Internal
Neutral Adjustment
The neutral gate of the Tuff Torq K71, K66, K62, and K57
are established internally and should not need to be
adjusted. If the tractor creeps forward or backward with
the ground speed control pedals at rest (neutral position)
while the engine is running, perform the following adjust-
ment:
NOTE: The neutral adjustment hardware for all models
covered by this document is identical, and is also located
on the right side of the transmission.
1. Block the front tires.
2. Using an overhead chain hoist or hydraulic floor jack,
elevate the rear end of the tractor so that the wheels
do not contact the ground. Position jackstands under
the rear frame.
3. Using a 17 mm wrench loosen the neutral adjustment
jam nut (A, Figure 36).
4. Activate the seat switch, depress the brake pedal,
and start the engine.
5. Release the brake pedal.
6. Using an 8 mm wrench adjust neutral by turning the
eccentric (B) until the rear wheels do not creep.
7. Once neutral has been established, hold the eccentric
(B) in place and secure in position with the jam nut
(A).
8. Fully depress both the forward ground speed pedal
and reverse ground speed pedal and check that it
returns to neutral and the rear wheels do not creep.

Adjustment
1. Disengage the PTO, stop the engine, block the
wheels, remove the ignition key, and engage the
parking brake.
2. Remove the mower deck (see Mower Deck Removal).
3. Locate the brake spring (A, Figure 35) and adjust-
ment nut (B).
4. With the parking brake engaged, measure the com-
pressed spring length. The spring should be 2-1/2”
(6,4 cm) when compressed.
If the spring is not within this range, turn the adjust-
ment nut (B) to compress or release the spring.
