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.Engage the parking brake (lever up).

8.Loosen the jam nut (item 9 in Figure 22) just above the trunnion roller 2-3 turns.

9.Tighten the bottom nyloc nut (item 3 in Figure 22) until the brake spring is completely compressed, then loosen one-half turn.

10.Tighten the jam nut against the trunnion roller

11.Check the clearance between the bottom of the brake bracket and the nyloc nut just under the

spring. Clearance should measure 1/8 to 3/16 inch (3.2-4.8 mm). If necessary, adjust the nyloc nut accordingly.

12.If the correct gap can no longer be achieved because there is no clearance between the nyloc nut below the spring and the jam nut, or there are no threads left in the bottom nyloc nut, the length of the brake rod can be adjusted. Remove a pin from a yoke at either end of the brake rod and lengthen (or shorten) the brake rod until the correct gap can be achieved.

13.If a brake component has been removed or replaced, see the steps below; otherwise proceed to step 14.

Burnishing the Brake Procedure:

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

B.While sitting in the operator’s seat, start the engine, and release the park brake.

WARNING

Engine must be running and drive wheels must be turning so adjustments can be performed. Contact with moving parts or hot surfaces may cause personal injury.

Keep fingers, hands, and clothing clear of rotating components and hot surfaces.

C.Increase the throttle to high idle.

D.Bring both drive levers out of neutral and push them into full forward position.

E.Pull the park brake lever up until the engine rpm starts to drop. Hold the park brake lever in this position for 15 seconds.

F.Release the brake lever.

G.Move the drive levers into the full reverse position. Repeat steps E and F.

H.Move the drive levers back to the neutral lock position.

I.Return the throttle to low idle, and stop the engine.

J.Allow the brake bands and drums to cool. Repeat steps 7 through 11.

14.Install the tires and torque the lug nuts to 90-95 ft-lb (122-129 N-m).

15.Remove the jack stands.
