Parking Brake Adjustment

WARNING: Never attempt to adjust the brakes while the engine is running. Always disengage PTO, move speed control lever into neutral position, stop engine and remove key to prevent unintended starting.

If the tractor does not come to a complete stop when the brake pedal is completely depressed, or if the tractor’s rear wheels can roll with the parking brake applied (and the hydrostatic bypass rod pulled out), the brake is in need of adjustment. The brake disc can be found on the right side of the transmission in the rear of the tractor. Adjust if necessary as follows:

NOTE: A replacement cotter pin (part no. 714-0111) is needed to complete this adjustment. Have one on hand before proceeding.

Looking at the transmission from the right side of the tractor, locate the compression spring and brake disc. See Figure 18.

Figure 18

Carefully remove the cotter pin from the crown nut on the right side of the brake assembly.

Using a feeler gauge, check the gap between the brake disc and the brake puck. Proper gap is .011".

Tighten the crown nut until the proper gap is achieved.

Insert the replacement cotter pin into the crown nut.

Drag Link Adjustment

If the tractor turns tighter in one direction than the other, or if either the drag link and ball joint are being replaced due to damage or wear, the drag link may need to be adjusted. To do so, proceed as follows:

Place the steering wheel in position for straight- ahead travel.

Remove the lock nut which secures the ball joint to the steering arm. See Figure 19.

Lift the ball joint out of the steering arm and re- position both front tires for straight-ahead travel.

Loosen the jam nut (See Figure 19) and thread the ball joint either inward or outward until it aligns with the hole in the steering arm.

Confirm that both the steering wheel and the front tires are still positioned for straight-ahead travel before reinserting the ball joint into the steering arm and securing it with the lock nut removed earlier.

Re-tighten the jam nut loosened earlier.
