ASSEMBLY HOW TO SET UP YOUR TRACTOR INSTALL SEAT (See Fig. 3) PREPARE BATTERY (See Fig. 2) Adjust seat before tightening adjustment knob. • Remove cardboard packing on seat pan. • Place seat on pan and assemble shoulder bolt. • Assemble adjustment knob and flat washer loosely. Do not tighten. • Tighten shoulder bolt securely. • Lower seat into operating position and sit on seat. • Slide seat until a comfortable position is reached which allows you to press clutch/brake pedal all the way down.
ASSEMBLY INSTALL BATTERY (See Figs. 4 and 5) CAUTION: Do not short battery terminals. Before installing battery, remove metal bracelets, wristwatch bands, rings, etc. Positive terminal must be connected first to prevent sparking from accidental grounding. • • • • Lift seat to raised position. Open battery box door. Be sure battery drain tube is attached to battery box. Lower battery into battery box with battery terminals toward front of tractor.
ASSEMBLY ASSEMBLE GAUGE WHEELS TO MOWER DECK (See Fig. 7) DEFLECTOR SHIELD Assemble 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.

CUSTOMER RESPONSIBILITIES TRACTOR TO SHARPEN BLADE (See Fig. 15) Always observe safety rules when performing any maintenance. Care should be taken to keep the blade balanced. An unbalanced blade will cause excessive vibration and eventual damage to mower and engine. • The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower. • To check blade balance, you will need a 5/8" diameter steel bolt, pin, or a cone balancer.
CUSTOMER RESPONSIBILITIES BATTERY (See Fig. 16) TRANSAXLE COOLING Your tractor has a battery charging system which is sufficient for normal use. However, periodic charging of the battery with an automotive charger will extend it's life. • Acid solution level in each battery cell should be even with bottoms of vent wells. Add only distilled or iron free water if necessary. Do not overfill. • Keep battery and terminals clean. • Keep battery bolts tight.
CUSTOMER RESPONSIBILITIES ENGINE COVER KNOB AIR CLEANER COVER LUBRICATION WING NUT FOAM PRE-CLEANER Only use high quality detergent oil rated with API service classification SF or SG. Select the oil's SAE viscosity grade according to your expected operating temperature.
CUSTOMER RESPONSIBILITIES CLEAN AIR INTAKE/COOLING AREAS MUFFLER To insure proper cooling, make sure the grass screen, cooling fins, and other external surfaces of the engine are kept clean at all times. Every 100 hours of operation (more often under extremely dusty, dirty conditions), remove the blower housing and other cooling shrouds. Clean the cooling fins and external surfaces as necessary. Make sure the cooling shrouds are reinstalled.
SERVICE AND ADJUSTMENTS CAUTION: 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 "OFF" 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. TO REMOVE MOWER (See Fig.
SERVICE AND ADJUSTMENTS FRONT-TO-BACK ADJUSTMENT (See Figs. 23 and 24) TO LEVEL MOWER HOUSING IMPORTANT: DECK MUST BE LEVEL SIDE-TO-SIDE. IF THE FOLLOWING FRONT-TO-BACK ADJUSTMENT IS NECESSARY, BE SURE TO ADJUST BOTH FRONT LINKS EQUALLY SO MOWER WILL STAY LEVEL SIDE-TOSIDE. Adjust the mower while tractor is parked on level ground or driveway. Make sure tires are properly inflated (See “PRODUCT SPECIFICATIONS” on page 3 of this manual).
SERVICE AND ADJUSTMENTS TO REPLACE MOWER BLADE DRIVE BELT (See Fig. 25) ROTOR CLUTCH PLATE The mower blade drive belt may be replaced without tools. Park the tractor on level surface. Engage parking brake. BELT REMOVAL • Remove mower from tractor (See “TO REMOVE MOWER” in this section of this manual). • Work belt off both mandrel pulleys and idler pulleys. • Pull belt away from mower. .012" SLOT (3) BELT INSTALLATION • Install new belt in reverse order of removal.

CAUTION: Lead-acid batteries generate explosive gases. Keep sparks, flame and smoking materials away from batteries. Always wear eye protection when around batteries.
SERVICE AND ADJUSTMENTS TO REPLACE FUSE ENGINE Replace with 30 amp automotive-type plug-in fuse. The fuse holder is located in the engine compartment, directly in front of the dash. 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.
SERVICE AND ADJUSTMENTS TO ADJUST CARBURETOR (See Fig. 34) IDLE SPEED ADJUSTING SCREW The carburetor has been preset at the factory and adjustment should not be necessary. However, minor adjustment may be required to compensate for differences in fuel, temperature, altitude or load. If the carburetor does need adjustment, proceed as follows: In general, turning the adjusting needles in (clockwise) decreases the supply of fuel to the engine giving a leaner fuel/air mixture.
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. 00001 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.
