PRE-DELIVERY SERVICE OF MOWER BY DEALER
The Wright Mower is shipped completely assembled and has been adjusted and tested at the factory.
However, due to the jostling of the shipping process and the delivery time lapse, the following items
need to be repeated again before starting the mower. After you have uncrated the mower, follow these
procedures in the order indicated:
xRemove spark plug wire from spark plug(s).
xInspect the mower for any damage, unusual conditions or missing parts.
xInspect the mower for all of its decals, especially the warning decals. There should be one blade
warning decal on each side of the deck, the “shield missing” decal under the blade belt cover, and
the dash decal.
x Check to ensure belt guard is in place before operation.
xCheck (and fill if necessary) engine oil level according to the engine manufacturer’s recommendation.
xCheck (and fill if necessary) hydraulic fluid level. Use fully SYNTHETIC oil: Mobil-1 15W-50.
xCheck tire pressures. Adjust to recommended pressure. It should be even on both sides but the
recommended pressures are generally different for the front and rear tires.
xRemove the blade belt cover and check (adjust if necessary) all belt tensions according to
specifications in Owners Manual. DO NOT OVERTIGHTEN.
xRotate the blade pulleys slightly to see if they all turn together. (Note: Clutch Brake will create some
resistance.)
xLubricate all appropriate moving parts
xReinstall the blade belt cover.
xRemove battery (if electric start version) from machine and fully charge (if necessary) in an open,
well-ventilated area according to the recommendations of the battery charger manual. The battery
is 12 volts. After fully charged, install on mower and attach battery cables, positive first (from
starter motor) and negative last (from ground).
xFill fuel tank with regular unleaded gasoline. Open fuel valve located between fuel tank and engine.
xDO NOT START THE ENGINE AT THIS TIME. FOLLOW THE NEXT PROCEDURE BEFORE
STARTING. The hydraulic system MUST be checked for proper operation before allowing wheels
to operate on the ground.
xSet the rear of the machine on jack stands or blocks to raise rear wheels off the ground two or three
inches and check to be sure that the mower will not fall off the supports you devise. The stand(s)
must be able to secure the mower from rolling off or away during the next procedures. Check
under the mower deck for any debris or unusual conditions.
xWith hand controls and speed control in the neutral position, apply the parking brake.
xOpen the manual bypass valve on top of each pump a half-of-a-turn counterclockwise.
xReattach spark plug wires to spark plugs.
xBefore starting the engine, be ready to stop it if the wheels begin to turn with the brake on. (If this
happens, check that the manual bypass valve on top of each motor are open at least a half-of-a-
turn counterclockwise.)
xStart the engine according to the engine manufacturer’s recommendation. Let the engine run at low
RPM for several minutes to get the hydraulic fluid circulating through the pumps, etc. Release the
parking brake. Now gradually close the manual bypass valve on top of each pump one at a time,
and see if the wheels start to move. If the wheels move when the hand controls are in neutral
position, adjust the neutral adjustment allen screw located on each pump until they stop (use the
neutral adjust knob for older mowers). The manual bypass valve on top of each pump should now
be firmly closed. Now try moving the hand control levers, one at a time, to make the wheels move
in forward and backward rotation. Check to see if the wheels move forward and backward
according to position of the levers. If not, service the hand control system. If the wheels stop when
the hand controls are in the neutral position the parking brake should now be applied. Now check
4

if the parking brake locking system (if applicable) prevents the unit from being driven while
engaged. If not, service the parking brake locking system.
xBefore testing the blade clutch/brake operation, make sure the area is clear and there is nothing
vulnerable to possible thrown objects from under the mower. No one should be near the mower
deck or in its line of discharge at this or at any time. The discharge chute deflector should be in
the down position. Move the engine throttle control to its highest RPM speed setting.
xTurn 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. With the blades on, now try disengaging the OPC
switch to test the Operator Presence Control switch (OPC). The engine should die and the blades
should stop in several seconds. If not, service the OPC system. Try this a couple of times.
xDisengage the blades, shut off the engine and remove the mower from the stand(s).
xDrive the mower around on a level parking lot. It is recommended that the slower setting of the Speed
Adjustment be used. (See further in this manual for information on Speed Adjustment.) Check that
the mower drives in a straight line when both hand controls are at the full speed position. If not,
see further in this manual for information on tracking adjustment.
xAs you drive the mower, listen for any unusual noises and test for irregular operation and adjust or
service as necessary. Next, go over the safety information and operating procedures in this
manual with the customer. Instruct the customer in proper operation and observe the customer
during their initial operation on a level parking lot. Make sure the customer is familiar and
comfortable with the basic operation and use of the mower.
xDealer: Register the mower online. If unable to use the online registration process then follow
the instructions on the Product Registration Form and have the customer fill out his part of
the form. After the Product Registration Form is filled out and signed by the customer and
a representative from your dealership, please mail or fax it immediately (within 30 days
from date of retail purchase) to your Wright Commercial Products Distributor according to
the directions on the Form. Then give the customer his copy of the registration form and
then keep your copy and mail the remaining copies of the form to your Wright
Manufacturing Products Distributor. The limited warranty is not valid unless the mower is
registered and all of the above steps are taken. Remember, the purchaser is both your and
our customer and his satisfaction is very important. Thank you for supporting our
products.
xThe mower is now ready for delivery to your customer.

