Safety Instructions - Before Operating
6. Do not wear loose tting clothing that could get
caught in moving parts. Do not operate this machine while wearing shorts; always wear ade-
quate protective clothing, including long
pants. Wearing safety glasses, safety shoes,
and a helmet is advisable and required by some
local ordinances and insurance regulations.
7. Prolonged exposure to loud noise can cause
impairment or loss of hearing. Operator hear-
ing protection is recommended. Wear a suitable hearing protective device, such as earmuffs or earplugs.
8. Keep all protective shields and safety de-
vices in place. If a protective shield, safety
device, or decal is damaged, unusable, or missing, repair or replace it before operating the
machine.
9. Be sure interlock switches are functioning
correctly, so the engine cannot be started unless the Forward Speed Control lever is in the
NEUTRAL-PARK position, and the PTO clutch
is in the DISENGAGED position. Also, the engine should stop if the operator lifts off the seat
with either the Forward Speed Control (FSC)
out of the NEUTRAL-PARK position or the PTO
clutch in the ENGAGED position.
11. Never attempt to make any adjustments
while the engine is running, except where
spe cically instructed to do so.
12. The electrical system battery contains sulfuric
acid. Avoid any contact with skin, eyes, and
clothing. Keep the battery and acid out of reach
of children.
WARNING
This product can expose you to chemicals
including Di-(2-ethylhexyl) phthalate which
is known to the State of California to cause
cancer, and Di-(2-ethylhexyl) phthalate,
which is known to the State of California
to cause birth defects or other reproductive harm. For more information go to
www.P65Warnings.ca.gov.
NOTE: There is a 1/2 second time delay func-
tion on the seat switch to avoid engine power
interruption when driving over bumps.
10. Handle diesel with care:
a. Use an approved fuel container.
b. Never add fuel to a running engine or hot
engine (allow hot engine to cool several
minutes).
c. Keep matches, cigarettes, cigars, pipes,
open ames, or sparks away from the fuel
tanks and fuel container.
d. Always ll the fuel tank(s) outdoors using
care. Fill to about one inch from the top of
the tank. Use a funnel or spout to prevent
spilling.
e. Replace the machine fuel cap(s) and con-
tainer cap securely and clean up any spilled
fuel before starting the engine.
10
Safety Instructions - Operating
WARNING
● Always keep the ROPS roll bar in the up-
right and locked position when operating.
● Always use the seat belt when the roll bar
is upright.
● Only lower the roll bar when absolutely
necessary for overhead clearance.
● Never use the seat belt when the roll bar
is lowered.
1. Operate the mower only in daylight or in
good articial light with good visibility of the area
being mowed.
2. Sit on the seat when starting the engine and
operating the machine. Keep feet on the deck
footrests at all times when the tractor is moving
and/or mower blades are operating. Never op-
erate the tractor without a deck or implement installed.
3. For a beginning operator, learn to steer (maneuver) the tractor with a slow engine speed
before attempting any mowing oper ation.
Be aware that, with the front mounted mower
conguration, the back of the tractor swings to
the outside during turns.
5. In case the transmission drive belt breaks during operation, and if the machine is on a slope,
the machine will freewheel down the slope. To
maintain control, immediately (1) Release the
steering levers and simultaneously (2) Move
the FSC to the NEUTRAL-PARK position.
When the machine is stopped or moving slowly,
engage the parking brake.
NOTE: The emergency stop procedure is exactly the same procedure used to normally stop
and park the machine.
6. Disengage the blade clutch and put the FSC in
the NEUTRAL-PARK position before starting
the engine (an ignition interlock switch normally
prevents starting of the machine if these controls are in the OPERATING position).
7. Do not operate machine if the operator pres-
ence safety switch system is not working.
Verify proper operation by having the operator
lift off the seat with the engine running and moving two controls, one at a time; (1) Move the
FSC lever out of the NEUTRAL-PARK position,
and (2) Engage the PTO Clutch. Moving either
control should stop the engine after a 1/2 second delay.
8. Do not run the engine in a conned area
without adequate ventilation. Exhaust fumes
are hazardous and can be deadly.
9. Do not carry passengers - maximum seating
capacity is one (1) person.
DANGER
Do not mow around overhanging tree
branches or bushes at the same height as
the operator’s torso and head where inadvertent contact may cause injury.
4. Remember, for an emergency stop, the forward
motion of the tractor can always be stopped by
pulling the Forward Speed Control (FSC) into
the NEUTRAL-PARK position.
10. Watch for holes, rocks, and roots in the terrain
and for other hidden hazards. When mowing
tall grass, mow higher than desired to expose
any hidden obstacles. Then, clean the area and
mow to the desired height.
11. Avoid sudden starts or stops. Before back-
ing the machine up, look to the rear to be sure
no one is behind the machine. Watch carefully
for trafc when crossing or working near roadways.
12. When moving forward, do not suddenly put the
tractor in reverse by rapidly pulling on the steering levers, especially when going downhill, as
this can lift the tractor tail wheel off the ground
and set up a bucking motion due to operator
overcontrol. If bucking does occur, immediately
stop the bucking action by pulling the Forward
Speed Control (FSC) lever into the NEUTRAL-
PARK position.
11
Safety Instructions - Operating
13. Disengage the blade drive when transporting
the machine across drives, sidewalks, etc.
Never raise the mower deck while blades are
rotating.
DANGER
Do not mow or drive the tractor within 5
feet (1.5 meters) of an embankment or retaining wall with drop off.
14. The maximum recommended slope operating angle is 15 degrees or 26% grade. When
operating the machine on a slope, reduce
speed and use caution to start, stop, and maneuver. To prevent tipping or loss of control of
the machine, avoid sharp turns or sudden
changes in direction. Do not operate the ma-
chine on a slope greater than 15 degrees.
15. Never adjust cutting height with the engine
running. Before adjusting cutting height or
servicing, disengage the blade clutch (PTO),
stop the engine, and remove the ignition key.
Wait for all movement to stop before getting off
the seat.
NOTE: The blade/PTO brake should normally
stop drive line rotation within ve (5) seconds of
dis engaging the PTO clutch.
16. For side discharge mower decks, do not oper-
ate with the grass deector shield removed.
Keep the deector in the low est possible position.
17. When using the tilt-up deck, observe the fol-
lowing:
18. In case of a clogged or plugged mower deck:
a. Disengage the blade clutch (PTO), engage
the parking brake, and turn the engine off
before leaving the seat.
b. LOOK to make sure blade drive shaft
move ment has stopped before trying to unclog the system.
c. Never place hands under the deck - use a
stick or similar tool to remove clogged
ma terial.
19. If the cutting blades strike a solid object or the
machine begins to vibrate abnormally,
immediately disengage the blade clutch
(PTO), stop the engine, and wait for all moving parts to stop. Thoroughly inspect the
mower and repair any damage before restarting
the engine and operating the mower. Make
sure cutter blades are in good condition and

