drawbar pin is locked in place. Pulling from the
rear axle of the tractor or any point above the
axle could cause the tractor to overturn.

•

Maintain the weight balance of the tractor.
Install front end weights to counterbalance
heavy implements attached to the three point
hitch. Do not operate the tractor with a light
front end.

•

Check all connections, and tighten if necessary,
before starting the engine or pressurizing lines.

•

Do not leave equipment in the raised position
when the vehicle is stopped or unattended.

•

Use only accessories approved for this
machine by the manufacturer. Read, understand and follow all instructions provided with
the approved accessory. Know your equipment
and its limitations.

•

Use the 3-point hitch only with equipment
designed for 3-point hitch usage.

•

Do not operate near embankments, ditches,
holes, or other terrain features which may collapse under the tractor’s weight. The tractor
could suddenly turn over if a wheel goes over
the edge of a cliff or ditch, or if an edge caves in.

•

Driving forward out of a ditch or mired condition, or up a steep slope, increases the risk of
the tractor flipping over backward. Use reverse
to free the tractor in these situations.

•

Check overhead clearance carefully before
driving under power lines, wires, bridges or low
hanging tree branches, before entering or
leaving buildings, or in any other situation
where the operator and/or roll bar may be
struck, which could result in serious injury.

•

Remember that your tractor, if abused or incorrectly used, can be dangerous and become a
hazard both to the operator and to bystanders.
Do not overload, or operate with attached
equipment which is unsafe, not designed for
the particular task, or is poorly maintained.

•

Lock the brake pedals together when traveling
at road speeds. Brake both wheels simultaneously when making an emergency stop.
Uneven braking at road speeds could cause
the tractor to tip over.

•

Watch for traffic when operating near or
crossing roadways. If local laws permit road
travel, use the headlights, flashing hazard lights
and SMV signs when traveling on public
roadways.

•

Do not engage the differential lock while
traveling at road speeds. Difficulty steering
could cause you to lose control of the tractor.
Avoid sudden motions of the steering wheel as
they can lead to a dangerous loss of stability.
The risk is especially great when the tractor is
traveling at road speeds.

•

Always slow the tractor down before turning.
Turning at high speed may tip the tractor over.

•

To avoid upsets, drive the tractor with care and
at a safe speed. Use extra caution when
operating over rough ground, when crossing
ditches or slopes, and when turning corners.

•

Wear sturdy work shoes. Never operate the
tractor in bare feet, sandals, or sneakers.

•

Do not wear loose fitting clothes or jewelry.
They can be caught in moving parts.

•

Keep all movement on the slopes slow and
gradual. Do not make sudden changes in
speed or direction. Rapid engagement or
braking could cause the front of the machine to
lift and rapidly flip over backwards which could
cause serious injury.

•

Avoid starting or stopping on a slope. If tires
lose traction, disengage the PTO and proceed
slowly straight down the slope.

DO NOT:

•

When towing equipment, use safety chains and
place an SMV emblem on the equipment.

•

Do not turn on slopes unless necessary; then,
turn slowly and gradually downhill, if possible.

•

Any towed vehicle with a total weight exceeding
that of the tractor should be equipped with its
own braking system that is operational from the
tractor seat.

•

Never "free-wheel". Disengaging the clutch or
shifting into neutral while descending a slope
could lead to a loss of control.

3. CHILDREN
2. SLOPE OPERATION
Slopes are a major factor related to loss of control
and tip-over accidents which can result in severe
injury or death. All slopes require extra caution. If
you cannot back up the slope or if you feel uneasy
on it, do not operate this unit on that area or serious
injury could result.
DO:

•

Tragic accidents can occur if the operator is not
alert to the presence of children. Children are
often attracted to the machine. Never assume
children will remain where you last saw them.

•

Keep children out of the operating area and in
watchful care of an adult other than the
operator.

•

Be alert and turn machine off if children enter
the area.

•

Before and when backing, look behind and
down for small children.

•

Operate up and down slopes, not across.

•

Remove obstacles such as rocks, limbs, etc.

•

Watch for holes, ruts or bumps. Uneven terrain
could overturn the machine. Tall grass can hide
such obstacles.

•

Never carry children. They may fall off and be
seriously injured or interfere with safe machine
operation.

•

Place the transmission in the low range. when
climbing or descending slopes. Always keep
machine in gear when going down slopes to
take advantage of engine braking action.

•

Never allow children to operate the machine.

•

Use extra care when approaching blind corners, shrubs, trees or other objects that may
obscure your vision of a child or other hazard.

•

Remove key when machine is unattended to
prevent unauthorized operation.

•

Follow the manufacturers recommendations for
counterweights to improve stability.

