WARNING
The wheels should now go to a neutral position if the steering control levers are locked using the
thumb locks and/or the speed control lever is in neutral.
5.8 Straight Line Tracking Adjustments
Verify that both rear tires are inflated to the proper PSI.
Find a wide open flat area away from bystanders and objects.
Drive the mower with the speed control set to the most used position.
If the mower pulls to one side, return the speed control lever to neutral and shut off the engine.
If the mower pulled to the left, turn the tracking adjustment knob counterclockwise (left) ½ turn.
Repeat driving the mower and making incremental adjustments after shutting the engine off until the
mower tracks straight.
Conversely, if the mower pulls right, turn the tracking adjustment knob clockwise (right).
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 the highest RPM 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.) Engage the OPC switch 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 longevity will be the greatest at the
highest RPM setting.
5.10 How to Test the Operator Presence Control (OPC) Switch
Before beginning this test, secure a large open area that is free of obstacles or hazards.
To test the OPC switch start the engine using the normal starting procedures, release the parking
brake and place the speed control in the slowest speed setting. While engaging the OPC lever(s)
engage the blades by pulling up on the PTO blade clutch switch. Allow the mower to start moving
forward and then release the mower handles. If the engine doesn’t stop, then service the OPC
system.
