2. Remove the seat pan locknut as shown in FIG. 4. Tilt the seat forward. Temporarily
bypass the seat switch.
3. Loosen the front dampener ball stud nut as shown in FIG. 24. The dampener will be
adjusted and tightened after neutral is reset.
4. Staying clear of the rear drive tires, start the engine. If the EZT transmissions whine,
then the neutral setting needs to be re-adjusted.In this operation you will need to
adjust one side at a time. If either side whines significantly, then the steering lever
needs to be pushed into the operating position, disengaging the brake. Most likely
when the brake is disengaged, the drive wheel will begin to rotate even though the
steering lever is in the neutral position.
5. Shut off the machine. Loosen the jam nuts on each end of the pump control rod as
shown in FIG. 24.
6. Start the engine. Move the steering lever to just engage the brake (neutral) slot and
hold it in that position (Do not engage the steering lever far enough to engage the
brakes in the brake slot).
WARNING: This operation is extremely dangerous.
Pay close attention when adjusting
the pump control rod so you do not get your fingers, tools, or anything else close to the EZT pump
cooling fans.
7. While holding the steering lever position discussed in step 6,carefully adjust the pump
control rod until the rear wheel starts turning forward. Now turn the pump control rod in
the opposite direction until the moment when the wheel just stops turning forward.
Turn the control rod another 1/2 turn in this direction.Hold the pump rod in this position
and actuate the parking brake with steering lever. The EZT should not whine.
8. Hold the pump control rod still and turn off the engine.
9. Tighten the jam nuts on each end of the pump control rod.
NOTE: Do not let pump control rod turn while tightening the jam nuts.
10. Neutral is now set. Start the engine and actuate the brakes a few times to confirm that
the EZT does not whine when the park brake is set.
11. Repeat for the other side.
12. The steering dampener now needs to be adjusted and tightened.
13. Reconnect the seat switch and make sure the seat switch is operating properly per the
following procedure:
A. The operator must be on the seat when testing the seat switch.
B. Set both control levers in the park brake position.
C. Start the engine and allow it to warm up to operating temperature.
D. With the deck clutch switch down and the control levers in the park brake position, slowly raise off
of the seat. The engine should continue to run.
E. With the deck clutch switch up and/or the control levers in the neutral position, slowly raise off of
the seat. The engine should stop.
F. If the engine fails to stop when the deck clutch switch is up or one or both of the control levers are
not in the park brake position and the operator is off the seat, check the function of the seat switch.
If the seat switch is not operating properly (is not opening or closing) and if the cause can not be
