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.
Assembly Instructions PREOPERATING CHECKLIST Before operating the mower for the first time, and as a routine before daily operations, it is important to make sure the mower is properly prepared and ready for operation. The following is a list of items to be checked. (For a mower with frequent operation, some of these items will not need to be checked every day, but the operator should be aware of the condition of each.) For proper fuel and lubricants refer to Specifications.
Assembly Instructions INSPECT THREE (3) DRIVE BELTS CAUTION Engine, PTO, and Hydrostatic Ground Drive. CHECK HYDROSTATIC TRANSMISSION OIL LEVEL Refer to LUBRICATION for Checking Hydrostatic Transmission Fluid Level in Maintenance Instructions.
Operating Instructions CONTROL IDENTIFICATION, LOCATION, AND FUNCTION CAUTION Before operating the mower, become familiar with the location and function of all operator controls. Knowing the location, function, and operation of these controls is important for safe and efficient operation of the mower. Ignition Switch The ignition switch is located on the right front of the body and is used to start and stop the engine.
Operating Instructions Engine Throttle Steering Levers The throttle control lever (red knob) is located on the left side of the seat and is used to control engine speed. Moving the lever forward toward the FAST position increases engine speed; moving it backward toward the IDLE position decreases engine speed. Each drive wheel is controlled by its own independent steering lever, for both steering function and FORWARD/REVERSE motion.
Operating Instructions Transmission Lockout Levers The transmission lockout levers disengage the hydrostatic transmissons. By lifting the lever on top of the transmission and locking it into place with the lockout cam, the hydrostatic transmissions are released to permit freewheeling. By releasing the cam and lowering the lever, the transmissions are engaged for normal operation. The transmission lever in the LOCKOUT position is used to enable moving the machine without the engine running (e.g.

Operating Instructions STARTING THE ENGINE IMPORTANT: DO NOT crank the engine continuously for more than 10 seconds at a time. If the engine does not start, turn the key to the OFF position and allow a 60 second cool-down period between starting attempts. Failure to follow these guidelines can damage the starter motor and shorten battery life. CAUTION Before operating the mower, read and understand all Safety Instructions and Operating Instructions. 3.
Operating Instructions WARNING Beginning Recommendations are: ♦ Learn operation of the mower in an open area away from buildings, fences, and obstructions. Learn operation on flat ground BEFORE operating on slopes. 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 position.
Operating Instructions NOTE: Smooth action on the steering levers will produce smooth mower operation. Remember to keep the engine and ground speed slow until learning the control response. 4. 5. The FSC may be adjusted forward for faster ground speed and backward for slower ground speed. When mowing, ground speed should be adjusted to match the load on the cutter blades, i.e., as the engine pulls down in heavy cutting, pull back on the FSC lever to reduce ground speed.
Operating Instructions STOPPING THE MACHINE 1. Slow the engine to idle; put the throttle in the IDLE position. 2. Pull the steering levers to the NEUTRAL-PARK position and then move the FSC lever backward to the NEUTRAL-PARK position. 3. Disengage the blade clutch. IMPORTANT: DO NOT disengage the blade clutch with high engine speed (above 1/2 throttle) since the brake action on the blade drive will cause premature wear of the PTO Drive Belt.
Operating Instructions TRANSMISSION LOCKOUT Lockout Lever IMPORTANT: DO NOT TOW this mower with the transmission lockout engaged. Towing can produce excessive internal pressure and damage the transmission. To move the mower with the engine NOT running (dead battery, maintenance, etc.), the hydrostatic transmissions are unlocked (released). Plunger Released 1. Raise the body. 2. Lift the transmission lockout lever on both the RH and LH transmissions and secure into place with the locking cam. 3.
Operating Instructions • Make sure the mower is leveled properly for a smooth cut. Refer to Deck Leveling in Assembly Instructions. • Use an alternating stripe mowing pattern for best appearance and vary the direction of the stripe each time the grass is mowed to avoid wear patterns in the grass. Maximum Recommended Side Slope - Do Not Operate on Steep Slopes • Avoid damage to the grass by slipping and skidding of the drive tires.

