ASSEMBLY Your new tractor has been assembled at the factory with exception of those parts left unassembled for shipping purposes. To ensure safe and proper operation of your tractor all parts and hardware you assemble must be tightened securely. Use the correct tools as necessary to insure proper tightness. TOOLS REQUIRED FOR ASSEMBLY STEERING WHEEL INSERT A socket wrench set will make assembly easier. Standard wrench sizes are listed.
ASSEMBLY INSTALL SEAT (See Fig. 3) TO DRIVE TRACTOR OFF SKID (See Operation section for location and function of controls) Adjust seat before tightening adjustment knob. • Remove adjustment knob and flat washer securing seat to cardboard packing and set aside for assembly of seat to tractor. • Pivot seat upward and remove from the cardboard packing. Remove the cardboard packing and discard. • Place seat on seat pan so head of shoulder bolt is positioned over large slotted hole in pan.
ASSEMBLY • • For ease of mower to tractor assembly, raise gauge wheels to highest position and retain with clevis pins and spring retainers. Adjust gauge wheels before operating mower. See “TO ADJUST GAUGE WHEELS” in the Operation section of this manual. • If equipped, turn height adjustment knob counterclockwise until it stops. • Lower mower linkage with attachment lift control. • Install belt into electric clutch pulley groove. • Place the suspension arms on outward pointing deck pins.

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 locations of various controls and adjustments. Save this manual for future reference.
OPERATION 00155 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. HOW TO USE YOUR TRACTOR 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) ATTACHMENT LIFT LEVER HIGH POSITION ATTACHMENT CLUTCH SWITCH PULL OUT TO "ENGAGE" 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 CAUTION: Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season.
OPERATION AUTOMATIC TRANSMISSION WARM UP • Before driving the unit in cold weather, the transmission should be warmed up as follows: • Be sure the tractor is on level ground. • Place the motion control lever in neutral. Release the parking brake and let the clutch/ brake slowly return to operating position. • Allow one minute for transmission to warm up. This can be done during the engine warm up period.

SERVICE AND ADJUSTMENTS • Position front plate assembly between front mower brackets. Raise deck and plate assembly to align holes and insert flanged pins. Secure pins with double loop retainer springs between the plate and mower brackets. NOTE: To assist in locating hole in flanged pin, the hole in pin is inline with notch on head of pin. If necessary, move mower side-to-side to give space between plate and mower brackets. FRONT-TO-BACK ADJUSTMENT (See Figs.
