OLD ONES ARE WORN, BROKEN, OR BENT.
After getting the mower to track straight,
readjust the neutral adjustment , if 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 setting. (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 life 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 30 and 40 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. 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 lever. 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 ¼” 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 connected to the chains that hold
the deck. Simply rotate the hanger at the
corner of the deck that needs adjustment.
These hangers 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 ensure that the
height of cut adjustments work properly. If
unable to make the adjustments needed by only
using these hangers, contact your dealer for
assistance.
WARNING
Belt Tension Adjustment
The pump drive belt is self-adjusting, and
requires no adjustment, just replacement. The
