Move the throttle lever back to the medium or “SLOW” position. 2. Flip the toggle switch to the “ON” position. 3. Advance throttle to operating speed (full speed). 4. The operator must remain in tractor seat at all times. If operator should leave tractor seat without turning off the power take-off switch, the engine will automatically shut off. 5.

FRONT PTO CLUTCH BREAK-IN PROCEDURE To break-in the components and increase the life of the clutch assembly, proceed as follows. 1. Attach mowing deck, snow thrower, etc. to the tractor. 2. Adjust the belt tension as recommended in attachment owner's manual. 3. Engage and disengage the PTO ten to fifteen times without any load (not cutting grass, not blowing snow, etc.). ADJUSTMENTS ADJUSTING THE SEAT Before starting the tractor, adjust the seat to the most comfortable driving position. Tilt the seat forward over the steering wheel, loosen the four cap screws in the seat support, and slide the seat assembly forward or rearward to the position which is most comfortable for the operator. See figure 14. FIGURE 14. Retighten the cap screws after the seat is adjusted NOTE: The battery is located in a well under the operator's seat for ease in servicing or replacment when necessary. ADJUSTING THE POWER TAKE-OFF CLUTCH The clutch is factory adjusted and should not require further adjustment under normal operating conditions. However, if the clutch fails to operate properly check as follows: Check fuse on pedestal. A CAUTION To avoid possible injury, alwasy disengage all clutches, move speed control into neutral, depress the brake, set the brake pedal lock and turn the ignition "OFF” before working on the machine. Using a feeler gauge, check the air gap See figure 15. Insert feeler gauge into one of three access slots located around the outside of the brake plate. The air gap should be .010-.015-inches. Adjust the self-locking nuts to obtain the proper clearance. Repeat the operation in all three access slots NOTE: If brake plate drags on clutch at .010-.015-inches air gap, increase air gap to .020-inches. If the above procedure does not work see your authorized dealer. 12 FIGURE 15. 1. Access slots 2. Brake plate 3. Self-locking nuts ADJUSTING THE BRAKES During normal operation of this machine, the brakes are subject to wear and will require periodic examination and adjustment. With the brake pedal disengaged, remove the clevis pinned end of one of the brake rod assemblies from the jackshaft assembly by removing the cotter pin from the clevis pin. See figure 16. FIGURE 16. Thread the clevis onto the brake rod one turn. Reconnect the clevis to the jackshaft assembly. There should be a minimum amount of clearance (no drag) between the brake pads and the rotor. See figure 17. If not, repeat adjustment as necessary. FIGURE 17. NOTE: Figure 17 is shown with the wheel and fender assembly removed for clarity. Repeat the adjustment on the brake rod assembly on the other side of the tractor. Recheck brake adjustment and insure proper brake operation before operating the tractor. WHEEL ALIGNMENT The front wheels should toe-in approximately 1/8". Measure the distances A and B on the front wheels. See figure 18. NOTE: Dimension B should be approximately 1/8 inch less than dimension A. FIGURE 18. Front wheel adjustments. To adjust the toe-in remove one ball joint, loosen the lock nut “C” at the ball joint and turn the tie rod ball joint in or out as required. 13 The carburetor is adjusted at the factory and under normal operating conditions it will not require readjusting. However, if the engine does not operate properly, what may appear to be a faulty carburetor adjustment is in many cases a clogged air filter. This possibility should be ruled out before attempting to readjust carburetor. Refer to “MAINTENANCE.” NOTE: To prevent possible damage to the carburetor needles, be very careful closing the carburetor needles before basic adjustments are made. Improper adjustment of the carburetor may result in engine damage. FIGURE 19. Tie rod and drag link ball joints. TURNING RADIUS The front wheels should have an equal angle lor left and right turns. If adjustment is necessary, remove ball joint and loosen lock nut “D," turn the drag link ball joint clockwise or counterclockwise as required See figure 19. ...
