MAINTENANCE

TRACTOR

Always observe safety rules when performing any main-

te nance.

BRAKE OPERATION

If tractor requires more than ﬁ ve (5) feet to stop at highest

speed in highest gear on a level, dry concrete or paved

surface, then brake must be checked and adjusted, then

brake must be adjusted. (See “TO ADJUST BRAKE” in the

Service and Adjustments section of this manual).

TIRES

• Maintain proper air pressure in all tires (See “PROD UCT

SPECIFICATIONS” section of this man ual).

• Keep tires free of gasoline, oil, or insect control chemi-

cals which can harm rubber.

• Avoid stumps, stones, deep ruts, sharp objects and

other hazards that may cause tire damage.

NOTE: To seal tire punctures and prevent ﬂ at tires due to

slow leaks, tire sealant may be purchased from your local

parts dealer. Tire sealant also prevents tire dry rot and

corrosion.

OPERATOR PRESENCE SYSTEM

Be sure operator presence and interlock sys tems are work-

ing properly. If your tractor does not function as described,

repair the problem immediately.

• The engine should not start unless the brake pedal is

fully depressed and attachement clutch control is in

the disengaged position.

• When the engine is running, any attempt by the op er a tor

to leave the seat without ﬁ rst setting the parking brake

should shut off the engine.

• When the engine is running and the at tach ment clutch

is engaged, any attempt by the operator to leave the

seat should shut off the engine.

• The attachment clutch should never operate unless

the operator is in the seat.

BLADE CARE

For best results mower blades must be kept sharp. Re place

bent or damaged blades.

BLADE REMOVAL (See Fig. 13)

• Raise mower to highest position to allow access to

blades.

NOTE: Protect your hands with gloves and/or wrap blade

with heavy cloth.

• Remove blade bolt by turning counterclockwise.

• Install new or resharpened blade with stamped "THIS

SIDE UP" facing deck and mandrel assembly.

IMPORTANT: TO ENSURE PROPER ASSEMBLY, CENTER

HOLE IN BLADE MUST ALIGN WITH STAR ON MANDREL

ASSEMBLY.

• Install and tighten blade bolt securely (45-55 Ft. Lbs.

torque).

IMPORTANT: SPECIAL BLADE BOLT HEAT TREATED.

BATTERY

Your tractor has a battery charging system which is suf ﬁ cient

for normal use. However, periodic charging of the battery

with an automotive charger will extend its life.

• Keep battery and terminals clean.

• Keep battery bolts tight.

• Keep small vent holes open.

• Recharge at 6-10 amperes for 1 hour.

NOTE: The original equipment battery on your tractor is

maintenance free. Do not attempt to open or remove caps

or covers. Adding or checking level of electrolyte is not

nec es sary.

TO CLEAN BATTERY AND TERMINALS

Corrosion and dirt on the battery and terminals can cause

the battery to “leak” power.

TO SHARPEN BLADE (See Fig. 14)

NOTE: We do not recommend sharp en ing blade - but if

you do, be sure the blade is balanced.

Care should be taken to keep the blade balanced. An un-

balanced blade will cause excessive vibration and even tual

damage to mower and engine.

• The blade can be sharpened with a ﬁ le or on a grind-

ing wheel. Do not attempt to sharpen while on the

mower.

• To check blade balance, you will need a 5/8" diameter

steel bolt, pin, or a cone balancer. (When using a

cone balancer, follow the instructions supplied with

bal anc er.)

NOTE: Do not use a nail for balancing blade. The lobes of

the center hole may appear to be centered, but are not.

• Slide blade on to an unthreaded portion of the steel bolt

or pin and hold the bolt or pin parallel with the ground.

If blade is balanced, it should remain in a horizontal

position. If either end of the blade moves downward,

sharpen the heavy end until the blade is balanced.
