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. STEERING WHEEL INSERT LOCK NUT TOOLS REQUIRED FOR ASSEMBLY A socket wrench set will make assembly easier. Standard wrench sizes are listed.
ASSEMBLY • • • • • Slowly move the motion control lever forward and slowly drive tractor off skid. • Apply brake to stop tractor, set parking brake and place motion control lever in neutral position. • Turn ignition key to "STOP" position. Continue with the instructions that follow. Mount rear of seat on slides using mounting bolts and lock washers as shown. Pull out on adjustment handle and slide seat all the way forward. Install front mounting bolts and lock washers.
ASSEMBLY 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. IMPORTANT: Check belt for proper routing in all mower pulley grooves. • Engage belt tension rod by pushing rod into locking bracket. INSTALL MOWER AND DRIVE BELT (See Figs. 6 and 7) Be sure tractor is on level surface and mower suspension arms are raised with attachment lift control. Engage parking brake.
ASSEMBLY ✓ CHECKLIST CHECK TIRE PRESSURE The tires on your tractor were overinflated at the factory for shipping purposes. Correct tire pressure is important for best cutting performance. • Reduce tire pressure to PSI shown in “PRODUCT SPECIFICATIONS” section of this manual. BEFORE YOU OPERATE AND ENJOY YOUR NEW TRACTOR, WE WISH TO ASSURE THAT YOU RECEIVE THE BEST PERFORMANCE AND SATISFACTION FROM THIS QUALITY PRODUCT. PLEASE REVIEW THE FOLLOWING CHECKLIST: ✓ All assembly instructions have been completed.
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.

MAINTENANCE TRACTOR MANDREL ASSEMBLY Always observe safety rules when performing any maintenance. BLADE CENTER HOLE BRAKE OPERATION 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). BLADE BOLT (SPECIAL) 02 54 4 STAR TIRES • Maintain proper air pressure in all tires (See “PRODUCT SPECIFICATIONS” section of this manual).
MAINTENANCE TO CHANGE ENGINE OIL (See Figs. 15 and 16) Determine temperature range expected before oil change. All oil must meet API service classification SG-SL. • Be sure tractor is on level surface. • Oil will drain more freely when warm. • Catch oil in a suitable container. • Remove oil fill cap/dipstick. Be careful not to allow dirt to enter the engine when changing oil. • Remove yellow cap from bottom fitting of drain valve and install the drain tube onto the fitting.
MAINTENANCE CLEAN AIR SCREEN IN-LINE FUEL FILTER (See Fig. 17) Air screen must be kept free of dirt and chaff to prevent engine damage from overheating. Clean with a wire brush or compressed air to remove dirt and stubborn dried gum fibers. See engine manual. 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.
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.
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 assembly 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. SUSPENSION ARM 01553 LIFT LINK ADJUSTMENT NUT FIG.

The motion control lever has been preset at the factory and adjustment should not be necessary. • Park tractor on level surface.
SERVICE AND ADJUSTMENTS TO START ENGINE WITH A WEAK BATTERY (See Fig. 29) REPLACING BATTERY (See Fig. 30) WARNING: Do not short battery terminals by allowing a wrench or any other object to contact both terminals at the same time. Before connecting battery, remove metal bracelets, wristwatch bands, rings, etc. Positive terminal must be connected first to prevent sparking from accidental grounding. WARNING: Lead-acid batteries generate explosive gases.
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. HOOD INTERLOCKS AND RELAYS HEADLIGHT WIRE CONNECTOR Loose or damaged wiring may cause your tractor to run poorly, stop running, or prevent it from starting. • Check wiring. See electrical wiring diagram in the Repair Parts section of this manual.
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.
