OPERATING THE MOWER It is recommended that before you operate the mower, you allow adequate time to fully understand the controls and operation of the equipment.

Operating Controls Before continuing to read the manual, it is recommended that you take adequate time to identify the controls of the mower.
Starting The Engine: ! DANGER: DO NOT OPERATE THE ENGINE IN A CONFINED SPACE WHERE DANGEROUS CARBON MONOXIDE FUMES CAN COLLECT. CARBON DIOXIDE IS ODORLESS, TASTELESS, AND CAN BE FATAL. After going through the steps as discussed on pages 6-9, you are now ready to start the engine. NOTE: THIS UNIT WAS SHIPPED WITHOUT GAS, BE SURE TO ADD FRESH GAS AND TO DOUBLE CHECK THE OIL IN THE ENGINE BEFORE ATTEMPTING TO START THE MOWER. Figure 2 1.
Turning The Mower To turn the mower in the direction you want to go, gently squeeze the side’s traction control lever (i.e. to go right, squeeze the right traction control lever; to go left, squeeze the left traction control lever). The more a particular traction control lever is squeezed, the sharper a turn the mower will make. Stopping The Mower To stop the mower, gently and evenly squeeze up on both of the traction control levers until the mower comes to a complete stop.
Moving the Mower Without Turning on the Engine 1. 2. 3. 4. Push the parking lever to the “ON” position. Move the neutral lever to the position (figure 8) Push the parking lever to the “OFF” position. You can now move the mower. Before starting to move the mower, make sure the hydro transmission is completely closed. Figure 8 Parking the Mower Push the parking lever to the “ON” position. (figure 9) Do not transport the mower with the parking brake engaged.
Changing The Height Of Cut: DANGER: BEFORE MAKING ANY ADJUSTMENTS AND/OR SERVICING YOUR MOWER, MAKE SURE THE MOWER IS ON LEVEL GROUND, BLADES DISENGAGED, KEYS REMOVED, AND THE ENGINE OFF WITH THE SPARK PLUG WIRE(S) REMOVED FROM THE SPARK PLUGS(S) AND HIDDEN TO PREVENT ACCIDENTAL CONTACT. When your hydro mower is shipped from the factory, the mowing height is set at 2-1/2”. The mowing height may be raised or lowered using a combination of front wheel spacers and blade bolt assembly spacers.
Adjusting the Deck: (refer to Figure 13) Changes to the cutting height can be achieved by repositioning the cutter deck. There are six available positions. This adjustment will also effect the pitch of the deck. NOTE: Pitch is the angle of the blades (comparing front to rear). A 1/4” downward pitch (front of deck down) recommended for best cutting performance.
GENERAL MAINTENANCE Proper maintenance and adjustment of your hydro mower is necessary to keep the mower in good and safe condition. The maintenance of the mower is the responsibility of the owner/operator and must be performed at regular intervals. When replacing any parts or servicing your mower, be sure to use only genuine manufacturer’s replacement parts to assure quality and performance of your mower.

MANUALLY PUSH THE MOWER AWAY FROM THE SPILL AND IMMEDIATELY WIPE UP. Refer to the Engine Owner’s Manual for the type of fuel to use. A fuel shut off valve is located on the bottom of the fuel tank.
Lubrication Points To assure proper lubrication on moving parts, it is recommended that you lubricate the following components with a high-quality EP2 high temperature based grease or equivalent. Should the conditions of operation be more severe than normal, the lubrication interval may be shorter than recommended. GTR/OPE Grease is the recommended lubricant.
