Operation The Safety System Understanding the Safety System The safety system is designed to prevent the engine from starting unless: • The clutch/brake pedal is depressed • The blade control (PTO) is “DISENGAGED” The safety system is designed to stop the engine if you rise from the seat when the clutch/brake pedal is released or the blade is “ENGAGED.” Operating–in–Reverse An interlock feature is provided that prevents the Power Take Off (PTO) from operating while the tractor is traveling in reverse.
Operation 1 2. With the ground speed selector in neutral “N,” move the blade control (PTO) to “DISENGAGED” and release the parking brake. Now turn the ignition key to “START”; the engine should not crank. 3. With the ground speed selector in neutral “N,” set the parking brake and move the blade control (PTO) to “DISENGAGED.” Now start the engine. While the engine is running, release the parking brake and rise slightly from the seat; the engine should stop. 4.
Operation Driving Forward or Backward The throttle control regulates the engine speed as measured in rpm (revolutions per minute). To go forward or backward, depress the clutch/brake pedal. Move the ground speed selector to the desired forward speed or reverse. As you slowly release the pedal, the machine will begin to move. Steer the machine with the steering wheel.
Operation Side Discharge or Mulch Grass Installing the Discharge Cover To convert from side discharge to a mulching mower, install the discharge cover into the opening at the side of the mower. POTENTIAL HAZARD • Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. WHAT CAN HAPPEN • Contact with rotating mower blade(s) and thrown debris will cause injury or death. 1.
Operation Tips for Mowing Grass Fast Throttle Setting For best mowing and maximum air circulation, operate the engine at “FAST.” Air is required to thoroughly cut grass clippings, so do not set the height-of-cut too low or totally surround the mower by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.
