rules

when performing any mainte­

nance.

If tractor if-q-jiit-o more ih.m six (6) feet stopping distance

at high spec a in highest gear, then brake must be adjusted.

(See “TO ADJLiST BRAKE” in the Service and Adjust­

TIRES

Maintain proper air pressure in al! tires (See “PROD­

UCT SPECIFICATIONS” on page 3 of this manual).

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 flat tires due to
slow leaks, tire seaiant 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 systems are

working properly. If your tractor does not function as
described, repair the problem immediately.

The engine should not start unless the clutch/brake

pedal is fully depressed and attachement clutch control
is in the disengaged position.

When the engine is running, any attempt by the opera­
tor to leave the seat without first setting the parking

brake should shut off the engine.

When the engine is running and the attachment dutch

is engaged, any attempt by the operator to leave the

seat should shut oft 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. 10)

Raise mower to highest position to allow access to

blades.

Remove hex bolt, lockwasherandflatwashersecuring
blade.

Install new or resharpened blade with trailing edge up

towards deck as shown.

IMPORTANT:

TO ENSURE PROPER ASSEMBLY,

CENTER HOLE IN BLADE MUST ALIGN WITH STAR ON

MANDREL ASSEMBLY.

Reassemble hex bolt, lock washer and flat washer in

exact order as shown.

Tighten bolt securely (27-35 Ft. Lbs. torque).

IMPORTANT:

BLADE BOLT IS GRADE 8 HEATTREATED.

TO SHARPEN BLADE (See Fig. 11)

NOTE: We do not recommend sharpening blade - but if you

do, be sure the blade is balanced.

Care should be taken to keep

the

blade balanced. An

unbalanced blade will cause excessive vibration and even­

tual damage to mower and engine.

The blade can be sharpened with a file or on

a

grinding

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

ancer).

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.
