SLOPE OPERATION

DO NOT:
1.
2.

3.
4.
5.
6.

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.

DO:
1.

Mow up and down slopes, not across. Exercise
extreme caution when changing direction on
slopes.
Watch for holes, ruts, bumps, rocks, or other
hidden objects. Uneven terrain could overturn the
machine. Tall grass can hide obstacles.
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.

Follow the manufacturer's recommendations for
wheel weights or counterweights to improve
stability.
Use extra care with grass catchers or other
attachments. These can change the stability of the
machine.
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 blade(s) and proceed
slowly straight down the slope.

Do not turn on slopes unless necessary; then, turn
slowly and gradually downhill, if possible.
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.
Do not try to stabilize the machine by putting your
foot on the ground.
Do not use a grass catcher on steep slopes.
Do not mow on wet grass. Reduced traction could
cause sliding.
Do not shift to neutral and coast downhill. Overspeeding may cause the operator to lose control of
the machine resulting in serious injury or death.
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).

CHILDREN
,

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. Useextremecarewhenapproaching
blind
corners,doorways,
shrubs,treesor other
objectsthatmayblockyourvisionofa child

f. Toavoidback-overaccidents,always
disengagethecuttingblade(s)before
shiftinginto reverse.The"Reverse
CautionMode" should not be used when
children or others are around.
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.
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.
g.

TOWING
1.

3.
4.
5.
6.

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

Extinguish all cigarettes, cigars, pipes and
other sources of ignition.
f. Neverfuel 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 tankto no more
than _/2inch 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.
I. 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 5 minutes
before storing.
GENERAL SERVICE:
1.

SERVICE
SAFE HANDLING OF GASOLINE:
,

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.
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.
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.

6.
7.

Never run an engine indoors or in a poorly
ventilated area. Engine exhaust contains carbon
monoxide, an odorless, and deadly gas.
Before cleaning, repairing, or inspecting, make
certain the blade(s) and all moving parts have
stopped. Disconnect the spark plug wire and
ground against the engine to prevent unintended
starting.
Periodically check to make sure the blades come to
complete stop within approximately (5) five
seconds after operating the blade disengagement
control. If the blades do not stop within the this time
frame, your unit should be serviced professionally
by an authorized MTD Service Dealer.
Check brake operation frequently as it is subjected
to wear during normal operation. Adjust and service
as required.
Check the blade(s) and engine mounting bolts at
frequent intervals for proper tightness. Also,
visually inspect blade(s) for damage (e.g.,
excessive wear, bent, cracked).
Replace the blade(s) with the original equipment
manufacturer's (O.E.M.) blade(s) only, listed in this
manual. "Use of parts which do not meet the
original equipment specifications may lead to
improper performance and compromise safety!"
Mower blades are sharp. Wrap the blade or wear
gloves, and use extra caution when servicing them.
Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.

Fuses
Two fuses are installed in your tractor's wiring harness
to protect the tractor's electrical system from damage
caused by excessive amperage.

To ease in removing the belt in later steps, loosen,
but do not remove, the bolt which secures the
pivoting idler pulley to the idler bracket.
See Figure 19.

Belt Guard

If the electrical system does not function, or your
tractor's engine will not crank, first check to be certain
that the fuse has not blown.
One can be found under the hood mounted behind the
top of the dash panel on the support bar.
The other can be found under the seat mounted to the
inside of the tractor frame next to the battery tray.

•

All belts on your tractor are subject to wear and should
be replaced if any signs of wear are present.

•

IMPORTANT:The V-belts 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 factory approved belts.

WARNING:

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.

To change or replace the deck belt and PTO belt on
your tractor, proceed as follows:
•
•

IMPORTANT:Carefully allow the ratchet to pivot
rearward before removing it from the square hole.

Lower the deck by moving the deck lift lever into the
bottom notch on the right fender.
Remove the belt guards by removing the selftapping screws that fasten them to the deck.
