Section 4 - ADJUSTMENT & REPAIR
WARNING
DO NOT attempt any adjustments, maintenance or
service with the engine or blades running. STOP
blades. STOP engine. Set brake. Remove key.

4.3 TRACTOR DRIVE COMPONENTS
4.3.1. BRAKE ADJUSTMENT
When adjusted properly, the brake should stop the
tractor in approximately 6 feet or less from top speed.
Drive the machine at maximum forward speed and
apply the brake. If stopping distance is greater than 6
feet, brake adjustment is required.
1. Turn engine “OFF”. Remove key.
2. Locate brake adjustment nut underneath the left
side at the rear of tractor. See Figure 4.9.
3. Turn nut 1 turn clockwise to increase braking
action. DO NOT over tighten brake adjustment.
4. Start engine and test brake.
5. Continue adjustment as described above until
proper brake function is achieved.

4.3.2. STEERING ADJUSTMENT

adjust as follows:
1. Turn engine “OFF”. Remove key.
2. From left side of tractor, locate the steering sector
below fuel tank. See Figure 4.10.

3. Loosen the eccentric mounting nut and rotate the
eccentric clockwise until steering “Play” is reduced.
See Figure 4.10.
4. Tighten eccentric mounting nut.
4.3.3. SHIFTER ADJUSTMENT
The shift linkage is set at the factory and should not
require further adjustment. The shifter is adjusted
properly when the speed control lever can be placed
at rear edge of the neutral detent and the tractor
remains absolutely stationary. If motion is detected,
neutral adjustment will be required. DO NOT operate
a machine that creeps when shifted to neutral.
1. Stop engine. Remove key.
2. Move speed control lever to rear edge of neutral
detent and hold firmly.
3. Locate neutral adjustment nut underneath the
right rear of the tractor. See Figure 4.11.
