Page 17: How To Use Your Mower
HOW TO USE YOUR MOWER TO SET PARKING BRAKE (See Fig. 3) Your mower is equipped with an operator presence system. When the engine is running, any attempt by the operator to leave the seat without first setting the park brake will shut off the engine. - Page 18 TO USE THROTTLE CONTROL (See Fig. 3) Always operate engine at full throttle. The Throttle control is equipped with a choke detent. Pressing the throttle control all of the way forward will choke the engine. For full throttle, press throttle control forward until you feel resistance.
- Page 19 NOTE: To begin motion the operator must be in the seat and the parking brake disengaged before the motion control levers can be moved from the neutral slots or the engine will kill. Fig. 4 and 4A. By moving the levers an equal amount forward or back the machine will move in a straight line in that direction.
- Page 20 TO ADJUST THE DECK CUTTING HEIGHT (See Fig. 5) The deck cutting height is obtained by pressing the foot pedal forward to lift the deck. To lower the deck, you apply pressure to the top side of the foot pedal and allow it to pivot while allowing the lift arm to rotate to the rear of the unit.
- Page 21 TO ADJUST ANTI-SCALP ROLLERS (See Figure 6) Anti-scalp rollers are properly adjusted when they are just slightly off of the ground when the deck is at the desired cutting height in the operating position. Anti-scalp rollers then keep the deck in the proper position to help prevent scalping in most terrain conditions.
