OPERATION These symbols may appear on your tractor or in literature supplied with the product. Learn and understand their meaning.
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 location of various controls and adjustments. Save this manual for future reference.
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. NOTE: Under certain conditions when tractor is standing idle with the engine running, hot engine exhaust gases may cause “browning” of grass.
OPERATION TO ADJUST GAUGE WHEELS (See Fig. 9) TO OPERATE ON HILLS 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. • Adjust mower to desired cutting height (See “TO ADJUST MOWER CUTTING HEIGHT” in the Operation section of this manual).
OPERATION NOTE: Before starting, read the warm and cold starting procedures below. • Insert key into ignition and turn key clockwise to “START” position and release key as soon as engine starts. Do not run starter continuously for more than fifteen seconds per minute. If the engine does not start after several attempts, push choke control in, wait a few minutes and try again. If engine still does not start, pull the choke control out and retry.
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.
