• Disengage all attachment clutches, thoroughlydepress the brake pedal, and shift into neutralbefore attempting to start engine.

• Your mower is designed to cut normal residential

grass of a height no more than 10". Do not attemptto mow through unusually tall, dry grass (e.g.,

pasture) or piles of dry leaves. Debris may build upon the mower deck or contact the engine exhaust

presenting a potential fire hazard.

2. 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 theslope or if you feel uneasy on it, do not mow it.For your safety, use the slope gauge included as part of thismanual to measure slopes before operating this unit on asloped or hilly area. If the slope is greater than 15° asshown on the slope gauge, do not operate this unit on thatarea or serious injury could result.

DO:

• Mow up and down slopes, not across.

• Remove obstacles such as rocks, limbs, etc.

• Watch for holes, ruts or bumps. Uneven terraincould overturn the machine. Tall grass can hideobstacles.

• Use slow speed. Always keep machine in gearwhen going down slopes to take advantage ofengine braking action.

• Follow the manufacturer's recommendations for

wheel weights or counterweights to improvestability.

• Use extra care with grass catchers or other

attachments. These can change the stability of themachine.

• Keep all movement on the slopes slow andgradual. Do not make sudden changes in speed ordirection. Rapid engagement or braking couldcause the front of the machine to lift and rapidly flipover backwards which could cause serious injury.

• Avoid starting or stopping on a slope. If tires losetraction, disengage the blade(s) and proceed slowlystraight down the slope.

DO NOT:

• Do not turn on slopes unless necessary; then, turnslowly and gradually downhill, if possible.

• Do not mow near drop-offs, ditches orembankments. The mower could suddenly turnover if a wheel is over the edge of a cliff or ditch, orif an edge caves in.

• Keep children out of the mowing area and inwatchfulcare of an adult otherthan the operator.

• Be alert and turn machine off if children enter the

area.

• Before and when backing, look behind and downfor small children.

• Never carry children, even with the blades off. Theymay fall off and be seriously injured or interfere withthe safe machine operation.

• Never allow children under 14 years old to operatethe machine. Children 14 years and over shouldonly operate machine under close parental

supervision and proper instruction.

• Remove key when machine is unattended toprevent unauthorized operation.

MOWING

This tractor is equipped with one of MT_s highquality cutting decks. The following information willbe helpful when using the cutting deck with yourtractor.

WARNING: To avoid possible injury, donot allow anyone in the area of the tractorwhile mowing. Even if the area to bemowed has been cleared of foreignobjects, small objects may be picked upand discharged by the mower.

,_ WARNING: Never direct the dischargeof material toward bystanders or allowanyone near the machine while inoperation.

• For best results it is recommended that the

first two laps be cut with the discharge throwntowards the center. After the first two laps,reverse the direction to throw the discharge tothe outside for the balance of cutting. This willgive a better appearance to the lawn.

Do not cut the grass too short. Short grassinvites weed growth and yellows quickly in dryweather.

• Mowing should always be done with theengine at full throttle.

• Do not mow at high ground speed, especiallyif a mulch kit or grass collector is installed.

• Under heavier conditions it may be necessaryto go back over the cut area a second time toget a clean cut.

• Do NOT attempt to mow heavy brush andweeds and extremely tall grass. Your tractor isdesigned to mow lawns, NOT clear brush.

• Keep the blades sharp and replace the bladeswhen worn. Refer to the MAINTENANCE

section of this manual for proper bladesharpening instructions.