4. OPERATING THE PTO
•

Disengage the PTO, stop the engine, and wait
until all moving components have completely
stopped before dismounting the tractor and
connecting, disconnecting, adjusting, cleaning,
or servicing any PTO driven equipment.

•

Do not wear loose fitting clothing when
operating the PTO or when near rotating
equipment.

•

Keep the PTO shaft cover in place at all times.
Replace the PTO shaft cap when the shaft is
not in use.

•

When operating stationary PTO driven equipment, always apply the tractor parking brake
and place chocks behind and in front of the rear
wheels. Stay clear of all rotating parts.

•

Replace fuel cap securely and wipe off any
spilled fuel before starting the engine as it may
cause a fire or explosion.

•

Do not smoke when working around the battery
or when refueling. Keep all sparks and flames
away from the battery and fuel tank. The
battery presents an explosive hazard because
it gives off hydrogen and oxygen... especially
when recharging.

•

Never store the fuel container or machine
inside where there is an open flame or spark,
such as a gas hot water heater, space heater
or furnace.

•

The cooling system is under pressure. Never
remove the radiator cap when the system is
hot. Slowly turn the cap the to the first stop to
release pressure before removing the cap. If
the tractor has a coolant recovery tank, add
coolant there instead of to the radiator.

•

Escaping hydraulic fluid under pressure can
penetrate the skin. If fluid is injected into the
skin, seek immediate medical attention. Do not
use your hand to check for leaks. Use a piece
of cardboard or paper.

5. SAFETY FRAME (ROPS)
Your tractor is equipped with a rollover protective
structure (ROPS) which must be maintained in a
fully functional condition. Use care when driving
through doorways or spaces with a low overhead.
•

Never modify the ROPS in any way.

•

Never attempt to straighten or reweld any part
of the main frame or retaining brackets that
have been damaged. Doing so may weaken
the structure and endanger your safety.

•

Never secure any parts on the main frame or
attach the safety frame with anything other than
the special fasteners specified.

•

Never attach ropes, chains, or cables to the
ROPS for pulling purposes.

•

Although the ROPS provides you the maximum
protection possible, never take unnecessary risks.

6. SERVICE
•

Use extreme care in handling fuels. They are
extremely flammable and the vapors are
explosive. Use only an approved container.

•

Never remove fuel cap or add fuel with the
engine running.
8

•

Engine components become hot during
operation and can cause a burn. Allow to cool
down before touching.

•

Before "jump starting" a dead battery, read and
follow all of the instructions.

•

Do not attempt to mount a tire on the rim. This
should be done by a qualified person with
proper equipment.

•

Always maintain the correct tire pressure. Do
not inflate tires above the recommended
pressure shown in the operator’s manual.

•

Securely support the tractor when changing
wheels or the wheel tread width.

•

Make sure that wheel bolts
tightened to the specified torque.

•

To avoid sparks from arcing, always disconnect the battery’s negative cable first and
connect it last.

have

•

Disconnect negative cable from battery before
working on or near electrical components.

•

To reduce fire hazard, keep the tractor free of
any debris build-up. Clean up oil or fuel spillage.

•

Before cleaning, repairing or inspecting, make
certain all moving parts have stopped. Keep all
nuts, bolts and screws tight to be sure the
equipment is in safe working condition.

•

Never tamper with safety devices. Check their
proper operation regularly.

•

Check brake operation frequently. Adjust and
service as required.

•

Observe proper disposal laws and regulations.
Improper disposal of fluids and materials can
harm the environment and the ecology.

•

Prior to disposal, determine the proper method
to dispose of waste from your local
Environmental Protection Agency. Recycling
centers are established to properly dispose of
materials in an environmentally safe fashion.

•

Use proper containers when draining fluids. Do
not use food or beverage containers that may
mislead someone into drinking from them.
Properly dispose of the containers immediately
following the draining of fluids.

•

DO NOT pour oil or other fluids into the ground,
down a drain or into a stream, pond, lake or
other body of water. Observe Environmental
Protection Agency regulations when disposing
of oil, fuel, coolant, brake fluid, filters, batteries,
tires and other harmful waste.

•

We do not recommend the use of a pressure
washer or garden hose to clean your unit. They
may cause damage to electrical components;
spindles; pulleys; bearings; or the engine. The
use of water will result in shortened life and
reduce serviceability.

Figure 13
E. Hi-Lo Range Shift Lever

IMPORTANT: Do not hold the lever in the "Pull" or
"Push" position once the remote cylinder has reached
the end of its stroke. Doing so will force oil through
the relief valve, and over a prolonged period cause
the hydraulic oil to overheat.

