Maintenance

CAUTION

Raising the mower deck for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous. The mechanical or hydraulic jacks may not be enough support or may malfunction allowing the unit to fall, which could cause injury.

Do Not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands or equivalent support.

5.Remove the rear tires from the machine.

6.Remove any debris from the brake area.

7.Rotate the drive wheel release handle to the “released” position. Refer to the Drive Wheel Release Valves section in Operation.

8.Disengage the park brake.

9.Hold the threaded rod end with a tool and loosen the lock nut away from the standard nut (see Figure 31). Do Not allow the cable to turn when the nuts are being loosened.

6.Lock nut

10.Remove all slack from cable by pulling on the caliper lever arm with a medium amount of force. Using hands and fingers only, push the caliper lever arm to engage the brake pads on the rotor until the lever stops. While holding the lever

at the stopped position, use the other hand or fingers to pull the slack out of the cable threaded end through the swivel. Spin the standard nut against the swivel (see Figure 31).

Note the order of the standard nut and lock nut (no nut on the cable anchor side of the swivel).

11.Release the caliper lever and cable. Turn the wheel hub by hand in both directions relative to the caliper; slight drag of the caliper pad on the wheel hub is desired.

12.If there is no movement between the hub and the caliper then back off the standard nut one turn from the swivel and repeat step 11 (drive release valves must be in the “released” position on the hydros).

13.If the hub moves very freely relative to the caliper, then tighten the standard nut one turn against the swivel and repeat step 11.

14.Once step 11 is achieved, hold the threaded rod end with a tool and tighten the lock nut against the standard nut. Do Not allow the cable to turn when the nuts are tightened.

15.After adjusting the brakes on both sides of the mower, cycle the brake handle a minimum of six times to allow the cable to seat into the sheath and mounting tabs.

16.Readjust both brakes following the procedure in steps 10 through 14.

17.If a brake component has been removed or replaced, see the steps below; otherwise proceed to step 18.

Burnishing the Brake Procedure:

A.Clear the area of any flammable material before starting the burnishing process.

B.Rotate the drive wheel release handle to the “operating” position. Refer to the Drive Wheel Release Valves section in Operation.

C.Apply the park brake.

D.Install a 1/2 x 6 inch (approx.) rod or bolt through the 2 inch height of cut hole (see Figure 32).
