3. 4. 5. 1. 2. OPERATINGTHE ENGINE LIFTING THE HOOD Pull the choke control button all the way out. More or less choking may be necessary due to variations in temperature, grade of fuel, etc. Little or no choking will be needed when the engine iswarm. The tractor hood is arranged to swing up and forward to make the engine and fuel tank readily accessible.
The ~ FUEL SYSTEM This engine is designed to operate on leaded gasoline with a 93 minimum octane rating or on unleaded or low lead gasoline with a 91 minimum octane rating (Research Method). use of unleaded gasoline will lengthen spark plug and valve life, maintain engine performance longer, and reduce rust and corrosion of engine wh ile stored. The fuel tank filler cap has an air vent. Keep the vent open at all times to assure proper flow of thefuel.
11 FUEL SYSTEM CARBURETOR ADJUSTMENTS -Continued A CAUTION! Be sure the brake pedal is in the locked position, transmission is in neutral, and the mower is disenga~d before adjusting the carburetor. If the engine shows a sooty exhaust and is sluggish under load, the high speed mixture is too rich. The high speed adjustment screw must be turned clockwise 1/4 turn at a time until the condition is corrected.
Retighten the cap screws after the seat is adjusted. NOTE: The battery is located in a well under the operator's seat for ease in servicing or replacement when necessary. CLUTCH AND BRAKE PEDAL Brake pedal lock in the engaged position. Adjusting the seat. LOCKING THE BRAKE Always lock the brake when the tractor is parked on a grade. To lock the brake, press down on the pedal; then place the brake pedal lock in the engaged position.
InternationalCub Cadet86, 108 and 128 Tractors CLUTCH-BRAKE free the tractor by speeding up the engine and suddenly engaging the clutch. Try backing out instead of going forward. PEDAL The combination clutch-brake pedal is used to disengage the engine from the transmission when shifting gears and to actuate the brake to stop the tractor. The pedal must be pressed all the way down to activate the safety starting switch when starting the engine. Do not carry passengersor give rides.

ENGINE COOLING This tractor has an air cooled engine. Air must be able to circulate freely around the engine, through the screen, shroud, and over the fins of the cylinder head and cylinder block. Keep these areas free of accumulated dirt and trash or engine will overheat and result in damaged moving parts. Periodic cleaning with compressed air will keep area clear for adequate cooling. Incoming air for combustion is filtered by a dry-type air cleaner having a filter element inside of the cover.
ELECTRICAL SYSTEM CHARGE INDICATOR Be sure the gasket is in good condition. Tighten the plug 1/2 to 3/4 turns past tiger tight. This instrument indicates whether the motorgenerator is charging or the battery is discharging. If it shows discharge continuously, investigate the cause to avoid completely discharging the battery and possible damage to the motor-generator. Replace a defective plug with a new plug.
ELECTRICAL SYSTEM MOTOR-GENERATOR BELT -Continued Adjusting the Motor-Generator Belt Loosen the motor-generator brace bolt and mounting bolts. Move the generator away from the engine until the tension on the belt is correct. NOTE: Under no circumstances should a pry bar be used on the motor-generator to obtain belt tension as damage to the bearings will result. VOLTAGE REGULATOR A satisfactory generator charging rate is maintained by the voltage regulator.
ELECTRICAL SYSTEM When replacing a battery, make certain the ground cable is connected to the negative (-) terminal on the battery. Be sure the rubber boot is properly positioned over the positive (+) terminal on the battery. NOTE: Both cables must be assembled with the nuts to the inside of the terminals to prevent shorting against fender well. CAUTION! If the rider is to be tipped up or on its side remove the batteries to avoid spilling the electrolyte.
PNEUMATIC CARE OF TIRES TIRES MOUNTING TIRES ON THE RIM Avoid stumps, stones, deep ruts, curbs, and other hazards. Cuts in tires should be repaired immediately as neglect decreases the tire life. After mounting a new or old tire on the rim, inflate it to 20 pounds pressure to seat the tire bead on the rim flange. Then deflate the tire to the correct operating pressure. Keep tires free from oil and grease as both destroyrubber.
FRONT QUICK ATTACHING LATCH This latch is used for front and center mounted equipment. Refer to the equipment manual for proper instructions. FRONT WHEEL TOE-IN Tie rod and drag link ball joints. The front wheel toe-in dimension is approximately 1/8-inch closer in front than in the rear. To measure for proper toe-in, make a chalk mark on the centerline of each tire the same height from the ground as the front wheel hubs.
International Cub Cadet 86, 108 and 128 Tractors Push the pedal down until the clutch just begins to release. This can be checked by shifting the transmission into third gear and rocking the tractor back and forth. If the drive shaft turns free and does not turn the engine, the clutch is disengaged. Locate the pedal at this point with a "c" clamp and adjust the jam nuts on both brake rods until the brakes just begin to clamp the brake discs and create some drag.
CLUTCH-BRAKE ADJUSTING THE BRAKES -Continued To adjust the brakes block the front wheels securely and raise the tractor so the rear wheels are off the ground. A CAUTION! Be careful and take necessary precautions when raising tractor off the ground.

8. 9. 4. 6. Cleanthe exterior of the engine. When your tractor is not to be used for some time, it should be stored in a dry and protected place. Leaving your tractor out-doors, exposed to the elements materially shortens its life. 7. Remove the battery and place it in a cool, dry place above (+32°F.). Check battery at leastonce a month for water level and amount of charge. See pages24 and 25. Follow the procedure outlines below when storing a tractor for an extended period of time. 1.
