23. Muffler and engine become hot and can cause a  
burn. Do not touch.  
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.  
24. Check overhead clearances carefully before driving  
under low hanging tree branches, wires, door  
openings etc., where the operator may be struck or  
pulled from the unit, which could result in serious  
injury.  
25. Disengage all attachment clutches, depress the  
brake pedal completely and shift into neutral before  
attempting to start engine.  
26. Your machine is designed to cut normal residential  
grass of a height no more than 10”. Do not attempt  
to mow through unusually tall, dry grass (e.g.,  
pasture) or piles of dry leaves. Dry grass or leaves  
may contact the engine exhaust and/or build up on  
the mower deck presenting a potential fire hazard.  
7. Avoid starting or stopping on a slope. If tires lose  
traction, disengage the blade(s) and proceed  
slowly straight down the slope.  
27. Use only accessories and attachments approved  
for this machine by the machine manufacturer.  
Read, understand and follow all instructions  
provided with the approved accessory or  
attachment.  
DO NOT:  
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.  
28. Data indicates that operators, age 60 years and  
above, are involved in a large percentage of riding  
mower-related injuries. These operators should  
evaluate their ability to operate the riding mower  
safely enough to protect themselves and others  
from serious injury.  
3. Do not try to stabilize the machine by putting your  
foot on the ground.  
29. If situations occur which are not covered in this  
manual, use care and good judgment. Contact your  
customer service representative for assistance.  
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).  
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 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.  
CHILDREN  
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.  
DO:  
1. Mow up and down slopes, not across. Exercise  
extreme caution when changing direction on  
slopes.  
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.  
2. Watch for holes, ruts, bumps, rocks, or other  
hidden objects. Uneven terrain could overturn the  
machine. Tall grass can hide obstacles.

c. Before and while backing, look behind and  
down for small children.  
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. Never carry children, even with the blade(s)  
shut off. They may fall off and be seriously  
injured or interfere with safe machine  
operation.  
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.  
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. Disengage the cutting blade(s) before  
shifting in reverse. The “No-Cut-In Reverse”  
feature is a reminder not to cut in reverse and  
to help avoid back over accidents. Do not  
defeat it.  
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.  
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.  
9. 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.  
TOWING  
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  
1. Tow only with a machine that has a hitch designed  
for towing. Do not attach towed equipment except  
at the hitch point.  
appliances.  
2. Follow the manufacturers recommendation for  
weight limits for towed equipment and towing on  
slopes.  
m. Allow a machine to cool at least five minutes  
before storing.  
GENERAL SERVICE:  
3. Never allow children or others in or on towed  
equipment.  
1. Never run an engine indoors or in a poorly  
ventilated area. Engine exhaust contains carbon  
monoxide, an odorless, and deadly gas.  
2. 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.  
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.  
SERVICE  
3. 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.  
4. Check brake operation frequently as it is subjected  
to wear during normal operation. Adjust and service  
as required.  
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.  
5. 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).

Mowing  
WARNING: To help avoid blade contact or  
a thrown object injury, keep bystanders,  
helpers, children and pets at least 75 feet  
from the machine while it is in operation. Stop  
machine if anyone enters the area.  
WARNING: Before leaving the operator’s  
position for any reason, disengage the  
blades, place the shift lever in neutral,  
engage the parking brake, shut engine off  
and remove the key.  
The following information will be helpful when using the  
cutting deck with your tractor.  
IMPORTANT: When stopping the tractor for any reason  
while on a grass surface, always  
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.  
•
•
•
Place the shift lever in neutral,  
Engage the parking brake,  
Shut engine off and remove the key.  
Doing so will minimize the possibility of having your  
lawn ‘‘browned’’ by hot exhaust from your tractor’s  
running engine.  
•
•
Be sure that the lawn is clear of stones, sticks, wire,  
or other objects which could damage lawn mower  
or engine.  
For best results and to insure more even grass  
distribution, do not mow when lawn is excessively  
wet.  
Do not mow at high ground speed, especially if a  
mulch kit or grass collector is installed.  
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.  
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 19 of this  
manual for proper blade sharpening instructions.  
If unit stalls with speed control in high speed, or if unit  
will not operate with speed control lever in a low speed  
position, proceed as follows.  
•
•
•
•
•
•
•
Place shift lever in NEUTRAL.  
Restart engine.  
Place speed control lever in high speed position.  
Release clutch-brake pedal fully.  
Depress clutch-brake pedal.

To engage power to the cutting deck or other  
(separately available) attachment, proceed as follows:  
•
•
•
•
•
Move the deck engagement/lift lever to the right  
and forward,  
Place the lever a notch for your desired cutting  
height.  
Moving the lever to the right and all the way  
rearward placing it into the BLADES STOP position  
raises and disengages power to the cutting deck.

