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 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.
6.2 Height-of-Cut
Before adjusting the height-of-cut be sure the mower blades are off, and the rear tires have proper air
pressure. Check for even tire wear. The height-of-cut can be adjusted the following way:
• The cut height is set by allowing the foot lever to rest on a detent pin
inserted into the height selection plates. To set the height of the pin,
raise the mower deck to the transport height position and lock in. This is
achieved by pressing the pedal all the way forward until the latch system
engages the pedal and locks the deck up in the transport position. With
the load removed from the detent pin, it can be changed to the desired
cut height. Once the pin is securely connected to the selector plate, the
deck can be lowered to the desired cutting height by pressing in on the
deck-lift foot pedal until the latch releases the pedal. Now the deck can
be lowered until it comes in contact with the pin.
6.2.1 Deck Lift Spring Assist Adjustment
To adjust the deck lift assist spring, raise the deck to the up and locked (transport) position. Remove spring
from the front spring attachment. Remove and reinstall in the upper hole (less tension) and lower hole (more
tension). Reinstall spring to front attachment.
6.2.2 Deck Adjustments
The mower deck can be adjusted for pitch and side-to-side levels. Pitch is the relationship between the front off
the blade and the rear of the blade in regards to the height of the cut. A positive pitch (front of the blade is
lower than the rear of the blade) of ¼” is the optimum setting.
Each of the four chain hangers connecting the mower deck to the lift assembly has an adjustable pivot plate
located on the top of the mower deck. On a flat and level surface, the pitch and side-to-side variation should be
checked regularly. Note: it is necessary to have a front to rear pitch of 1/4 inch aiming the front of the deck
toward the ground. Adjust one side at time when setting deck height adjustment.
If the deck is leaving stripes, it may be necessary to check the adjustment on the four deck hangers.
