lengthening the right-side rod) or the left side needs to go slower (by shortening the left-side rod). It is
important that neither rod should be lengthened too far, as mentioned above.
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. The parking brake should now be applied.
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 the parking brake applied and the 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. WARNING
