Walker Manufacturing recommends that any service requiring special training or tools be performed by an authorized Walker Mower dealer. There are several general practices to be aware of in the area of safety. Most accidents associated with the operation or maintenance of a Walker Mower are caused by disregarding basic safety precautions or specific warnings. Such accidents, in most cases, can be prevented by being aware of the dangers present.
Information of special importance has been highlighted in bold type in this manual. Refer to Safety Instructions for the meanings of DANGER, WARNING, CAUTION, IMPORTANT, and NOTE.
There are many terms that are either unique to this equipment or that are used as acronyms. The following terms and their definitions will help while using this manual:
•DECK is the mowing attachment mounted on the front of the tractor which includes the carrier frame, deck housing, belt or gear drive components, and cutter blades.
•ELECTRONIC CONTROL UNIT (ECU) controls engine functions such as spark timing, fuel/air ratio, etc.
•FORWARD SPEED CONTROL (FSC) controls the maximum forward speed of the tractor; functioning as a cruise control.
•GRASS HANDLING SYSTEM (GHS®) collects mowed material and deposits it in the catcher.
•GRASS-PAK® SWITCH is mounted on the grass delivery spout (in the catcher) and activates the “full” signal horn when the grass catcher is full.
•GROUND DRIVE refers to the dual hydrostatic transmissions which drive the main wheels.
•HYDROSTATIC TRANSMISSION transmits and controls power from the ground drive belt to the main drive wheel.
•LEFT HAND (LH) refers to the left-hand side of the tractor when the operator is seated facing forward in the tractor seat.
•POWER TAKE-OFF (PTO) transmits engine power to run the cutter blades and GHS blower.
•POWERFIL® spreads the mowed material throughout the interior of the grass catcher by an oscillating delivery spout.
•RIGHT HAND (RH) refers to the right-hand side of the tractor when the operator is seated facing forward in the tractor seat.
•SIDE DISCHARGE (SD) discharges mowed material from the right side of the mower deck.
•STEERING LEVERS steer the tractor by controlling the dual hydrostatic transmissions.
•TRACTOR is the prime mover, including the engine, drive train, operator seat, and controls to operate the mower.
•TRANSMISSION LOCKOUT releases the hydrostatic transmissions to permit freewheeling the tractor.
The tractor serial number plate is affixed to the tractor body just below the left rear corner of the seat.
The mower deck serial number plate is affixed alongside the angle iron framing on the LH side of the LH mower blade drive. Model and serial numbers are helpful when obtaining replacement parts and maintenance assistance. For ready reference, please record these numbers in the space provided.

Safety Instructions - Before Operating
Pay particular attention to any information labeled
DANGER, WARNING, CAUTION, IMPORTANT, and NOTE in this manual.
When you see the Safety Alert Symbol ( ), read, understand, and follow the instructions. Failure to comply with safety instructions may result in personal injury.
The seriousness or degree of importance of each type of information is defined as follows:
DANGER
An IMMEDIATE hazard that WILL result in severe personal injury or DEATH, if warning is ignored and proper safety precautions are not taken.
WARNING
A POTENTIAL hazard that COULD result in severe personal injury or DEATH, if warning is ignored and proper safety precautions are not taken.
CAUTION
Possible hazards or unsafe practices that MAY result in MODERATE personal injury or property damage, or machine damage, if warning is ignored and proper safety precautions are not taken.
IMPORTANT: Identifies mechanical information demanding special attention, since it deals with the possibility of damaging a part or parts of the machine.
NOTE: Identifies information worthy of special attention.
Walker Manufacturing cannot predict every potentially dangerous situation. Therefore, items labeled as such in this manual do not cover all conceivable situations. Any person using procedures, tools, or control techniques not recommended by Walker Manufacturing must take full responsibility for safety.
The Walker Rider Lawnmower has been designed with many safety features to protect the operator from personal harm or injury. However, it is necessary for the operator to use safe operating procedures at all times. Failure to follow safety instructions contained in this manual may result in personal injury or damage to equipment or property.
If you have any questions concerning setup, operation, maintenance, or safety, please contact your authorized Walker Mower dealer or call Walker Manufacturing Company at (970) 221-5614.
1.Read and understand the contents of this Operator’s Manual before starting and operating the machine. Become thoroughly familiar with all machine controls and how to stop the machine and disengage the controls quickly. Replacement Operator’s Manuals are available by sending the Model and Serial Number to:
Walker Manufacturing Company
5925 East Harmony Road
Fort Collins, CO 80528
2.Never allow children to operate rider mower.
Do not allow adults to operate without proper instruction.
3.Clear the area to be mowed of any foreign objects which may be picked up and thrown by cutter blades. Pick up all sticks, stones, wire, and any other debris.
4.Keep everyone, especially children and pets, a safe distance away from the area being mowed.
Do not mow with bystanders in the area.
5.Do not operate the machine barefoot or wearing sandals, sneakers, tennis shoes, or similar lightweight footwear. Wear substantial protective footwear.