WARNING: Never shift the Hi-Lo range
shift lever without first disengaging the
tractor’s clutch by depressing the clutch
pedal. Failure to do so will result in
severe damage to the transmission.

WARNING: When operating with the
differential lock engaged, the tractor will
be difficult to steer. To prevent loss of
control of the tractor, do not drive the
tractor on roadways or at speeds above 5
MPH with the differential lock engaged.

Front Wheel Drive Lever
The front wheel drive lever is located in the
floorboard, below and to the left of the seat.
Use the front wheel mechanism only when additional
traction is needed to drive the tractor. For example:
when operating ground engaging equipment such as
a front end loader; when climbing slopes; or when
operating in wet, sandy or loose soil conditions.
•

•

To engage the front wheel drive mechanism,
depress the clutch pedal and push the front
wheel drive lever downward. See Figure 15.
To disengage the front wheel drive, depress the
clutch pedal and pull the lever upward.

•

To engage the differential lock, lightly step on the
differential lock pedal with your heel.

•

To disengage, simple release the pedal.

Hydraulic Control Levers
The hydraulic control levers, consisting of the position
control and draft control levers, are located on the
right fender. See Figure 17.

Differential Lock Pedal
Located at the rear of the right floor board, the differential lock is used to gain additional traction when
operating the tractor on wet or loose soil. When the
pedal is depressed the rear wheels of the tractor are
prevented from rotating independently of one another.
See Figure 16.

Use these control levers to control the working depth
and pull of implements attached to the three point
hitch as follows:

DIFFERENTIAL
LOCK PEDAL

Figure 16

•

Using Position Control — This will control the
working depth of 3-point implements regardless
of the amount of pull required. Push the draft
control lever forward to the lowest position and
set the implement working depth by moving the
position control lever to the desired position.

•

Using Draft Control — This will control the pull of
the 3-point implement. As the pull on the 3-point
hitch changes due to various soil conditions, the
draft control system automatically responds to
these changes by either raising or lowering the
implement slightly to maintain a constant pull.
Push the position control lever forward to the
lowest position and set the implement pull by
moving the draft control lever to the desired
setting.

•

Using Mixed Control — In draft control, when draft
decreases, the implement automatically lowers to
increase draft. However, the implement sometimes lowers too much. To limit the degree the
implement can be lowered, set the position control
lever at the lowest working depth desired for the
implement; then lower the draft control lever to the
point where the implement is at the desired depth.
This stops the implement from going too deep and
also controls the pull to prevent loss of traction and
ground speed.

Brake Pedal Lock
The brake pedal lock is located on the right brake
pedal. Flip the lock counterclockwise so it engages
the bracket on the left brake pedal to interlock both
brake pedals. See Figure 18.

SECTION 2: OPERATION
ROLLOVER PROTECTIVE STRUCTURE (ROPS)

FUELING THE TRACTOR

This tractor is equipped with a foldable Rollover
Protection Structure (ROPS) and seat belts. When
used together they are effective in reducing injuries to
the operator in the event of an accidental tractor
rollover. The safety provided by the ROPS is
minimized if the seat belt is not properly adjusted
AND buckled.
WARNING: Always wear the seat belt
when operating the tractor equipped with
a ROPS. However, if the ROPS is in the
folded position or has been re-moved, the
seat belt must not be used.

Fill the fuel tank with only clean, fresh, diesel fuel. To
ensure the freshness of the fuel, purchase fuel in a
quantity that can be used within 30 days.
NOTE: DO NOT USE KEROSENE OR GASOLINE in
your diesel engine. Damage to the engine will occur.
Generally a good grade Number Two Diesel Fuel
should be used in your diesel engine. However, in
extremely cold temperatures a quality Number One
Diesel Fuel, or a blend of Number One and Number
Two Diesel fuels should be used. In most areas,
diesel fuel is properly blended for seasonal use as
ambient temperatures change. Therefore, it is
important to monitor fuel purchases so that seasonal
grade fuels are not carried over after the average
ambient temperature has changed.

Use the following guidelines when using a tractor
equipped with a ROPS:
•

•

Be aware of overhead clearances in the area of
operation. Check for clearance of door (or gate)
openings and other overhead objects such as
utility lines and tree branches. Overhead objects
could catch the ROPS and upset the tractor.

WARNING: Never fill the fuel tank to the
top of the filler neck. Expansion could
result in overflow through the vents in
the cap.

Do not modify the ROPS by drilling holes for, or
welding accessories to the structure.

•

Do not smoke while refueling the tractor.

•

Do not use the ROPS to pull objects with the
tractor. Use ONLY the tractor drawbar for pulling.

