This unit is equipped with safety interlock switches. These safety systems are present for your safety. Do not attempt to bypass safety switches, and never tamper with safety devices. Check their operation regularly. Operational SAFETY Checks TEST 1 --ENGINE SHOULD NOT CRANK IF: • Mower blades switch is ON, OR • Ground speed control levers are not in their START/PARK positions, OR • Parking brake lever is in DISENGAGE position. TEST 2 --ENGINE SHOULD CRANK IF: • Mower blade switch is OFE AND • Ground speed control levers are in their START/PARK positions, AND • Parking brake lever is in ENGAGE position. TEST 3 --ENGINE SHOULD SHUT OFF IF: • Operator rises off seat with the mower blade switch ON, OR • Operator rises off seat with the ground speed levers in DRIVE positions, OR • Operator rises off seat with the parking brake in DISENGAGE position, OR • Operator moves the left and/or right ground speed control lever out of its START/PARK position with the parking brake lever in ENGAGE position. TEST 4 --BLADE BRAKE CHECK The mower blades and mower drive belt should come to a complete stop within five seconds after the mower blade switch is turned OFE If mower drive belt does not stop within five seconds, contact your local author ized dealer. NOTE: Once the engine has stopped, the mower blade switch must be turned OFF, the ground speed control levers must be locked in their START/PARK positions, and the parking brake lever must be in the ENGAGE position in order to start the engine. WARNING If the unit does not pass a safety test, do not operate it. See your local authorized dealer. Under no circumstance should you attempt to defeat the purpose of the safety interlock system. 26 CHECK / ADJUST PTO CLUTCH WARNING To avoid serious injury, perform adjustments only with engine stopped, key removed and tractor on level ground. Service Interval: 200 Hours. The Power Take Off (PTO) clutch drives the mower blades. The PTO clutch is engaged and disengaged by the mower blade switch. Check the PTO clutch adjustment every 200 hours of operation. Also perform the following procedure if the clutch is slipping, will not engage, or if a new clutch has been installed. 1. Remove key from ignition switch and disconnect spark plug wires to prevent the possibility of accidental starting while the PTO is being adjusted. 2. Note the position of the 3 adjustment windows (A, Figure 28) in the side of the brake plate and the nylock adjustment nuts (B). 3. Insert a .012"-.015" (2,5-4 mm) feeler gauge (C) through each window, positioning the gauge between the rotor face and the armature face as shown in Figure 29. 4. Alternately tighten the adjustment nuts (B, Figure 29) until the rotor face and armature face just contacts the gauge. 5. Check the windows for an equal amount of tension when the gauge is inserted and removed, and make any necessary adjustments by tightening or loosening the adjustment nuts. NOTE: The actual air gap between the rotor and armature may vary even after performing the adjustment procedure. This is due to dimensional variations on component parts, and is an acceptable condition. 6. Check the mower blade stopping time. The mower blades and mower drive belt should come to a complete stop within five seconds after the electric PTO switch is turned off. If adjustment does not stop a mower braking problem, replace the electric PTO clutch. Figure 28. PTO Clutch Adjustment A. Adjustment Window (Qty. 3, one shown) B. Adjustment Nut (3) Figure 29.
