Z Master® 4000 Series Riding Mower

Before starting the machine each day, perform the Each Use/Daily procedures listed in .

New engines take time to develop full power. Mower decks and drive systems have higher friction when new, placing additional load on the engine. Allow 40 to 50 hours of break-in time for new machines to develop full power and best performance.

The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable (Figure 12).

Figure 12

The MyRide™ suspension system adjusts to provide a smooth and comfortable ride. You can adjust the rear 2-shock assemblies to quickly and easily change the suspension system. Position the suspension system where you are most comfortable.

The slots for the rear-shock assemblies have detent positions for reference. You can position the rear-shock assemblies anywhere in the slot, not just in the detent positions. The following graphic shows the position for a soft or firm ride and the different detent positions (Figure 13).

The drive wheels turn independently, powered by hydraulic motors on each axle. You can turn 1 side in reverse while you turn the other forward, causing the machine to spin rather than turn. This greatly improves the machine maneuverability but may require some time for you to adapt to how it moves.

The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the FAST position for best performance. Always operate in the full throttle position when mowing.

The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf.

9. Pack the bearings with a general-purpose grease.

10. Insert 1 bearing and 1 new seal into the wheel.

11. If the axle assembly is missing both spacer nuts, apply a thread-locking compound to 1 spacer nut and thread it onto the axle with the wrench flats facing outward.

    Note: Do not thread the spacer nut all of the way onto the end of the axle. Leave approximately 3 mm (1/8 inch) from the outer surface of the spacer nut to the end of the axle inside the nut.

12. Insert the assembled nut and axle into the wheel on the side with the new seal and bearing.

13. With the open end of the wheel facing up, fill the area inside the wheel around the axle full of general-purpose grease.

14. Insert the second bearing and new seal into the wheel.

15. Apply a thread-locking compound to the second spacer nut, and thread it onto the axle with the wrench flats facing outward.

16. Torque the nut to 8 to 9 N∙m (75 to 80 in-lb), loosen the nut, then torque it to 2 to 3 N∙m (20 to 25 in-lb).

    Note: Make sure that the axle does not extend beyond either nut.

17. Install the seal guards over the wheel hub, and insert the wheel into the caster fork.

18. Install the caster bolt and tighten the nut fully.

Important: To prevent seal and bearing damage, check the bearing adjustment often. Spin the caster tire. The tire should not spin freely (more than 1 or 2 revolutions) or have any side play. If the wheel spins freely, adjust the torque on the spacer nut until there is a slight amount of drag. Apply another layer of thread-locking compound.

Note: Service the air cleaner more frequently if operating conditions are extremely dusty or sandy.

Ensure that the air gap between the center and side electrodes is correct before installing the spark plug. Use a spark plug wrench for removing and installing the spark plug and a gapping tool or feeler gauge to check and adjust the air gap. Install a new spark plug if necessary.

Type of Spark Plug:

Kawasaki FX691 and FX801 engines—NGK^® BPR4ES or equivalent

Air Gap: 0.75 mm (0.030 inch)

Checking the Spark Plug(s)

Important: Do not clean the spark plug(s). Always replace the spark plug(s) when it has a black coating, worn electrodes, an oily film, or cracks.

If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty.