•

Do not fill the fuel tank when the engine is
running or while the engine is hot.

•

In the event of an accident, have the ROPS
carefully inspected and, if necessary, replaced by
your Cub Cadet dealer. Do not attempt to repair
the ROPS.

•

The fuel fill cap is located beneath the small
access door in the rearward end of the hood.
Press downward on the rear of the door to open.
See Figure 21.

PRE-STARTING CHECKS
Perform the following checks every day before starting and operating the tractor.

ACCESS
DOOR

•

Check the air pressures and general condition of
the tires.

•

Check under the tractor for any indications of oil
or water leakage.

•

Check that all lamps and lights work properly.

•

Walk around the tractor and inspect for loose
fasteners.

•

Check the transmission oil level.

•

Check the engine oil level.

•

Check the engine coolant level.

•

Check that the air cleaner is free of obstructions
and excessive dirt.

•

Check the fuel supply.

IMPORTANT: Use of a strainer when refueling is recommended to prevent impurities from entering the
fuel system and causing contamination of the injection pump.

•

Check operation of the clutch and brake pedals.

•

Check operation of the parking brake.

FUEL CAP

Figure 21

Unscrew the fuel cap and fill tank from an
approved container. Do not fill the fuel tank to
capacity. Allow room for expansion.

•

Tighten the fuel cap securely, and immediately
wipe up any spilled fuel.

•

To minimize condensation, keep the fuel tank as
full as possible without filling to capacity. It is a
good practice to fill the fuel tank at the end of the
day to reduce overnight condensation.

•

STARTING THE ENGINE
WARNING: Always sit in the operator’s
seat when starting the tractor, Never
attempt to start the engine while standing
beside the tractor.
WARNING: Never use a starting fluid,
such as ether, as a starting aid. Using a
starting fluid could cause severe engine
damage or a fire, and will void the engine
warranty.

Do not allow the fuel tank to run dry. Running out
of fuel requires bleeding air and priming the fuel
system.
WARNING: Fuel in the engine injection
system is under high pressure. If not a
qualified mechanic, do not attempt to
service the fuel injection system. Do not
use your hand to check for leaks.

•

Sit in the operator’s seat, adjust the seat position
(see ADJUSTMENTS), and fasten the seat belt
(only if a ROPS is installed and in the up
position).

•

Engage the parking brake. See Figure 22.

NEW TRACTOR BREAK-IN PROCEDURES
A new tractor is built with high tolerance, well fitted
components, but various parts require a break-in
period before being subjected to severe work loads.
The manner in which the tractor is handled during the
"break-in" period greatly affects the life of the tractor.
Therefore, to obtain the maximum performance and
longest service life from the tractor, it is very
important to properly break-in the tractor. Care should
be taken during the first 100 hours of operation to
operate the tractor at slower speeds and to avoid
excessive work loads. In handling a new tractor the
following precautions should be observed.
•

Do not operate the tractor at full speed for the
first 100 hours.

•

Do not start quickly or apply the brakes suddenly.

•

Never operate a new engine immediately under
full load. Allow the engine to warm up.

•

Avoid operating the engine for prolonged periods
at either high or low speeds with no load.

•

Use the transmission’s middle (or low) speed
range for heavy loads to avoid lugging down the
engine due to overload.

•

Closely monitor the engine oil and coolant levels,
and keep filled to the recommended levels.

•

As parts "break-in", minute particles of material
may break away, and could cause wear to the
component. Therefore, it is very important to
perform all break-in maintenance procedures
found in the MAINTENANCE section.

Slowly release the clutch pedal to start the tractor
moving.

•
•

If leaving the tractor, turn the ignition key to the
OFF position and remove the key.
If parking on an incline, chock the wheels to
prevent accidental rolling of the tractor.

•

Prior to going downhill, reduce the engine speed
and shift the transmission into a lower gear to
take advantage of the braking action of the
engine.

•

Before operating the tractor on a slope, walk the
slope to look for possible hazards such as rocks,
mounds, stumps, or surface irregularities which
could cause the tractor to be upset.

•

Back the tractor with attachment up the steepest
portion of each slope you intend to work. If the
tractor cannot negotiate the slope in reverse, the
slope is too steep to be worked.

•

Avoid turns when driving on a slope. If a turn
must be made, turn down the slope. Turning up a
slope greatly increases the chance of a roll over.

•

Avoid stopping when driving up a slope. If it is
necessary to stop while driving up a slope, start
up smoothly and carefully to reduce the
possibility of flipping the tractor over backward.

