Service  
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.  
23. If situations occur which are not covered in this manual,  
use care and good judgment. Contact your dealer for  
assistance. Telephone 1-800-800-7310 for the name of  
your nearest dealer.  
2. Wash your skin and change clothes immediately.  
3. Use only an approved gasoline container.  
4. 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. 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.  
6. 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.  
7. Extinguish all cigarettes, cigars, pipes and other sources  
of ignition.  
Slope Operation  
Slopes are a major factor related to slip and fall accidents  
which can result in severe injury. Operation on slopes  
requires extra caution. If you feel uneasy on a slope, 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,  
do not mow it.  
Do:  
1. Mow across the face of slopes; never up and down.  
Exercise extreme caution when changing direction on  
slopes.  
2. Watch for holes, ruts, rocks, hidden objects, or bumps  
which can cause you to slip or trip. Tall grass can hide  
obstacles.  
8. Never fuel machine indoors because flammable vapors  
will accumulate in the area.  
3. Always be sure of your footing. A slip and fall can cause  
serious personal injury. If you feel you are losing your  
balance, release the blade control handle immediately,  
and the blade will stop rotating within 3 seconds.  
9. Never remove gas cap or add fuel while the engine is hot  
or running. Allow engine to cool at least two minutes  
before refueling.  
10. Never over fill fuel tank. Fill tank to no more than ½ inch  
below bottom of filler neck to provide space for fuel  
expansion.  
11. Replace gasoline cap and tighten securely.  
12. If gasoline is spilled, wipe it off the engine and equipment.  
Move unit to another area. Wait 5 minutes before starting  
the engine.  
13. 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.  
Do Not:  
1. Do not mow near drop-offs, ditches or embankments, you  
could lose your footing or balance.  
2. Do not mow slopes greater than 15 degrees as shown on  
the slope gauge.  
3. Do not mow on wet grass. Unstable footing could cause  
slipping.  
Children  
14. To reduce fire hazard, keep mower free of grass, leaves,  
or other debris build-up. Clean up oil or fuel spillage and  
remove any fuel soaked debris.  
Tragic accidents can occur if the operator is not alert to the  
presence of children. Children are often attracted to the  
mower and the mowing activity. They do not understand the  
dangers. Never assume that children will remain where you  
last saw them.  
15. Allow a mower to cool at least 5 minutes before storing.  
General Service:  
1. Keep children out of the mowing area and under the  
watchful care of a responsible adult other than the  
operator.  
1. Never run an engine indoors or in a poorly ventilated  
area. Engine exhaust contains carbon monoxide, an  
odorless and deadly gas.  
2. Be alert and turn mower off if a child enters the area.  
3. Before and while moving backwards, look behind and  
down for small children.  
4. Use extreme care when approaching blind corners,  
doorways, shrubs, trees, or other objects that may  
2. Before cleaning, repairing, or inspecting, make certain  
the blade and all moving parts have stopped. Disconnect  
the spark plug wire and ground against the engine to  
prevent unintended starting.

3. Check the blade and engine mounting bolts at frequent  
intervals for proper tightness. Also, visually inspect blade  
for damage (e.g., bent, cracked, worn) Replace blade  
with the original equipment manufacture’s (O.E.M.) blade  
only, listed in this manual. “Use of parts which do not  
meet the original equipment specifications may lead to  
improper performance and compromise safety!”  
4. Mower blades are sharp and can cut. Wrap the blade or  
wear gloves, and use extra caution when servicing them.  
5. Keep all nuts, bolts, and screws tight to be sure the  
equipment is in safe working condition.  
9. Grass catcher components, discharge cover, and trail  
shield are subject to wear and damage which could  
expose moving parts or allow objects to be thrown. For  
safety protection, frequently check components and  
replace immediately with original equipment  
manufacturer’s (O.E.M.) parts only, listed in this manual.  
“Use of parts which do not meet the original equipment  
specifications may lead to improper performance and  
compromise safety!”  
10. Do not change the engine governor setting or overspeed  
the engine. The governor controls the maximum safe  
operating speed of the engine.  
11. Maintain or replace safety and instruction labels, as  
necessary.  
6. Never tamper with safety devices. Check their proper  
operation regularly.  
7. After striking a foreign object, stop the engine, disconnect  
the spark plug wire and ground against the engine.  
Thoroughly inspect the mower for any damage. Repair  
the damage before starting and operating the mower.  
8. Never attempt to make a wheel or cutting height  
adjustment while the engine is running.  
12. Observe proper disposal laws and regulations. Improper  
disposal of fluids and materials can harm the  
environment.

