18. Rotate the drive wheel release handle to the

“operating” position. Refer to the Drive Wheel

Release Valves section in Operation.

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

20. Remove jack stands.

Electric Clutch Adjustment

No adjustment necessary; however some later model year units have been built with clutches that contain a brake shim. When the clutch brake has worn to the point where the clutch no longer engages consistently, the shim can be removed to extend the clutch life.

Note: Do Not remove the brake pole from the field shell/armature. The brake pole has worn to match the armature and needs to continue to match after the shim is removed to ensure proper brake torque.

Removing the Shim:

1. Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake. Allow the machine to cool completely before starting these instructions.

2. Using a pneumatic line, blow out any debris from under the brake pole and around the brake spacers.

3. Check the condition of the wire harness leads, connectors, and terminals. Clean or repair as necessary.

4. Verify that 12V is present at the clutch connector when the PTO switch is engaged.

5. Measure the gap between the rotor and armature.

If the gap is greater than .04 inch (1 mm), proceed with the following steps:

A. Loosen both brake mounting bolts one-half to one full turn (see Figure 36).


Feeler gauge

B. Using needle nose pliers, or by hand, take hold of the tab and remove the shim (Do Not discard the shim until proper clutch function has been confirmed).

C. Using a pneumatic line, blow out any debris from under the brake pole and around the brake spacers.

D. Re-torque each bolt (M6 x 1) to 10 ft-lb (13

N-m) +/-0.5 ft-lb (0.7 N-m).

E. Using a 0.010 inch thick feeler gauge, verify that a gap is present between the rotor and armature face on both sides of the brake pole as shown. (Due to the way the rotor and armature faces wear (peaks and valleys) it is sometimes difficult to measure the true gap.)

Frequently Answers and Questions

What is the difference between the LAZER Z and other zero-turn mowers?
The LAZER Z is a commercial-grade mower that is built to last. It has a more powerful engine, a more durable deck, and a wider range of cutting widths than most other zero-turn mowers.
How do I choose the right cutting width for my needs?
The right cutting width for you depends on the size of your lawn. If you have a small lawn, a 42-inch cutting width will be sufficient. If you have a larger lawn, you may want to choose a 48-inch or 52-inch cutting width.
How do I maintain my LAZER Z mower?
The LAZER Z mower is easy to maintain. Simply follow the maintenance schedule in the owner's manual.
