Always wear safety glasses or eye shields while operating your tractor or performing any adjustments or repairs. We recommend a wide vision safety mask over spectacles or standard safety glasses. HOW TO USE YOUR TRACTOR with the engine running, hot engine exhaust gases may cause “browning” of grass.
OPERATION • • • • • Be sure tractor is on a flat level surface. Lower mower and adjust mower to desired cutting height. Remove retainer spring and clevis pin which secure each gauge wheel bar. Lower gauge wheels to ground. Raise gauge wheels slightly to align holes in bracket and gauge wheel bar and insert clevis pin. Gauge wheels should be slightly off the ground. Replace retainer spring into clevis pin.
OPERATION BEFORE STARTING THE ENGINE TO START ENGINE (See Fig. 8) When starting the engine for the first time or if the engine has run out of fuel, it will take extra cranking time to move fuel from the tank to the engine. • Be sure freewheel control is in the transmission engaged position. • Sit on seat in operating position, depress clutch/brake pedal and set parking brake. • Place motion control lever in neutral (N) position. • Move attachment clutch to “DISENGAGED” position.
OPERATION MOWING TIPS PURGE TRANSMISSION • CAUTION: Never engage or disengage freewheel lever while the engine is running. • To ensure proper operation and performance, it is recommended that the transmission be purged before operating tractor for the first time. This procedure will remove any trapped air inside the transmission which may have developed during shipping of your tractor.
