WARNING
After getting the mower to track straight, readjust the neutral adjustment on the pump by using a ¼” allen
wrench at the Return-to-Neutral (RTN) mechanism, if necessary. It is normal to make these adjustments from
time to time.
5.9 How to Test/Use the Blade Clutch/Brake Switch
Before testing the blade clutch/brake operation, make sure the area is clear and there is nothing vulnerable to
thrown objects from under the mower. No one should be near the mower deck or in its line of discharge. The
discharge chute deflector should be in the down position. Move the engine throttle to ¾ speed setting. When
mowing, the engine speed should always be at its highest setting. The engine governor will regulate the
engine according to the different mowing conditions at that setting. Sit evenly on seat and keep both feet firmly
on the foot platform and turn on the blade clutch switch. Run blades for a minute or so. Try engaging and
disengaging the blades a few times about 10 seconds apart. If the blades do not start and stop in a few
seconds each time, service the blade brake system or contact your local Wright dealer. Under mowing load,
the clutch’s life will be the greatest if engaged and disengaged at the ¾ throttle level.
5.10 How to Test the Operator Presence Control (OPC) Switch
With blades ON, try lifting your weight off the seat to test the Operator Presence Control switch (OPC). The
engine should begin to kill after a ½ second delay and the blades should stop within a few seconds. If not,
service the OPC system or contact your local Wright dealer.
6 SERVICE AND ADJUSTMENTS
6.1 Tire Maintenance and Pressure
Excessively worn tire tread is dangerous on all hills. Replace drive tires with less than 3/32” of any tread
groove left. Use tires with the tread pattern recommended by Wright Mfg., Inc. only. Keep the tire pressure
in the drive tires between 18 and 22 psi. Lowering tire pressure will affect deck pitch. Always check pitch
any time tire pressure is set below recommended pressures. Higher pressures will cause the tires to have
less traction, which will force you to go slower and with less safety and give you a harder ride. The front
casters are equipped with non-pneumatic tires and do not require any air. They do not have any tread but
should be replaced when excessively worn.
