HEED ITS WARNING

WARNING: Engine Exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to State of California to cause cancer and
birth defects or other reproductive harm.
DANGER: This machine was built to be operated according to the rules for safe operation in this
manual. As with any type of power equipment, carelessness or error on the part of the operator can
result in serious injury. This machine is capable of amputating hands and feet and throwing objects.
Failure to observe the following safety instructions could result in serious injury or death.

Children

Operation

1. Tragic accidents can occur if the operator is not
alert to the presence of children. Children are often
attracted to the machine and the mowing activity.
They do not understand the dangers. Never assume
that children will remain where you last saw them.
a. Keep children out of the mowing area and in
watchful care of a responsible adult other than
the operator.
b. Be alert and turn machine off if a child enters
the area.
c. Before and while backing, look behind and
down for small children.
d. Never carry children, even with the blade(s)
shut off. They may fall off and be seriously
injured or interfere with safe machine operation.
e. Use extreme care when approaching blind
corners, doorways, shrubs, trees or other
objects that may block your vision of a child
who may run into the machine.
f. To avoid back-over accidents, always
disengage the cutting blade(s) before
shifting into Reverse. If equipped, the
“Reverse Caution Mode” should not be
used when children or others are around.
g. Keep children away from hot or running
engines. They can suffer burns from a hot
muffler.
h. Remove key when machine is unattended to
prevent unauthorized operation.
2. Never allow children under 14 years old to operate
the machine. Children 14 years old and over should
read and understand the operation instructions and
safety rules in this manual and should be trained and
supervised by a parent.

Safe Handling of Gasoline:
1. To avoid personal injury or property damage use

extreme care in handling gasoline. Gasoline is
extremely flammable and the vapors are explosive. Serious personal injury can occur when gasoline
is spilled on yourself or your clothes which can ignite.
Wash your skin and change clothes immediately.
a. Use only an approved gasoline container.
b. Never fill containers inside a vehicle or on a
truck or trailer bed with a plastic liner. Always
place containers on the ground away from
your vehicle before filling.
c. When practical, remove gas-powered
equipment from the truck or trailer and refuel it
on the ground. If this is not possible, then
refuel such equipment on a trailer with a
portable container, rather than from a gasoline
dispenser nozzle.
d. Keep the nozzle in contact with the rim of
the fuel tank or container opening at all
times until fueling is complete. Do not use a
nozzle lock-open device.
e. Extinguish all cigarettes, cigars, pipes and
other sources of ignition.
f. Never fuel machine indoors.
g. Never remove gas cap or add fuel while the
engine is hot or running. Allow engine to cool
at least two minutes before refueling.
h. Never over fill fuel tank. Fill tank to no more
than ½ inch below bottom of filler neck to
allow space for fuel expansion.
i. Replace gasoline cap and tighten securely.
j. If gasoline is spilled, wipe it off the engine
and equipment. Move unit to another area.
Wait 5 minutes before starting the engine.
k. To reduce fire hazards, keep machine free of
grass, leaves, or other debris build-up. Clean
up oil or fuel spillage and remove any fuel
soaked debris.
l. Never store the machine or fuel container
inside where there is an open flame, spark
or pilot light as on a water heater, space
heater, furnace, clothes dryer or other gas
appliances.
m. Allow a machine to cool at least five minutes
before storing.

endanger the personal
safety and/or property
of yourself and others.
Read and follow all
instructions in this manual before attempting to
operate this machine.
Failure to comply with
these instructions may

When you see this
symbol.

Slope Operation:

Do Not:

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 mow
it.
For your safety, use the slope gauge included as part of
this manual to measure slopes before operating this unit
on a sloped or hilly area. If the slope is greater than 15
degrees as shown on the slope gauge, do not operate
this unit on that area or serious injury could result.

1. Do not turn on slopes unless necessary; then, turn
slowly and gradually downhill, if possible.
2. Do not mow near drop-offs, ditches or embankments.
The mower could suddenly turn over if a wheel is over
the edge of a cliff, ditch, or if an edge caves in.
3. Do not try to stabilize the machine by putting your foot
on the ground.
4. Do not use a grass catcher on steep slopes.
5. Do not mow on wet grass. Reduced traction could
cause sliding.
6. Do not shift to neutral and coast downhill. Over-speeding may cause the operator to lose control of the
machine resulting in serious injury or death.
7. Do not tow heavy pull behind attachments (e.g. loaded
dump cart, lawn roller, etc.) on slopes greater than
5 degrees. When going down hill, the extra weight
tends to push the tractor and may cause you to loose
control. (e.g. tractor may speed up, braking and steering ability are reduced, attachment may jack-knife and
cause tractor to overturn).

