Operation The Safety Interlock System Understanding the Safety Interlock System The safety interlock system is designed to prevent the engine from starting unless: • The power take off (PTO) is “OFF” • The gear shift lever is in “N” neutral. The safety system is designed to stop the engine if: • You rise from the seat when the clutch/brake pedal is released. • You rise from the seat when the blade (PTO) is “ENGAGED.
Operation POTENTIAL HAZARD • A child or bystander could be backed over by a riding mower with its blade(s) engaged. 1 WHAT CAN HAPPEN • Blade contact will cause serious personal injury or death. HOW TO AVOID THE HAZARD • Do not mow in reverse unless absolutely necessary. • Always look backward and down before backing up. • Use “Key Choice” switch only if you are certain no children or other bystanders will appear in the mowing area.
Operation 4. Sit on the seat, move gear shift into neutral, deck engagement lever into DISENGAGE and ensure parking brake is engaged. Rotate ignition key to START. Engine should start and continue to run. Then engage deck engagement lever and carefully raise off the seat: the engine should stop. If engine does not stop running, shut engine off and have interlock system repaired by an Authorized TORO Service Dealer.
Operation Side Discharging or Bagging To side discharge or use bagging attachment, stop engine and wait for all moving parts to stop. 1. 2. 3. Remove the wing nut securing the discharge cover (Fig. 8) to the mower housing. NEVER REMOVE THE GRASS DEFLECTOR FROM THE MOWER HOUSING (Fig. 8). Lift the grass deflector and metal tab together to enable the removal of the metal tab. Continue to lift the grass deflector enough to remove the plastic discharge cover off the long bolt.
Operation Note: For reverse motion, with the PTO engaged, the operating–in–reverse feature must be deactivated by the “key choice” switch located on the right hand side panel just below and to the rear of the seat. Stopping the Machine Positioning the Seat The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable. 1. Raise the seat and loosen the lock nuts (Fig. 9). 2.
Operation Recyclerr Rider Tips Tips for Cutting Grass Recyclerr Rider Features Your Toro Recyclerr rider has a new and completely different cutting concept. It leaves your lawn with a bagged look without bagging clippings. The rider is equipped with special parts (Fig. 10) which increase your rider’s ability to cut and recut grass clippings, leaves, and other yard debris into tiny particles which are injected down into the grass.
Operation POTENTIAL HAZARD • Unexpected blade contact can occur WHAT CAN HAPPEN • Personal injury can occur from contact with blade HOW TO AVOID THE HAZARD • Depress clutch and brake pedals, shift into neutral and turn ignition key to “OFF” position. Remove wire from spark plug to prevent someone from accidentally starting the machine. • Never attempt to clear a clog with the engine running and the blade engaged.
Operation • Alternate mowing direction. This helps disperse clippings over lawn for even fertilization. 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 blades(s) and thrown debris will cause injury or death. • Overlap cutting swaths instead of cutting a full swath with each pass.