Assembly Instructions
SETUP INSTRUCTIONS
Walker Mowers are shipped partially assembled to
our distribution network, and are typically assembled by the selling dealer. For any additional assembly besides the following, contact your Walker
dealer.
Battery Service
Raise the utility bed and mower body up for battery
access. Check the battery for electrolyte level and
charge. The electrolyte level should be at the
bottom 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.

Tire (Ref)
Battery
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 technician can activate the battery safely. DO
NOT attempt to activate the battery unless
you are experienced in battery service
work. The following activation and charging instructions are provided for use by a
trained battery technician.
DANGER
Battery electrolyte is a poisonous and corrosive sulfuric acid solution.
● Avoid spillage and contact with skin,
eyes, and clothing - causes severe burns.
Battery Location
IMPORTANT: Make sure battery is securely
mounted in the frame. A loose battery may cause
damage to the case resulting in acid leakage and
se vere damage to the machine. A hazard may be
cre ated by damage to critical working parts and
safety systems.
IMPORTANT: Never disconnect battery while engine is running.
Wet Battery Service
If the battery has been shipped wet, but the electrolyte 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.
● To prevent accidents, wear safety gog-
gles and rubber gloves when working with
electrolyte.
● Neutralize acid spills with baking soda
and water solution.
To ll (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 lling with electrolyte.
IMPORTANT: Obtain and use only battery
grade sulfuric acid electrolyte with a 1.265 specic gravity to activate the battery. DO NOT use
water or any other liquid during initial activation.
2. Remove the ller caps and carefully ll each cell
until the electrolyte is just above the plates.
3. After the battery is lled with electrolyte, replace
the ller caps and charge the battery. Refer to
Battery Charging.

Assembly Instructions
Battery Charging
DANGER
BATTERIES PRODUCE EXPLOSIVE GASES
● Charge the battery in a well-ventilated
area, so that gases produced while charging can dissipate.
WARNING
Make sure the battery cap vents are open.
Improper venting of the battery COULD
cause a battery explosion.
● Keep sparks, ames, and smoking mate
rials away from the battery at all times.
● Make sure the battery cap vents are open
after the battery is lled with acid (check
manifold vent on each cap).
● Make sure the battery charger is un-
plugged before connecting or disconnecting cables to the battery.
1. Charge the battery at 15 amps for 10 minutes.
DO NOT exceed 20 amps maximum recom-
mended charging rate. Charge until specic
gravity is at least 1.250. Total charging time
should not exceed one (1) hour.
2. After charging the battery, adjust the electrolyte
level to the bottom of the vent wells [1/4 to 1/2 in.
(6 to 13 mm) above the plates].
IMPORTANT: DO NOT overll the battery.
Electrolyte will overow through the vented
caps onto parts of the machine and WILL result
in severe corrosion.
