Maintenance

12.Re-measure until all four sides are the correct height. Tighten all the jam nuts on the deck lift arm assemblies.

13.Lower discharge deflector.

14.If the four deck links do not have enough adjustment to achieve accurate cut height with the desired rake, the single point adjustment can be utilized to gain more adjustment (see Figure 30).

2.Front height-of-cut plate mounting bolt

3.Rear height-of-cut plate mounting bolt

15.To adjust the single point system, first loosen the front and rear height-of-cut plate mounting bolts.

16.If the deck is too low, tighten the single point adjustment bolt by rotating it clockwise. If the deck is too high, loosen the single point adjustment bolt by rotating it counterclockwise.

Note: Loosen or tighten the single point adjustment bolt enough to move the height-of-cut plate mounting bolts at least 1/3 the length of the available travel in their slots. This will regain some up and down adjustment on each of the four deck links.

17.Re-tighten front and rear height-of-cut plate mounting bolts.

Important: Torque the front and rear height-of-cut plate mounting bolts to 27-33 ft-lb (37-45 N-m).

18.Repeat steps 9 through 13.

Adjusting the Parking Brake

Service Interval: After the first 100 hours Every 500 hours thereafter

Check to make sure brake is adjusted properly. This procedure must be followed after the first 100 hours or when a brake component has been removed or replaced.

1.Drive the machine onto a level surface.

2.Disengage the blade control switch (PTO), move the motion control levers to the neutral locked position and set the parking brake.

3.Stop the engine, wait for all moving parts to stop, and remove the key.

4.Raise the back of the machine up and support the machine with jack stands.

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.Measure the overall length of the compression spring. The correct length should be between

1 1/2–1 9/16 inches (3.8–4.0 cm). If the spring length is within this range, no adjustment is needed. If it is not, proceed to step 9.

9.Hold the threaded rod end with a tool and adjust the lock nut until the spring length is between

1 1/2–1 9/16 inches (3.8–4.0 cm) see Figure 31).