Safety Instructions - Before Operating
6.Do not wear loose fitting clothing that could get caught in moving parts. Do not operate this machine while wearing shorts; always wear adequate 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 hearing protection is recommended; particularly for continuous operation of the GHS Model due to blower noise level. Wear a suitable hearing protective device, such as earmuffs or earplugs.
8.Keep all protective shields and safety devices 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.
NOTE: There is a 1/2 second time delay function on the seat switch to avoid engine power interruption when driving over bumps.
10.Handle gasoline with care. Gasoline is highly flammable and its vapors are explosive:
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 flames, or sparks away from the fuel tank and fuel container.
d.Alwaysfillthefueltankoutdoorsusing 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 and container cap securely and clean up any spilled fuel before starting the engine.
11.Never attempt to make any adjustments while the engine is running, except where specifically 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
The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.

Safety Instructions - Operating
1.Operate the mower only in daylight or in good artificial 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 operate the tractor without a deck or imple ment installed.
3.For a beginning operator, learn to steer (maneuver) the tractor with a slow engine speed before attempting any mowing operation.
Be aware that, with the front mounted mower configuration, the back of the tractor swings to the outside during turns.
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.
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 as used to normally stop and park this machine.
7.Do not operate machine if the operator presence 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 confined area without adequate ventilation. Exhaust fumes are hazardous and can be deadly.
9.Do not carry passengers - maximum seating capacity is one (1) person.
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 backing the machine up, look to the rear to be sure no one is behind the machine. Watch carefully for traffic 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 NEUTRALPARK position.
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 dump grass within 5 feet (1.5 meters) of an embankment or retaining wall with drop off.
11
Safety Instructions - Operating
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 machine 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: A blade/blower brake should normally stop drive line rotation within five (5) seconds of disengaging the PTO clutch.
16.For side discharge mower decks, do not operate with the grass deflector shield removed.
Keep the deflector in the lowest possible position.
17.When using the tilt-up deck, observe the following recommendations:
a.Do not move tractor with deck in tilt-up position.
b.Never tilt body forward with deck in tilt-up position.
18.For GHS equipped models, do not operate the machine with the grass catcher in the DUMP position or with the back door OPEN. Dangerous projectiles may be thrown out of the discharge chute or the back of the grass catcher.
19.For GHS equipped models, use care when closing the grass catcher door. Keep fingers and hands away from the hinge and pinch points when the door is being closed. Also, keep fingers and hands clear of the door frame.
The door may slam shut with considerable force.
20.In case of a clogged or plugged mower deck or GHS catching system:
a.Disengage the blade clutch (PTO) and turn the engine off before leaving the seat.
b.LOOK to make sure blade drive shaft and blower drive pulley movement has stopped before trying to unclog the system.
c.Disconnect the spark plug wires.
d.Never place hands under the deck or in the GHS blower - use a stick or similar tool to remove clogged material.
21.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. To prevent accidental starting, disconnect the spark plug wires. 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 blade nuts are torqued to 60 lb·ft (81 N·m) for
gear driven decks, and blade bolts torqued to 70 lb·ft (90 N·m) for belt driven decks.
22.Do not touch the engine or muffler while the engine is running or immediately after stop ping the engine. These areas may be hot enough to cause serious burns.
23.When leaving the machine unattended, disen gage the blade clutch (PTO), stop the engine, and remove the key.
CAUTION
Use leg muscles and firm footing when lifting the catcher to dump; avoid bending at the waist and using back muscles in order to prevent back injury.

CAUTION
Important Battery Service, Installation, and
Changing Tips:
•Do not allow the battery cables to touch opposing terminals. When connecting battery cables attach the positive (+) cable to positive (+) battery terminal first, followed by negative (-) cable to negative (-) battery terminal.
•Never start the engine when the cables are loose or poorly connected to the battery terminals.
•Never disconnect battery while engine is running.
•Never use a quick battery charger to start the engine.
•Never “jump start” the engine using another source. Electricity fluctuations can damage the ECU (Electronic Control Unit).
•Always disconnect negative (-) battery cable lead before charging battery, and also unplug harness from ECU before performing 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 bottom 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 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.
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.
