necessary. It is normal to need to make these
adjustments from time to time as the linkage
breaks in or wears.
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. The
parking brake should now be applied. Move the
engine throttle to the highest RPM speed set-
ting. (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.)
Place 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 longevity will be the greatest at
the highest RPM setting.
How to Test the Operator Presence
Control (OPC) Switch
With the parking brakes applied and the blades
ON, try lifting your feet off the foot platform to test
the Operator Presence Control switch (OPC).
The engine should kill and the blades should stop
within a few seconds. If not, service the OPC
system or contact your local Wright dealer.
Service and Adjustments
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. Keep the tire pressure in
the front caster tires between 20 and 35 psi.
Higher pressures will help keep the caster tires
on their rims when impacted from the side but
give a harder ride. They do not have any tread but
should be replaced when excessively worn.
Height-of-Cut
Before Adjusting the Height-of-Cut be sure the
mower deck is off, and all four tires have proper
air pressure and 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 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 hand side and then lower the lever
towards the front of the machine until it stops
at the set height of cut.
Deck adjustments
The mower deck can be adjusted for pitch and
side-to-side level. 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 lower than the
rear of the deck) of 1/4" is the optimum setting.
These two adjustments can easily be made by
using the threaded deck hangers located at each
corner of the deck. These hangers are con-
nected to the chains that hold the deck. Simply
rotate the hanger of the corner of the deck that
needs adjustment. These hanger are right-
handed threads. If you raise the rear hangers
above the factory setting, the deck may not raise
all the way up into transport position. Be sure
and check the deck height of cut range after any
adjustments are made to these hangers to insure
that the height of cut adjustments work properly. If
you are unable to make the adjustments needed
by only using these hangers contact your dealer
for assistance.
