Section 4 - ADJUSTMENT & REPAIR
4.3TRACTOR DRIVE COMPONENTS 4.3.1. BRAKE ADJUSTMENT
1.To be properly adjusted, the brake should stop the tractor in approximately 6 feet from top speed when the clutch/brake pedal is fully depressed.
2.Adjust brake when necessary as follows:
3.Turn engine “OFF”. Remove key.
4.Locate brake adjustment nut underneath the rear of tractor. See Figure 4.13.
5.Turn nut clockwise to increase braking action or counterclockwise to decrease braking action.
6.Start engine and test brake.
7.Continue adjustment as described above until proper adjustment is achieved.

WARNING
DO NOT attempt any adjustments, maintenance or service with the engine or blade running. STOP blade. STOP engine. Set brake. Remove key. Remove spark plug wire from spark plug and secure wire away from spark plug. Engine and components can be extremely hot. Avoid burns by allowing engine and components sufficient time to cool.
4.3.2STEERING ADJUSTMENT
Should excessive “Play” be noted in the steering, adjust as follows:
1.Turn engine “OFF”. Remove key.
2.From left side of tractor, locate the steering sector below fuel tank. See Figure 4.14.

3.Loosen the eccentric mounting nut and rotate the eccentric clockwise until steering “Play” is reduced. Refer back to Figure 4.14.
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 4.15
4.Turn the neutral adjustment nut 1/4 turn clockwise to reduce FORWARD creep. Turn the adjustment nut 1/4 turn counter clockwise to reduce Reverse creep. Only turn the adjustment nut in 1/4 turn increments.
5.Check for creep in neutral. Start engine. Move speed control lever to rear edge of the neutral detent. Machine should not move. If further adjustment is required, stop engine and repeat Step 4.
WARNING
DO NOT adjust shift linkage with engine running. The adjustment requires hands to be close to rotating parts. STOP engine. REMOVE key.
