OPERATION KNOW YOUR TRACTOR READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR TRACTOR Compare the illustrations with your tractor to familiarize yourself with the locations of various controls and adjustments. Save this manual for future reference. P H D G E F N B C K A L M Fig. 6 Our tractors conform to the safety standards of the American National Standards Institute. (G) ROS “ON” POSITION - Allows operation of mower deck or other powered attachment while in reverse.
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 a wide vision safety mask over spectacles or standard safety glasses. 00155 HOW TO USE YOUR TRACTOR NOTE: Failure to move throttle control between half and full speed (fast) position, before stopping may cause engine to “backfire”.
OPERATION TO MOVE FORWARD AND BACKWARD (See Fig. 10) TO ADJUST GAUGE WHEELS (See Fig. 12) Gauge wheels are properly adjusted when they are slightly off the ground when mower is at the desired cutting height in operating position. Gauge wheels then keep the deck in proper position to help prevent scalping in most terrain conditions. NOTE:Adjust gauge wheels with tractor on a flat level surface.
OPERATION TOWING CARTS AND OTHER ATTACHMENTS WARNING: Backing up with the attachment clutch engaged while mowing is strongly discouraged. Turning the ROS "ON", to allow reverse operation with the attachment clutch engaged, should only be done when the operator decides it is necessary to reposition the machine with the attachment engaged. Do not mow in reverse unless absolutely necessary. Tow only the attachments that are recommended by and comply with specifications of the manufacturer of your tractor.
OPERATION BEFORE STARTING THE ENGINE TO START ENGINE (See Fig. 6) 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.
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.
