6.Fuses: There is one fuse located in the wiring between the ignition and start switch and other electrical components. This is a stan- dard plug-in type automotive fuse rated at 7.5 amp.

7.Safety Switches: There are five safety switches in the electrical circuit which control the engine. They are (1) the blade clutch switch, (2) the parking brake switch, (3) the left and (4) the right steering lever switches and (5) the seat switch.They operate so that in order to start the engine, the blade clutch switch must be off, the parking brake must be engaged, and both steering levers must be opened-out to the side in the neutral position. Once the engine is started, the seat must be occupied and the parking brake must be released before either of the steering levers is folded up to the operating position or the engine’s electronic ignition will be shorted out and the engine will stop. Also, the seat must be occupied before the blade clutch switch can cause the blades to rotate.

8.Safety Switch Operation Checks: The following operational checks should be made daily.

a.Blade Clutch Switch: Sit in the operator’s seat. With both steering levers opened-out in the neutral position and the parking brake engaged, turn the blade clutch switch “on” and try to start the engine. The engine should not start. If it does, the blade clutch switch must be replaced. If the engine does not start, turn the blade clutch switch “off” and start the engine. Now turn the blade clutch switch “on” and the blades should rotate. If the blades do not turn, the blade clutch switch must be replaced, the seat switch must be replaced or the electric PTO clutch must be repaired.

b.Parking Brake Switch: Sit in the operator’s seat. With both steering levers opened-out in the neutral position and the blade clutch switch “off”, release the parking brake and try to start the engine. The engine should not start. If it does,
