Pre-Delivery Service Of Mower By Dealer
If you are not completely familiar with the Safety Instruction
Manual read it now before proceeding with the Pre-Delivery
WARNING
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:
• Remove spark plug wire from spark plug(s).
• Inspect the mower for any damage, unusual conditions or missing parts.
• Inspect 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.
• Check to ensure belt guard is in place before operation.
• Check (and fill if necessary) engine oil level according to the engine manufacturer’s recommendation.
• Check (and fill if necessary) hydraulic fluid level. The level should be about 1-2” below the top of the
oil fill. Use fully SYNTHETIC oil: Mobil-1 15W-50.
• Check 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. Higher pressures will
help keep the caster tires on their rims when impacted from the side but give a stiffer ride. Some
Front Casters are equipped with non-pneumatic tires and do not require any air.
• Remove the blade belt cover and check (and tighten if necessary) all belt tensions according to
specifications discussed later in this manual. DO NOT OVERTIGHTEN.
• Rotate the blade pulleys slightly to see if they all turn together. (Note: Clutch Brake will create some
resistance.)
• Lubricate all moving parts
• Reinstall the blade belt cover.
• Remove 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).
• Fill fuel tank with regular unleaded gasoline. Open fuel valve under gas tank.
• DO 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.
• Set 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.
• With hand controls and speed control in the neutral position, apply the parking brake.
• Open the manual bypass valve on top of each pump a half-of-a-turn counterclockwise.
• Reattach spark plug wires to spark plugs.
• Before 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-aturn counterclockwise.)
• Start 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,
Service of the mower. Only your authorized Wright Mower
dealer should perform the Pre-Delivery Service of the mower

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. 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 if the parking brake locking system (if
applicable) prevents the unit from being driven while engaged. If not, service the parking brake
locking system.
• Before 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.
• 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. 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.
• Disengage the blades, shut off the engine and remove the mower from the stand(s).
• Drive 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.
• As 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.
