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
materials. 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)
Rear = 20 PSI (137 kPa)
Battery Service
CAUTION
Important Battery Service, Installation, and
Changing Tips:
• 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.