Operating Instructions General Information The Grass Handling System (GHS) consists of a rear discharge mower deck connected to a 9 in. (23 cm) blower and a rear mounted grass catcher with 6.7 bushel (238 liters) capacity. The GHS blower operates any time the mower blade clutch is engaged and moves grass through the rear discharge deck chute into the grass catcher. Blower airflow is exhausted out the back of the grass catcher, through a filtering screen.
Operating Instructions Clogging Checklist • Check the amount of flat section remaining at In case of clogging, there will be a distinct change in the sound of the blower, i.e., the blower sound will stop. Also, the mower deck will begin to leave a trail of grass clippings. When this occurs, stop the engine, disconnect the spark plug wire, and make sure all movement has stopped before attempting to unclog. blade tip. This is the area that is ground away (removed) when the blades are sharpened.
Operating Instructions • Check that the openings in the air exhaust screen in the grass catcher are not plugged. If the screen is clogged, refer to Cleaning the GHS Exhaust Screen in this section. Remember, anything that restricts airflow or material flow along the entire path from the mower deck to the grass catcher can cause clogging. Using the Tilt-Up Deck Refer to CLEANING of Grass Buildup in Mower Housing in Maintenance Instructions.
Operating Instructions Dumping the Catcher Using the Dump Bag For dumping, the catcher either tailgate dumps into a disposal area or dumps into the optional dump bag. The dump bag is a reusable nylon fabric bag designed to conveniently move grass clippings from the catcher to a remote disposal area or container. 1. Tailgate Dumping 1. 2. Tilt the catcher back to dump by lifting on the handle on the front of the catcher. 3. Lower the catcher smoothly down to the normal operating position.
Operating Instructions Tailgate Door Handle Catcher Dump Handle Hook Bag on Bumper Positioning Dump Bag on Catcher 6. Close the door by holding the door handle with the left hand and releasing the safety latch on the door hinge mechanism with the right hand.

The gearboxes are permanently lubricated (oil filled) and sealed requiring no scheduled lubrication.
Maintenance Instructions Gear Axle Lubrication • The gear axle oil lubrication is SAE 80W-90 (API GL-5) gear lube. • Check the axle oil level after every 100 hours of operation by removing the oil level plug. If additional oil is needed, remove the breather vent on top of axle and fill until oil is at the level plug. • Change axle oil every 1000 hours or two (2) years.
Maintenance Instructions CLEANING CLEANING Push Button to Reset Indicator After Service Engine Air Cleaner System Donaldson Radialseal™ Air Cleaner A remote mounted Donaldson Radialseal™ air cleaner provides the air filtering function. The paper filter element slides over an outlet tube inside the air cleaner canister with radial sealing action, eliminating the possibility of dust leaks due to improper filter installation.
Maintenance Instructions 4. Use a bright light inside the element to inspect for damage. Check the element very carefully for pin holes or other damage that will allow dirt to leak through the paper media. Replace element if necessary. 5. Check the condition and resilience of the radial sealing surface (inside of the open end) of the filter. Replace the filter if any cracks, tears, or other damage to the sealing surface are noted. 6. 8. 9.
Maintenance Instructions IMPORTANT: Service the fuel filter screen only in a clean area where the fuel filter components will not be contaminated by any dust and dirt. CLEANING Rotating Engine Air Intake Screen DANGER Gasoline is extremely flammable and can be highly explosive. To minimize danger: • Use an approved fuel container for gasoline. • DO NOT allow open flames or sparks while performing maintenance or refueling; DO NOT smoke while working with fuel.
Maintenance Instructions 1. 2. 3. Inspect accessible cooling fins and clean with compressed air as needed. If the buildup is excessive, refer to step 2. Remove the spark plug wire and disconnect the breather tube on the valve cover. Do not disconnect the breather tube from the carburetor side. Remove the cylinder head shroud by removing the five (5) bolts, as shown in the Inspect and Clean Cylinder Head Cooling Fins photo.
Maintenance Instructions CAUTION CLEANING 2. Do not operate machine with deck tilt-up pivot joint unlocked. GHS Blower Normally, the GHS blower operates with no maintenance or cleaning. However, when mowing grass that is dirty and damp (especially springtime mowing), a deposit of dirt may accumulate inside the blower housing, causing wear and binding of the blower wheel. When operating in these conditions, inspect the blower frequently for dirt buildup.
CLEANING/ CHECKING/SERVICING Maintenance Instructions Hydrostatic Transmission Cooling Fins CHECKING/SERVICING DANGER Keeping the cooling fins on the hydrostatic transmissions clean and free of obstruction is essential to avoid overheating the transmission fluid and shortening transmission life. The cooling fins should be checked every 100 hours; and cleaned if necessary. To clean the fins, use compressed air and/or a pressure washer.
CHECKING/SERVICING Maintenance Instructions 3. Replace filler caps. IMPORTANT: DO NOT overfill the battery. Electrolyte will overflow through the vent tube onto parts of the machine and WILL result in severe corrosion. Cleaning the Terminals If battery terminals are corroded, remove battery from the mower. Using a wire brush, remove corrosion with a solution of one part baking soda and four parts water. Rinse with clean water.
Maintenance Instructions CHECKING/SERVICING WARNING Intersection Wear Area DO NOT try to straighten a blade that is bent. NEVER weld a broken or cracked blade.
