WARNING
extremely off either because you are installing new parts or other reasons you should only use the faster
Speed/ Sensitivity setting to get the tracking to be accurate. After getting the mower to track straight, readjust
the neutral adjustment, if necessary. It is normal to need to make these adjustments from time to time as the
linkage breaks in or wears.
5.10 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.) Place 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 within 6-9 seconds each time, inspect the clutch or contact your local Wright
dealer. Under mowing load, the clutch’s life will be the greatest at the highest RPM setting.
5.11 How to Test the Operator Presence Control (OPC) Switch
With the parking brakes applied and the blades ON, try lifting your feet
off the foot platform to test the Operator Presence Control switch (OPC).
The engine should kill and the blades should stop within 6-9 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 24 psi. 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. Front Casters are equipped with
non-pneumatic tires and do not required any air. They do not have any tread but should be replaced when
excessively worn.
6.2 Height of Cut
Before adjusting the height-of-cut be sure the mower blades are not spinning,
and rear tires have proper air pressure. Check for even tire wear. The height-
of-cut can be adjusted the following ways:
• Pull the deck lift lever on the right hand side of the mower towards the rear of
the mower until it clicks once into the locked transport position. Then set the
mower blade height with the selector pin on the left hand side of the mower.
Once the proper height setting is set on the left, pull back on the deck lift
lever on the right hand side and then lower the lever towards the front of the
machine until it stops at the set height of cut.
