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 D H G E F B A Q M C J K L Fig. 3 Our tractors conform to the applicable safety standards of the American National Standards Institute.
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. ENGINE • Move throttle control (D) between half and full speed (fast) position.
OPERATION • Put attachment lift lever in desired cutting height slot. The cutting height range is approximately 1" to 4". The heights are measured from the ground to the blade tip with the engine not running. These heights are approximate and may vary depending upon soil conditions, height of grass and types of grass being mowed. • The average lawn should be cut to approximately 2-1/2" during the cool season and to over 3" during hot months.
OPERATION TO STOP MOWER BLADES • TO OPERATE ON HILLS Disengage attachment clutch control. CAUTION: Do not drive up or down hills with slopes greater than 15° and do not drive across any slope. CAUTION: Do not operate the mower without either the entire grass catcher, on mowers so equipped, or the deflector shield (S) in place (See Fig. 10). • • • S • • • Choose the slowest speed before starting up or down hills. Avoid stopping or changing speed on hills.
OPERATION SERVICE REMINDER/HOUR METER RESERVE FUEL VALVE OPERATION (See Fig. 13) Service reminder shows the total number of hours the engine has run and flashes to indicate that the engine or mower needs servicing.

MAINTENANCE DOCKING POSITION V-BELTS OIL DRAIN EXTENSION Check V-belts for deterioration and wear after 100 hours of operation and replace if necessary. The belts are not adjustable. Replace belts if they begin to slip from wear. TRANSAXLE MAINTENANCE The transmission fan and cooling fins should be kept clean to ensure proper cooling. Do not attempt to clean fan or transmission while engine is running or while the transmission is hot.
MAINTENANCE IN-LINE FUEL FILTER (See Fig. 19) DECK WASHOUT PORT (See Fig. 21) The fuel filter should be replaced once each season. If fuel filter becomes clogged, obstructing fuel flow to carburetor, replacement is required. • With engine cool, remove filter and plug fuel line sections. • Place new fuel filter in position in fuel line with arrow pointing towards carburetor. • Be sure there are no fuel line leaks and clamps are properly positioned. • Immediately wipe up any spilled gasoline.
SERVICE AND ADJUSTMENTS WARNING: TO AVOID SERIOUS INJURY, BEFORE PERFORMING ANY SERVICE OR ADJUSTMENTS: • Depress brake pedal fully and set parking brake. • Place attachment clutch in “DISENGAGED” position. • Turn ignition key to “STOP” and remove key. • Make sure the blades and all moving parts have completely stopped. • Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.
