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 INSERT A socket wrench set will make assembly easier. Standard wrench sizes are listed.

Remove the cardboard packing and discard. • Place seat on seat pan so head of shoulder bolt is positioned over large slotted hole in pan. • Push down on seat to engage shoulder bolt in slot and pull seat towards rear of tractor.
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.

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 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). • With mower in desired height of cut position, gauge wheels should be assembled so they are slightly off the ground. Install gauge wheel in appropriate hole with shoulder bolt, 3/8 washer, and 3/8-16 locknut and tighten securely. • Repeat for opposite side installing gauge wheel in same adjustment hole.
OPERATION TOWING CARTS AND OTHER ATTACHMENTS TO START ENGINE (See Fig. 4) Tow only the attachments that are recommended by and comply with specifications of the manufacturer of your tractor. Use common sense when towing. Too heavy of a load, while on a slope, is dangerous. Tires can lose traction with the ground and cause you to lose control of your tractor.
OPERATION MOWING TIPS PURGE TRANSMISSION • 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 TRAILING EDGE UP Always observe safety rules when performing any maintenance. MANDREL ASSEMBLY 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). LOCK WASHER STAR FLAT WASHER TIRES BLADE BOLT • Maintain proper air pressure in all tires (See “PRODUCT SPECIFICATIONS” section of this manual).
MAINTENANCE NOTE: The original equipment battery on your tractor is maintenance free. Do not attempt to open or remove caps or covers. Adding or checking level of electrolyte is not necessary. NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil.
MAINTENANCE AIR FILTER CLAMP Your engine will not run properly using a dirty air filter. Service air cleaner more often under dusty conditions. See Engine Manual. CLAMP ENGINE OIL FILTER FUEL FILTER Replace the engine oil filter every season or every other oil change if the tractor is used more than 100 hours in one year. FIG. 14 MUFFLER CLEANING Inspect and replace corroded muffler and spark arrester (if equipped) as it could create a fire hazard and/or damage.
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 SIDE-TO-SIDE ADJUSTMENT (See Figs. 16 and 17) • Raise mower to its highest position. • At the midpoint of both sides of mower, measure height from bottom edge of mower to ground. Distance “A” on both sides of mower should be the same or within 1/4" of each other. • If adjustment is necessary, make adjustment on one side of mower only. • To raise one side of mower, tighten lift link adjustment nut on that side.
SERVICE AND ADJUSTMENTS • TO CHECK BRAKE • Park tractor on a level, dry concrete or paved surface, depress clutch/brake pedal all the way down and engage parking brake. • Disengage transmission by placing freewhel control in “transmission disengaged” position. Pull freewheel control out and into the slot and release so it is held in the disengaged position. The rear wheels must lock and skid when you try to manually push the tractor forward.
SERVICE AND ADJUSTMENTS • • • Tighten adjustment bolt securely. Start engine and test. If tractor still creeps, repeat above steps until satisfied. MOTION CONTROL LEVER TO START ENGINE WITH A WEAK BATTERY (See Fig. 25) WARNING: Lead-acid batteries generate explosive gases. Keep sparks, flame and smoking materials away from batteries. Always wear eye protection when around batteries. NEUTRAL LOCK GATE If your battery is too weak to start the engine, it should be recharged.
SERVICE AND ADJUSTMENTS TO REMOVE HOOD AND GRILL ASSEMBLY (See Fig. 28) SEAT PAN • • • • Raise hood. Unsnap headlight wire connector. Stand in front of tractor. Grasp hood at sides, tilt toward engine and lift off of tractor. To replace, reverse above procedure.

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.
