5 Service and Adjustments 

 

5.1 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.

 

 

5.2 Height-of-Cut 

Before Adjusting the Height-of-Cut be sure of proper air pressure in rear drive tires and check for even tire 
wear.  Your mower is set from the factory at 3” with a ¼” forward pitch.  The height-of-cut can be adjusted the 
following ways: 

 

1.  Coarse Adjustment:  For the coarse adjustment (1/2 inch increments) the rear motor supports 

(A) and (1 inch increments) front caster arms (B) need to be adjusted up or down to achieve a 
1.5”-5” deck height. 

2.  Fine Adjustments: For fine adjustments (1/16”-1/4”) adjust either the ¼” blade spacers, ¼” 

caster “C” spacers (C) or 1/16” caster washer (D).   

3.  Temporary Height-of-Cut Adjustment: using the caster shims ("C" spacers) you can adjust the 

blades downward 

 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

 
 

 

 
 
*Blade spacers can be added or removed for additional adjustment in ¼” increments.  Use three blade 
spacers for optimum cut. 
*For optimal deck pitch use one caster spacer.  Always keep the 1/16” washers above the “C” spacers to 
prevent the spacers from sliding off of the caster pin. 

 

The angle of attack of the blades should always be lower at the front. This makes the blade cut the grass 
only once and saves fuel and wear on the whole mower. It also allows more efficient mowing and grass 
catching or dispersal. If you mow in an area of the country where the lawn is very thick and spongy you may 
have to set these two adjustments as they would appear on the grass and not on a hard surface due to the 
tires “floating” up on or “sinking” down into the lawn.
