SECTION 1: IMPORTANT SAFE OPERATION PRACTICES

WARNING: This symbol points out important safety instructions which, if not followed, could 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 result in personal

injury. When you see this symbol—heed its warning.

DANGER: This machine was built to be operated according to the rules for safe operation in this man-

ual. 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.

WARNING: Engine exhaust, some of its constituents, and certain vehicle components contain

or emit chemicals known to the State of California to cause cancer and birth defects or other

reproductive harm.

GENERAL OPERATION

1. Read, understand, and follow all instructions on the

machine and in the manual(s) before attempting to

assemble and operate. Keep this manual in a safe

place for future and regular reference and for

ordering replacement parts.

2. Be familiar with all controls and their proper

operation. Know how to stop the machine and

disengage them quickly.

3. Never allow children under 14 years old to operate

this 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.

4. Never allow adults to operate this machine without

proper instruction.

5. 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.

6. Thoroughly inspect the area where the equipment

is to be used. Remove all stones, sticks, wire,

bones, toys, and other foreign objects which could

be picked up and thrown by the blade(s). Thrown

objects can cause serious personal injury.

7. Plan your mowing pattern to avoid discharge of

material 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.

8. Always wear safety glasses or safety goggles

during operation and while performing an

adjustment or repair to protect your eyes. Thrown

objects which ricochet can cause serious injury to

the eyes.

9. Wear sturdy, rough-soled work shoes and close-

fitting slacks and shirts. Loose fitting clothes and

jewelry can be caught in movable parts. Never

operate this machine in bare feet or sandals.

10. Be aware of the mower and attachment discharge

direction and do not point it at anyone. Do not

operate the mower without the discharge cover or

entire grass catcher in its proper place.

11. Do not put hands or feet near rotating parts or

under the cutting deck. Contact with the blade(s)

can amputate hands and feet.

12. A missing or damaged discharge cover can cause

blade contact or thrown object injuries.

13. Stop the blade(s) when crossing gravel drives,

walks, or roads and while not cutting grass.

14. Watch for traffic when operating near or crossing

roadways. This machine is not intended for use on

any public roadway.

15. Do not operate the machine while under the

influence of alcohol or drugs.

16. Mow only in daylight or good artificial light.

17. Never carry passengers.

18. Disengage blade(s) before shifting into reverse.

Back up slowly. Always look down and behind

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.

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.

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.

29. If situations occur which are not covered in this

manual, use care and good judgment. Contact your

customer service representative for assistance.

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.

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.

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.

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).

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.

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.

5

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. 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.

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

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.

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.

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.

GENERAL SERVICE:

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.

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.

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).

6

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!”

6. Mower blades are sharp. Wrap the blade or wear

gloves, and use extra caution when servicing them.

7. Keep all nuts, bolts, and screws tight to be sure the

equipment is in safe working condition.

8. Never tamper with the safety interlock system or

other safety devices. Check their proper operation

regularly.

9. After striking a foreign object, stop the engine,

disconnect the spark plug wire(s) and ground

against the engine. Thoroughly inspect the

machine for any damage. Repair the damage

before starting and operating.

10. Never attempt to make adjustments or repairs to

the machine while the engine is running.

11. Grass catcher components and the discharge

cover 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!”

12. Do not change the engine governor settings or

over-speed the engine. The governor controls the

maximum safe operating speed of the engine.

13. Maintain or replace safety and instruction labels, as

necessary.

14. Observe proper disposal laws and regulations for

gas, oil, etc. to protect the environment.

for anything other than mowing operations,

the blade drive should be disengaged.

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.

NOTE: The deck engagement/lift lever must be in the

disengaged (BLADES STOP) position when starting

the engine, when traveling in reverse and if the operator

leaves the seat. Refer to Safety Interlock Switches on page

11

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.

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.

• 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.

Deck Leveling Adjustment

WARNING: Protect your hands by wearing

heavy gloves to grasp the cutting blade.

NOTE: Check the tractor’s tire pressure before

performing any deck leveling adjustments. Refer to

Tires later in this section for further information

regarding tire pressure.

The front of the cutting deck is supported by two lift

links, one of which can be adjusted to level the deck

from both front to rear & side to side. The front of the

deck should be between 1/4-inch and 3/8-inch lower

than the rear of the deck. Adjust if necessary as follows:

• With the tractor parked on a firm, level surface,

place the deck engagement/lift lever in the top

cutting height notch (not BLADES STOP) position.

