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 pro-
tective footwear.
9
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; 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 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
specically 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 Phenylethane which is known to the State of California to cause cancer, and N-Methyl-2-Pyrrolidone, 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 gasoline with care. Gasoline is highly
ammable 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 ames, or sparks away from the fuel
tank and fuel container.
d. Always ll the fuel tank 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 and container
cap securely and clean up any spilled fuel before starting the engine.
10
Safety Instructions - Operating
1. Operate the mower only in daylight or in
good articial 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 conguration, 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 either of the transmission drive belts break 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 posi- tion. 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 conned 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 back- ing the machine up, look to the rear to be sure no one is behind the machine. Watch carefully for trafc 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.
13. Disengage the blade drive when transporting the machine across drives, sidewalks, etc. Nev-
er 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 ve (5) seconds of
disengaging the PTO clutch.
16. For side discharge mower decks, do not oper- ate with the grass deector shield removed. Keep the deector in the lowest possible posi­tion.
17. When using the tilt-up deck, observe the fol-
lowing:
a. Do not move tractor with deck in tilt-up
position.
20. In case of a clogged or plugged mower deck
or GHS catching system:
a. Disengage the blade clutch (PTO), engage
the parking brake, and turn the engine off before leaving the seat.

Battery Service
CAUTION
Important Battery Service, Installation, and Charging Tips for Electronic Fuel Injection Engines:
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 specic 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 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.
Dry Battery Service
● Do not allow the battery cables to touch opposing terminals. When connecting bat­tery 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 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 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 per­forming any welding on equipment.
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.
18
Assembly Instructions
DANGER
Battery electrolyte is a poisonous and cor­rosive 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.
Battery Charging
DANGER
BATTERIES PRODUCE EXPLOSIVE GASES
● Charge the battery in a well-ventilated area, so that gases produced while charg­ing can dissipate.
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).
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 spe­cic 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.
● Make sure the battery charger is un- plugged before connecting or disconnect­ing cables to the battery.
IMPORTANT: Always disconnect the negative (-)
battery terminal before charging. Failure to do so can result in damage to the ECU.
1. Charge the battery at 15 amps for 10 minutes.
DO NOT exceed 20 amps maximum recom-
mended charging rate. Charge until specic
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 overll the battery. Electrolyte will overow through the vented
caps onto parts of the machine and WILL result in severe corrosion.
3. Install battery.

Assembly Instructions
Deck Leveling
The mower deck and support frame are jig welded; within normal tolerances, very little, if any, shimming should be required to level the deck. Tire pressure
will inuence the levelness of the deck. Check the
tire pressure of all pneumatic tires as a possible cause of the deck not being level.
1. Position mower on a smooth, level surface. Set the cutting height to the highest position - 4 in. (102 mm) - for easy access under the deck to measure blade height. Refer to ADJUSTING CUTTING HEIGHT in Operating Instructions.
WARNING
The machine must be shut off during this procedure.
2. Check the side-to-side level. Rotate each blade sideways and measure the distance
from blade tip to ground on each side. If mea­surements vary more than 1/8 in. (3 mm), add a washer shim under the deck support pins on the low side to level the deck.
NOTE: A block of wood cut 4 in. (102 mm) high is a convenient gauge to measure blade height above ground during the leveling process.
4 in. (102 mm)
Wood Block
Should not vary more
than 1/8 in. (3 mm)
side-to-side
3. Check the front-to-rear level. Rotate the blades to point forward. Measure the distance from blade tip to ground on the front and rear. The rear of the blade should be 1/8 to 1/4 in. (3 to 6 mm) higher than the front of the blade; shim the rear (or front) deck support pins equally to achieve at least 1/8 in. (3 mm) difference.
Should be 1/8 in. (3 mm)
to 1/4 in. (6 mm) higher
at the rear of the blade
NOTE: For decks with three (3) staggered blades, the front-to-rear level should be set using the middle blade pointing forward, and either out­side blade pointing back.
