the hex nut securing the blade. See Fig. 7-7.

Transmission Drive Belt

Several components must be removed and special tools used in
order to change the tractor's transmission drive belt. See your
authorized dealer to have the transmission drive belt replaced.
Tractor Creeping
Creeping is the slight forward or backward movement of the
tractor when the engine is running at high idle and the drive
control levers are opened out in the neutral position.
If after operating the tractor for some time, it begins to creep
while in the neutral position, adjust the transmission control rods
as follows.
1. Place the front of the tractor against an immovable object
(e.g. wall, post, etc.).
2. Jack up the rear of the tractor so that both rear wheels are
approximately one inch of the ground.
3. With the engine running at high idle and the drive control
levers opened out in the neutral position, and the parking
brake disengaged, check the rear wheels for rotation.

Remove the flange lock nut and hex screw securing the
transmission control rod to the transmission control arm.
Wheel rotation should stop. If it does not, contact your
authorized service dealer.
If the rotation stops, adjust the control rod up or down as
necessary to align with the hole in the transmission control
arm. Re-insert the hex nut into the hole in the control arm
and secure with the hex lock nut.
If necessary, repeat the previous two steps to adjust the
other transmission control rod.
Lower the tractor and remove the jack.
