WARNING
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 both
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
side and then lower the lever towards the front of the machine until it
stops at the set height-of-cut.
6.3 Belt Tension Adjustment
The pump drive belt is self-adjusting, and requires no adjustment, just replacement. The blade drive belt
is self-adjusting also and requires no adjustment, just replacement.