• Rotate the blade nearest the discharge chute so

that it is parallel with the tractor.

• 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.

• Place the deck engagement/lift lever in the

engaged (all the way forward) position.

• Remove the hairpin clip from the ferrule found at

the bottom of the front, left deck link (hairpin clip is

on the inside of the lift link). See Figure 6.

SECTION 9: OFF-SEASON STORAGE

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.

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.

If the machine is to be inoperative for a period longer

than 30 days, prepare for storage as follows.

• 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.

• Lubricate all lubrication points. Wipe the entire

machine with an oiled rag to protect the surfaces.

• 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.

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.

• Store unit in a clean, dry area. Do not store next to

corrosive materials, such as fertilizer.

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.

NOTES

MANUFACTURER’S LIMITED WARRANTY FOR:

The limited warranty set forth below is given by MTD LLC with

respect to new merchandise purchased and used in the

United States, its possessions and territories.

“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

materials or workmanship. This limited warranty shall only

apply if this product has been operated and maintained in

accordance with the Operator’s Manual furnished with the

product, and has not been subject to misuse, abuse,

commercial use, neglect, accident, improper maintenance,

alteration, vandalism, theft, fire, water, or damage because of

other peril or natural disaster. Damage resulting from the

installation or use of any part, accessory or attachment not

approved by MTD for use with the product(s) covered by this

manual will void your warranty as to any resulting damage.

Normal wear parts are warranted to be free from defects in

material and workmanship for a period of thirty (30) days from

the date of purchase. Normal wear parts include, but are not

limited to items such as: batteries, belts, blades, blade

adapters, grass bags, rider deck wheels, seats, snow thrower

skid shoes, shave plates, auger spiral rubber and tires.

HOW TO OBTAIN SERVICE: Warranty service is available,

WITH PROOF OF PURCHASE, through your local authorized

service dealer. To locate the dealer in your area, check your

Yellow Pages, or contact MTD LLC at P.O. Box 361131,

Cleveland, Ohio 44136-0019, or call 1-800-800-7310 or 1-

330-220-4683 or log on to our Web site at

www.mtdproducts.com.

This limited warranty does not provide coverage in the

following cases:

a. The engine or component parts thereof. These items

may carry a separate manufacturer’s warranty. Refer

to applicable manufacturer’s warranty for terms and

conditions.

b. Log splitter pumps, valves, and cylinders have a

separate one year warranty.

c. Routine maintenance items such as lubricants, filters,

blade sharpening, tune-ups, brake adjustments, clutch

adjustments, deck adjustments, and normal

deterioration of the exterior finish due to use or

exposure.

d. Service completed by someone other than an

authorized service dealer.

e. MTD does not extend any warranty for products sold or

exported outside of the United States, its possessions

and territories, except those sold through MTD’s

authorized channels of export distribution.

f. Replacement parts that are not genuine MTD parts.

g. Transportation charges and service calls.

No implied warranty, including any implied warranty of

merchantability of 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, 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 warranty, the

exclusive remedy is repair or replacement of the product

as set forth above.

The provisions as set forth in this warranty provide the

sole and exclusive remedy arising from the sale. MTD

shall not be liable for incidental or consequential loss or

damage including, without limitation, expenses incurred

for substitute or replacement lawn care services or for

rental expenses to temporarily replace a warranted

product.

Some states do not allow the exclusion or limitation of

incidental or consequential damages, or limitations on how

long an implied warranty lasts, so the above exclusions or

limitations may not apply to you.

In no event shall recovery of any kind be greater than the

amount of the purchase price of the product sold. Alteration

of safety features of the product shall void this warranty.

You assume the risk and liability for loss, damage, or injury to

you and your property and/or to others and their property

arising out of the misuse or inability to use the product.

This limited warranty shall not extend to anyone other than the

original purchaser or to the person for whom it was purchased

as a gift.

HOW STATE LAW RELATES TO THIS WARRANTY: This

limited warranty gives you specific legal rights, and you may

also have other rights which vary from state to state.

IMPORTANT:

Owner must present Original Proof of

Purchase to obtain warranty coverage.
