Assembly Instructions

SETUP INSTRUCTIONS

Walker Mowers are shipped partially assembled.
After uncrating the tractor and mower deck, initial
setup is required.
NOTE: During the process of unpacking, any dam-
aged or missing parts should be noted and reported
to the delivering carrier immediately (put in writing
within 15 days). The carrier will provide directions
for proceeding with a claim to receive compensation
for damage.

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 ft-lb
(101.7 to 115.2 N·m). Drive tires are 18 x 8.50-10,
4-ply; rear tire is 13 x 6.50-6, 4-ply.
•
Check and adjust the inflation of the tires. The
tire inflation recommendations are:
Drive = 15 PSI (103 kPa)
Rear = 20 PSI (137 kPa)

Battery Service

Tilt mower body up (lift on rear of body) for battery
access. 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 specific 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 mount-
ed 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 sys-
tems.

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.

Dry Battery Service

DANGER
Activating a battery can be dangerous.
The battery should be taken to a reliable
service station, battery store, or power
equipment dealer where a trained techni-
cian can activate the battery safely. DO
NOT attempt to activate the battery unless
you are experienced in battery service
work. The following activation and charg-
ing instructions are provided for use by a
trained battery technician.
DANGER
Battery electrolyte is a poisonous and cor-
rosive sulfuric acid solution.
•
Avoid spillage and contact with skin,
eyes, and clothing - causes severe burns.
•
To prevent accidents, wear safety gog-
gles and rubber gloves when working with
electrolyte.
•
Neutralize acid spills with baking soda
and water solution.
To fill (activate) battery with electrolyte (if battery has
been shipped dry):
1. Remove the battery hold-down bar, disconnect
the battery cables and lift the battery out of the
tray.
IMPORTANT: Battery must be removed from
the mower before filling with electrolyte.
IMPORTANT: Obtain and use only battery
grade sulfuric acid electrolyte with a 1.265 spe-
cific gravity to activate the battery. DO NOT use
water or any other liquid during initial activation.
2. Remove the filler caps and carefully fill each cell
until the electrolyte is just above the plates.
