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. IMPORTANT: Check belt for proper routing in all mower pulley grooves. • If equipped, turn height adjustment knob counterclockwise until it stops. • Lower mower linkage with attachment lift control. • Install belt into electric clutch pulley groove.

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 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 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.

MAINTENANCE TRACTOR BLADE MANDREL ASSEMBLY CENTER HOLE Always observe safety rules when performing any maintenance. BRAKE OPERATION BLADE BOLT (SPECIAL) If tractor requires more than six (6) feet stopping distance at high speed in highest gear, then brake must be adjusted. (See “TO ADJUST BRAKE” in the Service and Adjustments section of this manual). STAR FIG. 13 TIRES • Maintain proper air pressure in all tires (See “PRODUCT SPECIFICATIONS” section of this manual).
MAINTENANCE • • • Disconnect BLACK battery cable first then RED battery cable and remove battery from tractor. Rinse the battery with plain water and dry. Clean terminals and battery cable ends with wire brush until bright. Coat terminals with grease or petroleum jelly. Reinstall battery (See “REPLACING BATTERY" in the SERVICE AND ADJUSTMENTS section of this manual).
MAINTENANCE IN-LINE FUEL FILTER (See Fig. 18) ENGINE OIL FILTER 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 clutch/brake pedal fully and set parking brake. • Place motion control lever in neutral (N) position. • 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.
SERVICE AND ADJUSTMENTS NOTE: Each full turn of nut “C” will change distance. “B” by approximately 3/16". • When distance “B” is 1/8" to 1/2" lower at front than rear, tighten nut “D” against trunnion on both front links. • To raise front of blade, loosen nut “D” from trunnion on both front links. Tighten nut “C” on both front links an equal number of turns. The two front links must remain equal in length.
SERVICE AND ADJUSTMENTS TO REPLACE MOWER DRIVE BELT TO REPLACE MOWER BLADE (SECONDARY) DRIVE BELT (See Fig. 25) MOWER DRIVE BELT REMOVAL (See Fig. 24) • Park tractor on a level surface. Engage parking brake. • Lower mower to its lowest position.

SERVICE AND ADJUSTMENTS TO CHECK AND ADJUST BRAKE (See Fig. 26) TO REPLACE MOTION DRIVE BELT (See Fig. 27) Your tractor is equipped with an adjustable brake system which is mounted on the right side of the transaxle. If tractor requires more than five (5) feet to stop at highest speed in highest gear on a level, dry concrete or paved surface, then brake must be checked and adjusted.
SERVICE AND ADJUSTMENTS TRANSAXLE MOTION CONTROL LEVER NEUTRAL ADJUSTMENT (See Fig. 28) TO REMOVE WHEEL FOR REPAIRS (See Fig. 29) The motion control lever has been preset at the factory and adjustment should not be necessary. • Loosen adjustment bolt in front of the right rear wheel, and lightly tighten. • Start engine and move motion control lever until tractor does not move forward or backward. • Hold motion control lever in that position and turn engine off.
SERVICE AND ADJUSTMENTS TO REPLACE HEADLIGHT BULB • • • • Raise hood. Pull bulb holder out of the hole in the backside of the grill. Replace bulb in holder and push bulb holder securely back into the hole in the backside of the grill. Close hood.

SERVICE AND ADJUSTMENTS ENGINE • TO ADJUST THROTTLE CONTROL CABLE (See Fig. 33) • The throttle control has been preset at the factory and adjustment should not be necessary. Check adjustment as described below before loosening cable. If adjustment is necessary, proceed as follows: • With engine not running, move throttle control lever to fast position. • Check that speed control lever is against stop screw. If it is not, loosen casing clamp screw and pull throttle cable until lever is against screw.
STORAGE Immediately prepare your tractor for storage at the end of the season or if the tractor will not be used for 30 days or more. ENGINE FUEL SYSTEM IMPORTANT: IT IS IMPORTANT TO PREVENT GUM DEPOSITS FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH AS CARBURETOR, FUEL FILTER, FUEL HOSE, OR TANK DURING STORAGE. ALSO, EXPERIENCE INDICATES THAT ALCOHOL BLENDED FUELS (CALLED GASOHOL OR USING ETHANOL OR METHANOL) CAN ATTRACT MOISTURE WHICH LEADS TO SEPARATION AND FORMATION OF ACIDS DURING STORAGE.