Do:
1. Mow up and down slopes, not across. Exercise
extreme caution when changing direction on slopes.
2. Watch for holes, ruts, bumps, rocks, or other hidden
objects. Uneven terrain could overturn the machine.
Tall grass can hide obstacles.
3. Use slow speed. Choose a low enough speed
setting so that you will not have to stop or shift while
on the slope. Tires may lose traction on slopes even
though the brakes are functioning properly. Always
keep machine in gear when going down slopes to
take advantage of engine braking action.
4. Follow the manufacturer’s recommendations for
wheel weights or counterweights to improve stability.
5. Use extra care with grass catchers or other attachments. These can change the stability of the
machine.
6. 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.
7. Avoid starting or stopping on a slope. If tires lose
traction, disengage the blade(s) and proceed slowly
straight down the slope.

Towing:
1. Tow only with a machine that has a hitch designed for
towing. Do not attach towed equipment except at the
hitch point.
2. Follow the manufacturers recommendation for weight
limits for towed equipment and towing on slopes.
3. Never allow children or others in or on towed equipment.
4. On slopes, the weight of the towed equipment may
cause loss of traction and loss of control.
5. Travel slowly and allow extra distance to stop.
6. Do not shift to neutral and coast downhill.

READ OPERATOR’S MANUAL

The following information will be helpful when using the
cutting deck with your tractor:

WARNING: Plan your mowing
pattern to avoid discharge of
materials toward roads, sidewalks, bystanders and the like.
Also, avoid discharging material
against a wall or obstruction
which may cause discharged
material to ricochet back toward
the operator.
• Do not mow at high ground speed, especially if a
mulch kit or grass collector is installed.

• Mowing should always be done with the engine at full
throttle.
• Under heavier conditions it may be necessary to go
back over the cut area a second time to get a clean
cut.
• Do NOT attempt to mow heavy brush and weeds and
extremely tall grass. Your tractor is designed to mow
lawns, NOT clear brush.
• Keep the blades sharp and replace the blades when
worn. Refer to Cutting Blades on page 21 of this
manual for proper blade sharpening instructions.

• For best results it is recommended that the first two
laps be cut with the discharge thrown towards the
center. After the first two laps, reverse the direction
to throw the discharge to the outside for the balance
of cutting. This will give a better appearance to the
lawn.
• Do not cut the grass too short. Short grass invites
weed growth and yellows quickly in dry weather.

Mulching (If Equipped)
A mulch kit is sold separately and incorporates special
blades that incorporate a process of recirculating grass
clippings repeatedly beneath the cutting deck. The ultrafine clippings are then forced back into the lawn where
they act as a natural fertilizer.

Operating
Your Lawn
Tractor

Observe the following points for the best results when
mulching:
• Never attempt to mulch if the lawn is damp. Wet grass
tends to stick to the underside of the cutting deck
preventing proper mulching of the clippings.
• Do NOT attempt to mulch more than 1/3 the total
height of the grass or approximately 1-1/2 inches.
Doing so will cause the clippings to clump up beneath
the deck and not be mulched effectively.
• Maintain a slow ground speed to allow the grass
clippings more time to effectively be mulched.
• Always position the throttle control lever in the FAST
(rabbit) position and allow it to remain there while
mowing. Failing to keep the engine at full throttle
places strain on the tractor’s engine and does not
allow the blades to properly mulch grass.
NOTE: It is not necessary to remove the discharge chute
to operate the mower with the mulch kit installed.

Figure 9

Headlights
• On some models, the lamps are ON whenever the
tractor’s engine is running. On other models, the
lamps are ON whenever the ignition key is moved out
of the STOP position.
• On all models, the lamps turn OFF when the ignition
key is moved to the STOP position.

To operate the cutting deck without mulching, simply
remove the mulch plug by unthreading the plastic wing
nut which fastens it to the cutting deck. This will allow the
clippings to discharge out the side. See Figure 9.