REMOVING HYDRAULIC OIL COOLER ON
SPORT and RH MOWERS
*** PRODUCT RECALL ***
Subject: Removal of hydraulic oil coolers on all Sport and RH mowers
Units
Affected: All Sport and RH mowers with a serial number from 24188
through 30058 that have the hydraulic oil cooler. Mowers
beyond this serial number range have been produced to
updated standards according to new design.
Situation: It has been determined that the hydraulic oil cooler for these
mowers is unnecessary for the hydraulic system and that it
should be removed. All mower registrations must be completed
and entered into the Wright online registration system and
communicated to Wright Manufacturing within 20 days of
receipt of this letter. Failure to do this exposes the Dealer to
the liability of consequential damages should a problem
develop with the mower related to the items in this bulletin.
This product recall requires that all affected mowers have
the hydraulic oil cooler removed as quickly as possible
and no later than 40 days from the date of this bulletin. In
cases where the mower has been retailed, the Dealer
should make very effort to accommodate those mowers
into their schedule at the earliest possible date.
We will be contacting all currently registered mower
owners to inform them of the need for this service but
request that each Distributor/Dealer contact their
customers as well. Additionally, we may not have
registration for all retailed mowers which makes it
impossible for us to contact the consumer. In the event
that engine damage occurs due to the consumer not
having knowledge of this recall due to non-registration, the
10

Bulletin # 055

May 10, 2006
liability for consequential damage will be on the selling
Dealer.
This work is to be done in conjunction with Bulletin #056
The Fix: Using the attached instructions:
1) Remove the hydraulic oil cooler from all affected mowers
2) ONLY IF MOWER RETAILED - Remove the engine shroud
and clean the engine cooling area and fins with compressed
air
For units that have been retailed, contact the end-user to have
these services performed. Units that have been retailed but
not registered must be registered immediately.
*** All affected mowers need to have this update performed.
No affected mower should be retailed without this service being
performed
*** The engine manufacturer recommends cleaning the
dust, dirt and debris from cylinder and cylinder head
cooling fins every 100 hours or more often under dusty
conditions. Grass clogged cylinder heads and cooling fins
can contribute to engine overheating and we strongly
recommend this service item be done frequently. Please
take this opportunity to perform this necessary
maintenance service. The plastic engine shroud must be
removed to perform this service.
Claim
Procedure: 0.6 hour of labor allowed. An additional 0.4 is allowed for
cleaning the engine cooling fins if the unit has been retailed.
Complete the attached “Quick-Claim-Form” and submit within
15 days of the date of repair. Work must be performed at the
same time as Bulletin #056 and should be claimed on the same
claim form.

ADDING MUFFLER HEAT SHIELD ON SPORT &
RH MOWERS
*** PRODUCT RECALL ***
Subject: Adding the muffler heat shield on all Sport and RH mowers
NEW PART # 91410026 – includes heat shield and gaskets
Units
Affected: All Sport and RH mowers with a serial number from 24188
through 33155. You may find that some of the serial numbers
in this range have had the update performed prior to your
receiving the mower.
Situation: It has been determined that a muffler heat shield needs to be
added to the affected mowers listed above. This is an
important recall. All mower registrations must be completed
and entered into the Wright online registration system and
communicated to Wright Manufacturing within 20 days of
receipt of this letter. Failure to do this exposes the Dealer to
the liability of consequential damages should a problem
develop with the mower related to the items in this bulletin.
This product recall requires that all affected mowers have
the muffler heat shield installed as quickly as possible, and
no later than 40 days from the date of this bulletin. In

We will be contacting all currently registered mower
owners to inform them of the need for this service but
