CONTROLS Tracking IMPORTANT INFORMATION Always raise the deck to the highest position for transport. Hydro Release Levers If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure for the rear tires is 15 psi (1 bar). 1. Tracking adjustments are made using the tracking bolts. 2. For preliminary tracking adjustment, move unit to an open, unobstructed area such as an empty parking lot or open field. 3. Turn the tracking bolts in as far as possible. 4. Back the tracking bolts out 4 full turns. Any more than four turns could damage the unit. 5. Test operate unit by driving it at full throttle and the full forward position on both motion control levers. Gradually turn in the tracking bolt on the right hand side until the unit noticeably starts drifting right. 6. Drive forward at full throttle with both motion control levers in the full forward position. Gradually turn in the tracking bolt (left side) until unit tracks straight. Cutting Height Pedal The desired cutting height is set with the height pin. The cutting height pedal releases the deck lift to place the deck at the selected height. For transport, push the lift pedal fully forward until the deck lift latches in the transport (highest) position. Transmission bypass levers must be engaged when pushing or pulling the machine. Transmissions are put into bypass mode by rotating the levers to the horizontal position. The bypass levers are located at the front of both transmissions. See Manual Transport in the Operation section. Fuel Tank Read the safety instructions before refueling. The capacity for the tank is five gallons. Regularly check the gas cap gasket for damage and keep the cap correctly tightened. The engine will run on a minimum of 87-octane unleaded gasoline (no oil mix). Environmentally adapted alkylate gasoline can be used. See Technical Data concerning ethanol fuel. Methanol fuel is not allowed. Do not use E85 alcohol based fuel. Damage to the engine and components can occur. When operating in temperatures below 32°F, use fresh, clean winter grade gasoline to ensure good cold weather starting. 15