TURNING THE TRACTOR
WARNING: Turning the tractor while
traveling at a fast speed may cause the
tractor to overturn.
NOTE: The tractor is equipped with hydraulic power
steering. If front mounted equipment is installed on
the tractor and the engine is running at a slow speed,
it may take increased steering effort to turn the
tractor.
IMPORTANT: When the steering wheel is turned
completely and held in this position, the hydraulic
system may emit a high pitched sound from the relief
valve being actuated. Avoid prolonged turns with the
tractor’s steering wheel held in the completely turned
position.
•

DRIVING ON ROADWAYS

Always slow down the tractor by reducing throttle
speed and/or downshifting the transmission
before turning the tractor.

•

Engagement of the differential lock will prevent
proper steering and could cause loss of tractor
control when turning. Always release the
differential lock pedal and make the certain it is
disengaged before turning the tractor.

•

Use the individual wheel brakes to assist turning
ONLY when the tractor is working in the field and
operating at slower speeds.

WARNING: Ensure proper weighting of
the tractor, and travel at a safe speed
when driving with a rear mounted implement in the raised position. Bouncing of
the implement while traveling at higher
speeds could momentarily raise the front
end of the tractor and result in loss of
steering and control of the tractor.

WARNING: Sudden application of one
brake while traveling at high speed or
while making fast turns could cause the
tractor to roll over.
DRIVING ON SLOPES
WARNING: When climbing or descending
a hill, do not shift the transmission into
the neutral position or disengage the
clutch.
•

Interlock the brake pedals before operating the
tractor on a slope. Never use the individual wheel
brakes when operating on a slope.

•

Operate the tractor up and down slopes, never
across slopes. Do not drive so that the tractor
may tip over sideways.

•

Prior to going uphill, shift the transmission into a
low enough gear to allow the tractor to climb the
hill without lugging down the engine.

•

Make certain the left and right brake pedals are
interlocked before driving on public roads.

•

Attach an SMV (slow moving vehicle) sign in a
visible location on the back of the tractor or rear
mounted equipment.

•

Reduce the speed of the tractor when turning on
sharp curves.

•

Downshift the transmission and use the engine to
brake when descending steep slopes.

•

Use the turn signal to alert other vehicles of your
intentions when making turns.

•

If driving after dusk or before dawn, turn on all the
tractor lights - including the flashing hazard lights.
Dim the headlights to oncoming traffic if using the
high beams.

•

Pay close attention for low shoulders on the side
of the road. Dropping the tractor’s wheels off the
road onto a low shoulder could upset the tractor.

•

Obey all traffic laws and allow faster moving
vehicles to pass. Do not block the road.

this happens, the fuel system should be bled prior to
restarting the engine (refer to MAINTENANCE).

CHECK WHILE OPERATING
While operating the tractor, regularly check the
gauges and warning lights on the instrument panel to
ensure the tractor is functioning properly.

Observed Problems
The engine should be stopped immediately and the
tractor checked if any of the following are observed
while operating the tractor.

Coolant Temperature Light
Regularly check that the gauge needle is within the
normal operating range. If the needle moves into the
red section (overheat) of the gauge, stop the tractor
immediately and check for the following causes:

•
•
•

WARNING: After the engine has been
running for a short period, the radiator,
muffler, engine block, and any metal surface in close proximity to the engine will
be HOT. Allow these areas to cool and
use extreme caution to avoid burns.
WARNING: Do not remove the radiator cap
until the coolant temperature is below its
boiling point. Then carefully loosen the
cap to its first stop to relieve any pressure
before completely removing the cap .
•
•

•
•

The engine suddenly slows down or speeds up.
Unusual noises are suddenly heard.
The engine exhaust suddenly and for no
apparent reason becomes very dark .
NOTE: The engine exhaust is normally colorless.
If the tractor is overloaded the exhaust may
become darker until the load is reduced. Try to
avoid this situation. Operating the tractor in a
prolonged overloaded condition may cause
damage to tractor components.

TRAVEL SPEEDS
Using combinations of shift positions for the main
shifter, Hi-Lo shifter, and forward/reverse shifter, the
tractor can be placed in any of twelve speeds in
forward and twelve speeds in reverse.

Check the coolant level. If coolant is low check for
possible cause, such as a radiator or hose leak.
Check for debris on the screen in front of the radiator. Check the passages between the radiator
cooling fins for accumulations of dust or dirt.
Check for a loose fan drive belt.
Check for internal radiator blockage.

•
•
•

Engine Oil Pressure Lamp
The oil pressure lamp alerts the operator that the
engine oil pressure is below the prescribed level. If
the lamp should light during operation, stop the
engine immediately.
• Check the engine oil level. If the oil level is within
the operating range, contact your Cub Cadet dealer.
NOTE: If the engine is left running at idle speed for a
prolonged period, the oil pressure lamp may light.
This does not indicate a problem with the engine, but
this situation should be avoided.

