OPERATION The operation of any tractor can result in foreign objects thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating your tractor or performing any adjustments or repairs. We recommend standard safety glasses or a wide vision safety mask worn over spectacles. HOW TO USE YOUR TRACTOR GROUND DRIVE • To stop ground drive, depress brake pedal into full “BRAKE” position. TO SET PARKING BRAKE (See Fig.
OPERATION TO MOVE FORWARD AND BACKWARD (See Fig. 7) • The direction and speed of movement is controlled by the forward and reverse drive pedals. • Start tractor and release parking brake. • Slowly depress forward (K) or reverse (L) drive pedal to begin movement. Ground speed increases the further down the pedal is depressed. • The average lawn should be cut to approximately 2-1/2" during the cool season and to over 3" during hot months.
OPERATION • • S • • • Avoid stopping or changing speed on hills. If stopping is absolutely necessary, push brake pedal quickly to brake position and engage parking brake. To restart movement, slowly release parking brake and brake pedal. Slowly depress appropriate drive pedal to slowest setting. Make all turns slowly. TO TRANSPORT (See Figs. 3 and 12) When pushing or towing your tractor, be sure to disengage transmission by placing freewheel control in freewheeling position.
OPERATION BEFORE STARTING THE ENGINE TO START ENGINE (See Fig. 3) 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 brake pedal and set parking brake. • Move attachment clutch to “DISENGAGED” position. • Move throttle control to choke position.
OPERATION PURGE TRANSMISSION MOWING TIPS • 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.