NOTE: It is not necessary to remove the
discharge chute to
operate the mower with
the mulch kit installed.

3/8-inch lower than the rear of the deck. Adjust if necessary as follows:
1. With the tractor parked on a firm, level surface, place
the deck lift lever in the top notch (highest position)
and rotate the blade nearest the discharge chute so
that it is parallel with the tractor.

Adjusting
Your Lawn
Tractor

2. Measure the distance from the front of the blade tip to
the ground and the rear of the blade tip to the ground.
The first measurement taken should be between
1/4” and 3/8” less than the second measurement.
Determine the approximate distance necessary for
proper adjustment and proceed, if necessary, to the
next step.
3. Locate the jam nut and lock nut on the front side of the
stabilizer bracket. See Figure 10. After loosening the
jam nut:

WARNING

Figure 10

4. Retighten the jam nut loosened earlier when proper
adjustment is achieved.

Never attempt to
make any adjustments while the
engine is running,
except where specified in the operator’s
manual.

Side to Side
If the cutting deck appears to be mowing unevenly, a side
to side adjustment can be performed. Adjust if necessary
as follows:
1. With the tractor parked on a firm, level surface, place
the deck lift lever in the top notch (highest position)
and rotate both blades so that they are perpendicular
with the tractor.
2. Measure the distance from the outside of the left blade
tip to the ground and the distance from the outside of
the right blade tip to the ground. Both measurements
taken should be equal. If they’re not, proceed to the
next step.
Figure 11

3. Loosen, but do NOT remove, the hex cap screw on
the left deck hanger bracket. See Figure 11.
4. Balance the deck by using a wrench to turn the
adjustment gear (found immediately behind the hex
cap screw just loosened) clockwise/up or counterclockwise/down. The deck is properly balanced when
both blade tip measurements taken earlier are equal.

WARNING: Never attempt to
make any adjustments while
the engine is running, except
where specified in the operator’s

Changing the Deck Belt

WARNING
Be sure to shut the
engine off, remove ignition key, disconnect
the spark plug wire(s)
and ground against
the engine to prevent
unintended starting
before removing the
belt(s).
Avoid the possibility of
a pinching injury. Do
not place your fingers
on the idler spring or
between the belt and a
pulley while removing
the belt.

WARNING: Be sure to shut
the engine off, remove ignition
key, disconnect the spark plug
wire(s) and ground against the
engine to prevent unintended
starting before removing the
belt(s).
The belt on your tractor is subject to wear and should be
replaced if any signs of wear are present.
IMPORTANT: The V-belt found on your tractor are
specially designed to engage and disengage safely. A
substitute (non-OEM) V-belt can be dangerous by not
disengaging completely. For a proper working machine,
use a factory approved belt.
To change or replace the deck belt proceed as follows:
1. Lower the deck by moving the deck lift lever into the
bottom notch on the right fender.
2. Remove the belt guards by removing the self-tapping
screws that fasten them to the deck.
3. Remove the belt keeper rod from around the engine
pulley.
4. Insert a 3/8”-drive ratchet wrench (set to loosen) into
the square hole found in the idler bracket on the left
side of the deck’s surface. See Figure 20.
5. Grasp the ratchet’s handle and pivot it toward the front
of the tractor to relieve tension on the belt.
6. With belt tension relieved, carefully remove the belt
from around the left-hand spindle pulley.

CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board and MTD Consumer Group Inc are pleased to explain the evaporative emission control system warranty on your 2006 lawn
mower. In California, new lawn mower must be designed, built and equipped to meet the State’s stringent anti-smog standards. MTD Consumer Group Inc must
warrant the EECS on your lawn mower for the period of time listed below provided there has been no abuse, neglect or improper maintenance of your lawn mower.
Your EECS may include parts such as the carburetor, fuel-injection system, the ignition system, catalytic converter, fuel tanks, fuel lines, fuel caps, valves,
canisters, filters, vapor hoses, clamps, connectors, and other associated emission-related components.
Where a warrantable condition exists, MTD Consumer Group Inc will repair your lawn mower at no cost to you including diagnosis, parts and labor.
MANUFACTURER’S WARRANTY COVERAGE:
This evaporative emission control system is warranted for two years. If any evaporative emission-related part on your equipment is defective, the part will be
repaired or replaced by MTD Consumer Group Inc.
OWNER’S WARRANTY RESPONSIBILITIES:
As the lawn mower owner, you are responsible for performance of the required maintenance listed in your owner’s manual. MTD Consumer Group Inc recommends that you retain all receipts covering maintenance on your lawn mower, but MTD Consumer Group Inc cannot deny warranty solely for the lack of receipts.
As the lawn mower owner, you should however be aware that MTD Consumer Group Inc may deny you warranty coverage if your lawn mower or a part has failed
due to abuse, neglect, or improper maintenance or unapproved modifications.
You are responsible for presenting your lawn mower to MTD Consumer Group Inc’s distribution center or service center as soon as the problem exists. The
warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days. If you have a question regarding your warranty coverage, you should
contact the MTD Consumer Group Inc Service Department at 1-800-800-7310.
GENERAL EMISSIONS WARRANTY COVERAGE:
MTD Consumer Group Inc warrants to the ultimate purchaser and each subsequent purchaser that the lawn mower is: Designed, built and equipped so as to
conform with all applicable regulations; and free from defects in materials and workmanship that cause the failure of a warranted part to be identical in all material
respects to that part as described in MTD Consumer Group Inc’s application for certification.
The warranty period begins on the date the lawn mower is delivered to an ultimate purchaser or first placed into service. The warranty period is two years.
Subject to certain conditions and exclusions as stated below, the warranty on emission-related parts is as follows:
1. Any warranted part that is not scheduled for replacement as required maintenance in the written instructions supplied, is warranted for the warranty period
stated above. If the part fails during the period of warranty coverage, the part will be repaired or replaced by MTD Consumer Group Inc according to subsection
(4) below. Any such part repaired or replaced under warranty will be warranted for the remainder of the period.
2. Any warranted part that is scheduled only for regular inspection in the written instructions supplied is warranted for the warranty period stated above. Any such
part repaired or replaced under warranty will be warranted for the remaining warranty period.
3. Any warranted part that is scheduled for replacement as required maintenance in the written instructions supplied is warranted for the period of time before the
first scheduled replacement date for that part. If the part fails before the first scheduled replacement, the part will be repaired or replaced by MTD Consumer
Group Inc according to subsection (4) below. Any such part repaired or replaced under warranty will be warranted for the remainder of the period prior to the
first scheduled replacement point for the part.
4. Repair or replacement of any warranted part under the warranty provisions herein must be performed at a warranty station at no charge to the owner.
5. Notwithstanding the provisions herein, warranty services or repairs will be provided at all of our distribution centers that are franchised to service the subject
engines or equipment.
6. The lawn mower owner will not be charged for diagnostic labor that is directly associated with diagnosis of a defective, emission-related warranted part,
provided that such diagnostic work is performed at a warranty station.
7. MTD Consumer Group Inc is liable for damages to other engine or equipment components proximately caused by a failure under warranty of any warranted
part.
8. Throughout the lawn mower warranty period stated above, MTD Consumer Group Inc will maintain a supply of warranted parts sufficient to meet the expected
demand for such parts.
9. Any replacement part may be used in the performance of any warranty maintenance or repairs and must be provided without charge to the owner. Such use will
not reduce the warranty obligations of MTD Consumer Group Inc.
10. Add-on or modified parts that are not exempted by the Air Resources Board may not be used. The use of any non-exempted add-on or modified parts by the
ultimate purchaser will be grounds for disallowing a warranty claims. MTD Consumer Group Inc will not be liable to warrant failures of warranted parts caused
by the use of a non-exempted add-on or modified part.
WARRANTED PARTS:
The repair or replacement of any warranted part otherwise eligible for warranty coverage may be excluded from such warranty coverage if MTD Consumer Group
Inc demonstrates that the lawn mower has been abused, neglected, or improperly maintained, and that such abuse, neglect, or improper maintenance was the
direct cause of the need for repair or replacement of the part. That notwithstanding, any adjustment of a component that has a factory installed, and properly
operating, adjustment limiting device is still eligible for warranty coverage. The following emission warranty parts list are covered: Fuel Line, Fuel Line Clamps

because of other peril or natural disaster. Damage resulting from the
installation or use of any part, accessory or attachment not approved by
Troy-Bilt for use with the product(s) covered by this manual will void your
warranty as to any resulting damage.