Fully depress the clutch pedal before shifting any
of the transmission shift levers.
Do not shift the Hi-Lo range shifter while the
tractor is moving. Stop the tractor before shifting.

USING THE DIFFERENTIAL LOCK

USING THE FRONT WHEEL DRIVE

Depressing the differential lock pedal engages a
mechanism in the transmission that locks the
differential. This prevents the rear wheels from
rotating independently of each other and provides
constant power to both rear wheels when additional
traction is needed.

Use the front wheel drive when the conditions require
the additional traction provided by all four wheels
driving the tractor.
For example:
•

When operating ground engaging equipment,
such as a front end loader, that may cause the
rear wheels to break traction.

•

When climbing slopes.

•

When operating in wet, sandy or loose soil
conditions.

IMPORTANT: Do not engage the differential
lock when one of the rear wheels is rotating. Stop
the wheel rotation and then engage the
differential lock.
WARNING: When operating with the differential lock engaged, the tractor will be
difficult to steer. Do not drive the tractor
on roadways or at high speeds with the
differential lock engaged.
•

To engage the front wheel drive mechanism, depress
the clutch pedal, stop the tractor, and push the front
wheel drive lever downward. See Figure 30.

Using your heel, fully depress and hold the
differential lock pedal to engage the transmission
differential lock. Release the pedal to disengage
the differential lock. See Figure 29.

•

Apply the differential lock moderately. Limit its
use to situations where the tractor is stopped or is
unable to drive straight because one its rear
wheels has lost traction due to slippery or loose
soil.

•

Do not engage the differential lock for prolonged
periods. Release the pedal when traction has
been restored.

USING THE POSITION CONTROL AND DRAFT
CONTROL LEVERS

NOTE: Because of the drive load on the internal
engagement mechanism, releasing the pedal may not
always disengage the differential lock even though
the pedal springs back. It may be necessary to slow
the tractor, or engage the brake pedal, to disengage
the differential lock.

•

Use the position control lever to set the height of
a 3-point hitch mounted implement if drag on the
tractor is not a concern.

•

Set the draft control lever to control the drag on
the tractor when operating a 3-point hitch
mounted implement. Draft control will maintain a
constant pull on the tractor by continually raising
and lowering the implement as different soil
conditions are experienced.

•

Use a combination of the two levers to set the
height of the implement while also controlling the
drag on the tractor. Refer to Figure 31.

TRACTOR WEIGHTING

USING REMOTE HYDRAULICS
The tractor is equipped with a remote hydraulic
system for powering hydraulically driven implements
that are approved for usage on the tractor.

When implements are installed on either the front or
rear of a tractor, the tractor’s normal balance is altered.
• As a rear mounted implement is raised to the
transport position, the balance point of the tractor
shifts rearward, which may result in a loss of
steering control and tractor stability.

WARNING: To avoid personal injury, stop
the tractor engine and relieve pressure
from the hydraulic system before
connecting or disconnecting lines. Do
not use your hand to check for leaks.

•

Connecting Implements
• Clean the hydraulic couplers on both the tractor
and implement.
• Remove the dust plugs and/or caps from the
couplers. See Figure 37.

When a front mounted implement is raised, the
balance point shifts forward and may result in a
loss of traction and stability.

To counterbalance these weight shifts, weight should
be added to the tractor in the form of cast iron
weights or liquid ballast. However, only enough
weight should be added to obtain good traction, control, and stability. Excessive weight will unnecessarily
load down the tractor’s engine and transmission.
NOTE: When adding weight to the tractor, it may be
necessary to increase inflation pressure in the tires.

Front Weights
To counterbalance three point hitch mounted
equipment, weight should be added to the front of the
tractor. Add enough ballast to maintain steering
control and prevent tip over. Remove the weight
when it is not needed. Front weights are available at
your Cub Cadet dealer.
Follow the guidelines provided in the implement
Operator’s Manual to determine how much weight is
needed to counterbalance the equipment. If
guidelines are not available, ballast the tractor so that
a minimum of approximately 40% of the machine
weight is on the front wheels.
If necessary, contact your Cub Cadet dealer for help
in determining how much weight is needed for your
particular application.

•

Insert the implement coupler into the tractor
hydraulic coupler.
• Pull slightly on the implement couplers to make
certain they are firmly connected to the tractor.
Disconnecting Implements
• Lower the implement to the ground to release
hydraulic pressure in the hoses.
• Relieve pressure by moving the hydraulic control
lever in each direction several times with the
engine shut off.
• Pull each implement hose coupler straight from
the hydraulic coupler to release it.
• Clean oil and dust from each coupler and replace
the dust plugs and/or caps.