•
Connect end of one jumper cable to the positive  
terminal of the good battery, then the other end to  
the positive terminal of the dead battery.  
The blade can be tested by balancing it on a round  
shaft screwdriver. Grind metal from the heavy side until  
it balances evenly.  
•
Connect the other jumper cable to the negative  
terminal of the good battery, then to the frame of  
the unit with the dead battery.  
When replacing the blade, be sure to install the blade  
with the side of the blade marked ‘‘Bottom’’ (or with a  
part number stamped in it) facing the ground when the  
mower is in the operating position.  
WARNING: Failure to use this procedure  
could cause sparking, and the gas in either  
battery could explode.  
Cleaning  
IMPORTANT: Use a torque wrench to tighten the blade  
spindle hex flange nut to between 70 foot-pounds and  
90 foot-pounds.  
Clean the battery by removing it from the tractor and  
washing with a baking soda and water solution. If  
necessary, scrape the battery terminals with a wire  
brush to remove deposits. Coat terminals and exposed  
wiring with grease or petroleum jelly to prevent  
corrosion.  
Battery  
The battery is sealed and is maintenance-free. Acid  
levels cannot be checked.  
Battery Failures  
Some common causes for battery failure are:  
•
Always keep the battery cables and terminals clean  
and free of corrosive build-up.  
• incorrect initial activation  
• overcharging  
• freezing  
These failures are NOT covered by your tractor’s  
warranty.  
• undercharging  
• corroded connections  
•
After cleaning the battery and terminals, apply a  
light coat of petroleum jelly or grease to both  
terminals  
•
Always keep the rubber boot positioned over the  
positive terminal to prevent shorting.  
IMPORTANT: If removing the battery for any reason,  
disconnect the NEGATIVE (Black) wire from it’s  
terminal first, followed by the POSITIVE (Red) wire.  
When re-installing the battery, always connect the  
POSITIVE (Red) wire its terminal first, followed by the  
NEGATIVE (Black) wire. Be certain that the wires are  
connected to the correct terminals; reversing them  
could change the polarity and cause damage to your  
engine’s alternating system.  
Tires  
Recommended operating tire pressure is  
approximately 10 p.s.i. Maximum tire pressure under  
any circumstances is 30 p.s.i. Equal tire pressure  
should be maintained on all tires.  
When installing a tire to the rim, be certain rim is clean  
and free of rust. Lubricate both the tire and rim  
generously. Never inflate to over 30 p.s.i. to seat  
beads.  
Charging  
WARNING: Excessive pressure (over 30  
p.s.i.) when seating beads may cause tire/rim  
assembly to burst with force sufficient to  
cause serious injury.  
If the tractor has not been put into use for an extended  
period of time, charge the battery with an automotive-  
type 12-volt charger for a minimum of one hour at six  
amps.  
WARNING: Batteries give off an explosive  
gas while charging. Charge battery in a well  
ventilated area and keep away from an open  
flame or pilot light as on a water heater, space  
heater, furnace, clothes dryer or other gas  
appliances.  
Belt Replacement  
WARNING: Shut the engine off, remove  
ignition key, set the parking brake, disconnect  
the spark plug wire(s) and ground against the  
engine to prevent unintended starting before  
replacing belts.  
Jump Starting  
For performing service on your tractor and in order to  
properly mount some (separately available)

SECTION 9: OFF-SEASON STORAGE  
•
•
Lubricate all lubrication points. Wipe the entire  
machine with an oiled rag to protect the surfaces.  
WARNING: Never store the machine or  
fuel container indoors where there is an  
open flame, spark or pilot light such as on  
water heater, furnace, clothes dryer or other  
gas appliance.  
Refer to the engine manual for correct engine  
storage instructions. The engine must be  
completely drained of fuel to prevent gum deposits  
from forming on essential carburetor parts, fuel  
lines and fuel tanks.  
WARNING: Use a fuel stabilizer additive  
or drain the fuel into an approved container  
outdoors, away from an open flame. Allow  
engine to cool. Extinguish cigarettes, cigars,  
pipes, and other sources of ignition prior to  
draining fuel. Fuel left in engine without a  
stabilizer additive for extended periods  
deteriorates and will cause problems.  
Charge battery fully. The battery loses some of its  
charge each day when the unit is not used.  
NEVER store battery without a full charge. Recharge  
battery before returning to service or every two months,  
whichever occurs first.  
•
When storing unit for extended periods, disconnect  
battery cables. Removing battery from unit is  
recommended.  
If the machine is to be inoperative for a period longer  
than 30 days, prepare for storage as follows.  
•
Store unit in a clean, dry area. Do not store next to  
corrosive materials, such as fertilizer.  
•
•
Clean the engine and the entire unit thoroughly.  
We do not recommend the use of pressure  
washers or garden hose to clean your unit. They  
may cause damage to electric components,  
spindles, pulleys, bearings or the engine. The use  
of water will result in shortened life and reduce  
serviceability.  
NOTE: When storing any type of power equipment in  
an unventilated or metal storage shed, care should be  
taken to rustproof the equipment. Using a light oil or  
silicone, coat the equipment, especially any chains,  
springs, bearings and cables.
