Troubleshooting, Adjustments, & Service

PARKING BRAKE ADJUSTMENT

Brake Adjustment

1.Disengage the PTO, stop the engine, block the front wheels, remove the ignition key, and lock the motion control levers into their neutral lock positions.

2.Elevate the rear end of the unit, making sure it is safely supported.

3.Before attempting brake adjustment, check the brake gear (A, Figure 23a), brake arm (B), park brake bracket (D), brake rod (E), and compression spring

(F) for dirt or debris that may affect brake operation.

4.Check to see that the brake arms (B) are engaged against the brake gears (A), with the teeth on the arms meshing with the teeth on the gears.

Note: The rear wheels may need to be moved slightly for the teeth to mesh properly.

5.With the parking brake disengaged (motion control levers moved from their neutral locked positions), measure the length of the compression spring (F). The measurement should be between 2-1/2” and 2- 3/4”. If not, tighten or loosen the brake rod adjust- ment nut (C) until the correct measurement is achieved.

FRONT SUSPENSION ADJUSTMENT (SELECT MODELS)

The shock assembly can be adjusted to vary the amount of pre-load applied to the springs. This allows the opera- tor to customize the ride according to operator’s weight and operating conditions.

LESS PRE-LOAD:

Light operator weight

Softer, more cushioned ride

Best for relatively flat terrain

MORE PRE-LOAD:

Heavy operator weight

Stiffer, more rigid ride

Better handling and greater stability on hilly terrain

TO ADJUST THE SPRING PRE-LOAD:

1.Park machine on a flat, level surface. Disengage the PTO, stop the engine and engage the parking brake.