Weighting the Rear of the Tractor
Add weight to the rear wheels if needed to improve
traction or for stability. The amount of rear ballast
should be matched to the job, and the ballast should
be removed when it is not needed. The most common
methods of adding weight are filling the rear wheels
with liquid ballast or mounting a rear weight box.
Liquid Ballast
Because special equipment and a familiarity with the
practice is required, only a qualified tire technician
should perform this procedure. Consult with your Cub
Cadet dealer about having liquid ballast added to
your tires, and for any special maintenance
instructions after the procedure is performed.

Remote Control Valve Lever
Move the lever up or down and hold. This will raise or
lower the implement. The lever will return to neutral
when released.
IMPORTANT: Do not hold the lever in the "pull" or
"push" position once the remote cylinder has reached
the end of its stroke. Doing so will force oil through
the relief valve, and over a prolonged period cause
the hydraulic oil to overheat.

Rear Weight Box
Consult with your Cub Cadet dealer about available
rear weight boxes. Your dealer can help in
determining the positioning of the box and the amount
of weight needed for your particular application.

IMPORTANT: When using the tractor hydraulic
system to power a front loader, do not operate the
boom and bucket cylinders simultaneously.

Free Play

Figure 43
IMPORTANT: Free travel of the clutch pedal is
governed by the clearance between the clutch’s
release thrust bearing and the release levers. This
clearance is set from 0.098 to 0.12 inches (2.5 to 3
mm) when the tractor is built, but this changes as the
tractor is used. If the pedal is used with no clearance,
it will result in the seizure of the release bearing or
wear of the facing. Therefore, be sure to check and
adjust at the intervals called for in the maintenance
schedule.

To Adjust
•

Open the clutch access window which is located
on the right front of the clutch housing.

•

Insert a 0.098 to 0.12 inch (2.5 to 3.0 mm) feeler
gauge between the release thrust bearing and
the release levers. Adjust the clearance by
adjusting the length of the clutch rod.
- Lengthen the rod if the clearance is wider than
the specification.
- Shorten the rod if the clearance is less than the
specification.

With the clutch pedal fully depressed, confirm
that there is adequate gap between the clutch rod
and the safety start switch.

IMPORTANT: When adjusting the clutch pedal free
travel, always use measuring devices rather than
visually estimating distances.

•

Raise the switch slightly and recheck the position
of the lower links when the PTO shuts off.

•

If necessary, repeat the above step until the PTO
shut-off height of the lower links is adequate for
your application. The switch can be adjusted so
that the lower links can be raised to approximately 35.8 inches before the PTO will be
disengaged.

ADJUSTING WHEEL TREAD
When operating the tractor in the field, it is sometimes
necessary to change the rear wheel tread to a
narrower position to avoid plant rows, or to widen the
tread to improve stability when operating on slopes.
The rear wheel tread width can be adjusted to any of
6 different positions ranging from 46.4 to 58.6 inches
by changing the position of the wheel disc relative to
the rim mounting brackets and the rear axle.

ADJUSTING THE MICRO SWITCH HEIGHT
The PTO micro switch, located on the right fender
aside the position control lever, is initially set so that
the PTO will disengage when the 3-point hitch lower
links are raised to approximately 23.6 to 26 inches.

CHECKING STEERING WHEEL
If it is difficult to drive the tractor in a straight line,
check the play in the steering wheel. Acceptable
steering wheel play is 0.8 to 2.0 inches (24 to 50 mm)
as measured at the outer circumference of the
steering wheel. If your steering wheel free play
exceeds the acceptable range, contact your Cub
Cadet dealer to have the tractor inspected.

IMPORTANT: When changing the tread width of the
rear wheels, you must pay attention to the direction of
the tire’s tread design and make certain to maintain
that direction. To do this, it will at times be necessary
to switch wheel assemblies from one side of the
tractor to the other.

SERVICING THE COOLING SYSTEM
Before each use, the engine coolant level in the
overflow reservoir should be checked to ensure it is
within the operating range. Engine coolant absorbs
heat from the engine and transfers the heat to the air
flowing through the radiator. If the coolant level
becomes low, the engine may overheat and could
cause severe damage to the engine.
Use a permanent type antifreeze containing corrosion
and rust inhibitors. Dilute the antifreeze with water at a
1:1 ratio to mix the coolant solution (50% antifreeze :
50% water).

