SETUP INSTRUCTIONS
Walker Mowers are shipped partially assembled to
our distribution network, and are typically assem-
bled by the selling dealer. For any additional as-
sembly besides the following, contact your Walker
dealer.
Tire Installation (Tractor)
● Install the drive tires using the eight (8) lug bolts
that are supplied with the Owner’s Packet of mate-
rials. Bolts are torqued to 75 to 85 lb·ft (102 to 115
N·m). Drive tires are 18 x 9.50-8, 4-ply; rear tires
are 13 x 5.00-6, 4-ply.
● Check and adjust the ination of the tires. The
tire ination recommendations are:
Drive = 15 PSI (103 kPa)
Tailwheel = 20 PSI (137 kPa)
Battery Service
CAUTION
Important Battery Service, Installation, and
Charging Tips for Electronic Fuel Injection
Engines:
● Do not allow the battery cables to touch
opposing terminals. When connecting bat-
tery cables attach the positive (+) cable to
positive (+) battery terminal rst, followed
by negative (-) cable to negative (-) battery
terminal.
● Never start the engine when the cables
are loose or poorly connected to the bat-
tery terminals.
● Never disconnect battery while engine
is running.
● Never use a quick battery charger to
start the engine.
● Never “jump start” the engine using an-
other source. Electricity uctuations can
damage the ECU (Electronic Control Unit).
● Always disconnect negative (-) battery
cable lead before charging battery, and
also unplug harness from ECU before per-
forming any welding on equipment.
Raise front mower body up for battery access (refer
to Front Body Latch Release in Operating Instruc-
tions). Check the battery for electrolyte level and
charge. The electrolyte level should be at the bot-
tom of the vent wells [1/4 to 1/2 in. (6 to 13 mm)
above plates]. If the specic gravity is less than
1.225, the battery needs charging. If the battery has
been shipped dry, or is wet but needs service, refer
to the following instructions.
IMPORTANT: Make sure battery is securely
mounted in the frame. A loose battery may cause
damage to the case resulting in acid leakage and
severe damage to the machine. A hazard may be
created by damage to critical working parts and
safety systems.
Wet Battery Service
If the battery has been shipped wet, but the electro-
lyte level is low or the battery needs to be charged
then:
1. Fill each battery cell with distilled water to the
bottom of the vent wells.
2. Charge battery. Refer to Battery Charging in
this section.
