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. 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. Lowering the tire pressure below the recommended pressure will change the pitch of the

deck which may require further deck pitch adjustment.

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.

6.2.1 Deck Adjustments

The mower deck can be adjusted for pitch and side-to-side levels. Pitch is the relationship between the

front of the deck and the rear of the deck in regards to height of cut. In most cases, a positive pitch (front of

the deck is lower than the rear of the deck) of ¼” is the optimum setting. The adjustments can easily be

made by using the threaded deck hangers (deck pitch and side-to-side adjustments) located at the front of

the deck and at the rear of the deck frame. These hangers are connected to the chains that hold the deck.

If you raise the lift rods above the 29” measurement, the deck may not raise all the way up into the

transport position. Be sure and check the deck height of cut range after any adjustments are made to the lift

rods or deck hangers to ensure that the height of cut adjustments work properly. If unable to make the

adjustments needed to align deck properly, contact your dealer for assistance.

First, ensure the Deck Lift Rod is 29” from center to

center of the ball ends, these rods MUST remain at the

29” center measurement.