•

Cap

Locate the radiator cap beneath the access door
at the forward end of the hood. Turn the radiator
cap counterclockwise to the first stop to release
any pressure. Refer to Figure 65.
Push downward on the cap and turn counterclockwise until the cap stops then lift cap off.
Slowly pour coolant mixture into the filler neck
until the level reaches the bottom of the filler neck
overflow flange.
Wait a few minutes to allow as much air as
possible to escape through the filler neck, then
reinstall the radiator cap.
Fill the overflow reservoir to the "FULL" mark.
Start the engine and allow it to run for a short
period. Stop the engine.
Recheck the coolant level in the overflow
reservoir and refill as needed. Reinstall the
reservoir cap.

Checking and Cleaning Radiator Screen
The radiator screen is designed to catch debris, and
prevent it from clogging the air passages between the
radiator cooling fins. See Figure 66.
Check the radiator screen daily and blow off any
minor accumulations of debris using compressed air
directed from the fan shroud side of the radiator.
NOTE: During certain times of year it may be
necessary to clean the screen more often.
If the screen becomes extremely dirty, remove the
wing bolt and slide the screen out from the right side
of the tractor. Flush the screen with water. Reinsert
the screen and secure with the wing nut.

When Engine is Difficult To Start
Cause
Fuel is thick and doesn’t flow

Countermeasures
- Check the fuel tank and fuel filter.
- Remove water, dirt and other impurities.
- Check the fuel filter element for water, dirt , or other impurities, and
replace the filter if necessary.

Air or water mixed in fuel system

- If air is in the fuel filter or injection lines, the fuel pump will not work
properly. To attain proper fuel injection pressure, check carefully for
loosened fuel cap nut, etc.
- Loosen air vent screw over fuel filter and fuel injection pump to eliminate
all the air in the fuel system.

Thick carbon deposits on orifice of
injection nozzle

- This is caused when water or dirt is mixed in the fuel. Clean the nozzle
injection piece, being careful not to damage the orifice.
- Check to see if nozzle is working properly. If not, install a new nozzle.

Valve clearance is wrong

- Adjust valve clearance:
Intake — 0.0098 in. (0.25mm)
Exhaust — 0.0118 in. (0.3mm)

Leaking valves

- Grind valve

Fuel injection timing is wrong

- Adjust injection timing.
- The injection timing is 18° before top dead center.

Engine oil becomes thick in cold
weather and engine cranks slowly.

- Change grade of oil according to the weather (ambient temperature).

Low compression

- Bad valve or excessive wear of rings, pistons and liners cause
insufficient compression. Replace with new parts.

Battery is discharged and the engine
will not crank

- Charge battery.
- In the winter, always remove battery from tractor, fully charge, and keep
indoors. Install in tractor at time of use.

When Output Is Insufficient
Cause
Carbon build-up around orifice of
nozzle piece

Countermeasures
- Clean orifice and needle valve, while being very careful not to damage
the nozzle orifice.
- Check nozzle. If defective, replace with new parts.

Compression is insufficient

- Bad valve and excessive wear of rings, pistons, and liners cause
insufficient compression. Replace with new parts.
- Grind valves.

Overheating of moving parts

- Check engine lubrication system.
- Check to see if lube oil filter is working properly.
- Filter screens or elements deposited with impurities would cause poor
lubrication. Clean Screens.
- Check to see if bearing clearances ar within factory specifications.
- Check engine timing. Adjust timing to 18° before top dead center.

Valve out of adjustment

- Adjust to proper valve clearance:
Intake — 0.0098 in. (0.25mm)
Exhaust — 0.0118 in. (0.3mm)

Air cleaner is dirty

- Clean the element and dust cup weekly, and replace element after
every 100 hours of operation.

Fuel injection pressure is wrong

- Adjust to proper pressure of 2.000 psi (140 kgf/cm2 - 13.7 KPa).

Injection pump wear

- Do not use poor quality fuel because it will cause wear of the the pump.
Only use No. 2 diesel fuel.
- Check the fuel injection pump element and delivery valve assembly and
replace as necessary.

When Color of Exhaust Is Especially Bad
See your Cub Cadet dealer.
Cause

Countermeasures

Fuel governing device is bad

- Contact your dealer for repairs.

Fuel is of extremely poor quality

- Select good quality fuel:
Above 14°F (-10°C) — No. 2 Diesel fuel
Below 14°F (-10°C) — No. 1 Diesel fuel

Nozzle is bad

- If necessary, replace with new nozzle.

Combustion is incomplete

- Cause is poor atomization, improper injection timing, etc. because of
trouble in the injection system, or because of poor valve adjustment,
compression leakage, poor compression, etc. Check for the cause and
repair.

When Engine Suddenly Stops
Cause
Fuel Leakage

Countermeasures
- Check the fuel tank and refill if necessary.
- Check fuel system for air or leaks.
