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.
TO ADJUST GAUGE WHEELS (See Fig. 7) 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.
BEFORE STARTING THE ENGINE CHECK ENGINE OIL LEVEL • The engine in your tractor has been shipped, from the factory, already filled with summer weight oil. • Check engine oil with tractor on level ground. • Remove oil fill cap/dipstick and wipe clean, reinsert the dipstick and screw cap tight, wait for a few seconds, remove and read oil level.
PURGE TRANSMISSION CAUTION: Never engage or disengage freewheel lever while the engine is running. To ensure proper operation and performance, it is recom- mended 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 devel- oped during shipping of your tractor.