usually indicate that the air cleaner should be  
serviced. To service the air cleaner, refer to the  
separate engine manual packed with your unit.  
The spark plug should be cleaned and the gap  
reset once a season. Spark plug replacement is  
recommended at the start of each mowing season.  
Clean the engine regularly with a cloth or brush.  
Keep the cooling system (blower housing area)  
clean to permit proper air circulation which is  
essential to engine performance and life. Be certain  
to remove all grass, dirt, and combustible debris  
from muffler area.  
Lubrication  
WARNING: Always stop engine and  
disconnect spark plug wire before  
cleaning, lubricating or doing any kind of  
service work on the lawn mower.  
Deck  
Blade Control: Lubricate the pivot points on the blade  
control handle at least once a season with light oil. The  
blade control must operate freely in both directions.  
See Figure 15.  
The underside of the mower deck should be cleaned  
after each use to prevent a buildup of grass clippings,  
leaves, dirt, or other matter. If this debris is allowed to  
accumulate, it will invite rust and corrosion, and may  
prevent proper mulching, discharge, or bagging. The  
deck may be cleaned by tilting the mower and scraping  
clean with a suitable tool (make certain the spark plug  
wire is disconnected).  
Wheels: Lubricate the wheels at least once a season  
with light oil (or motor oil). If the wheels are removed for  
any reason, lubricate the surface of the axle bolt and  
inner surface of the wheel with light oil. See Figure 15.  
Engine: Follow the separate engine manual packed  
with you unit for lubrication instructions.  
IMPORTANT:We do not recommend the use of a  
pressure washer or garden hose to clean your unit.  
Cutting Blade Removal, Replacement, and Sharpening  
When removing the cutting blade for sharpening or  
replacement, protect your hands with a pair of  
heavy gloves or use a heavy rag to hold the blade.  
Remove the bolt and the blade bell support which  
hold the blade and the blade adapter to the engine  
crankshaft. See Figure 16.  
Lubricate  
Remove the blade and the adapter from the  
crankshaft.  
WARNING: Periodically inspect the blade  
adapter for cracks, especially if you strike  
a foreign object. Replace when necessary.

MANUFACTURERS LIMITED WARRANTY FOR:  
c. Routine maintenance items such as lubricants, filters,  
blade sharpening and tune-ups, or adjustments such as  
brake adjustments, clutch adjustments or deck adjust-  
ments; and normal deterioration of the exterior finish due  
to use or exposure.  
The limited warranty set forth below is given by MTD PROD-  
UCTS INC (MTD) with respect to new merchandise pur-  
chased and used in the United States, its possessions and  
territories.  
d. MTD does not extend any warranty for products sold or  
exported outside of the United States of America, its  
possessions and territories, except those sold through  
MTDs authorized channels of export distribution.  
MTD warrants this product against defects in material and  
workmanship for a period of two (2) years commencing on  
the date of original purchase and will, at its option, repair or  
replace, free of charge, any part found to be defective in  
material or workmanship. This limited warranty shall only  
apply if this product has been operated and maintained in  
accordance with the Operators Manual furnished with the  
product, and has not been subject to misuse, abuse, com-  
mercial use, neglect, accident, improper maintenance, alter-  
ation, vandalism, theft, fire, water or damage because of  
other peril or natural disaster. Damage resulting from the  
installation or use of any accessory or attachment not  
approved by MTD Products Inc. for use with the product(s)  
covered by this manual will void your warranty as to any  
resulting damages.  
No implied warranty, including any implied warranty of  
merchantability or fitness for a particular purpose,  
applies after the applicable period of express written  
warranty above as to the parts as identified. No other  
express warranty or guaranty, whether written or oral,  
except as mentioned above, given by any person or  
entity, including a dealer or retailer, with respect to any  
product shall bind MTD. During the period of the War-  
ranty, the exclusive remedy is repair or replacement of  
the product as set forth above. (Some states do not allow  
limitations on how long an implied warranty lasts, so the  
above limitation may not apply to you.)  
Normal wear parts or components thereof are subject to sep-  
arate terms as follows: All normal wear part or component  
failures will be covered on the product for a period of 90 days  
regardless of cause. After 90 days, but within the two year

include, but are not limited to, belts, blades, blade adapters,  
grass bags, rider deck wheels, seats, snow thrower skid  
shoes, shave plates and tires. Batteries are covered by a 90-  
day limited replacement warranty.  
The provisions as set forth in this Warranty provide the

damages including, without limitation, expenses  
incurred for substitute or replacement lawn care ser-  
vices, for transportation or for related expenses, or for  
rental expenses to temporarily replace a warranted prod-  
uct. (Some states do not allow the exclusion or limitation of  
incidental or consequential damages, so the above exclusion  
or limitation may not apply to you.)
