5.8 How to Perform the Tracking Adjustment
First ensure that the tire pressure is equal on both rear drive tires (18-22 psi). Drive the mower on a level
parking lot with the engine at full throttle. Check that the mower drives in a straight line when both hand
controls are held to the full speed position. If not, park the mower and stop the engine. The adjustment is
made by loosening the jam-nuts on the control rods (Fig. 1, at transaxle) (Fig.2, at control handle) (this may
need to be done to one or both control rods) and adjusting the control rods. Once the jam-nuts are loosened at
the front and rear of the control rod proceed to turning the control rod clockwise or counter-clockwise to
lengthen or shorten the effective length of the control rod.
If the rod is made longer it will increase the forward speed capability for that side of the mower and if the rod is
made shorter it will slow down that side of the mower. Therefore, if the mower is tracking to the left, either the
left side needs to go faster (by lengthening the left-side rod) or the right side needs to go slower (by shortening
the right-side rod). If the mower is tracking to the right, either the right side needs to go faster (by 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. 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 3-6 second delay and the blades should stop within a few seconds. If not,
service the OPC system or contact your local Wright dealer.
