Check the fuel system components frequently and replace any parts showing worn spots or cracks. See BATTERY SERVICE Check the battery once each month. Remove the caps and add distilled water as necessary to bring the level of the electrolyte up to about 3/32“ over plates in each cell. DO NOT FILL TO THE RINGS. Carefully reinstall battery caps. In freezing weather, charge the battery after adding water to thoroughly mix the water in the electrolyte. Keep the terminals and cables clean and tight and make sure the red boot (shown in Figure 6) remains in position over the positive (+) terminals. Always disconnect black cable from negative (-) terminal first and reconnect last! BATTERY CHARGING The engine is equipped with a flywheel alternator to charge the battery. If the tractor is not run regularly, connect the battery to a charger monthly to maintain the specific gravity at 1.250 or higher. If this reading falls below 1.175, the battery liquid may freeze when temperatures drop to around zero degrees F. To charge, connect per instructions furnished with charger. If time allows, slow charge at 1 amp for ten hours or as an alternate, fast charge at 3 amps for four hours. Observe all precautions while charging. TO ADJUST TIRE PRESSURE Check tire pressure at frequent intervals. A low tire on one side causes uneven mowing. Pressure in front tires should be maintained at 12 psi while rear tire pressure should be 10 psi. SERVICE (Continued) WHEEL BRAKE TEST & READJUSTMENT 1. Test the wheel braking action at frequent intervals to insure proper stopping in the event of possible emergencies. Normally, the mower should stop from top forward speed within approximately three feet after the NEUTRAL RETURN/BRAKE PEDAL has been fully depressed. 2. To adjust brake action: Turn locknut on brake rod clockwise to make braking more responsive. Turn locknut counterclockwise if slower braking action is desired. See Figure 19. LOCKNUT (TURN CLOCKWISE TO TIGHTEN BRAKES - COUNTERCLOCKWISE TO LOOSEN) FIGURE 19 3. After adjusting locknut, retest braking action as described in Step 1. MOWER DRIVE BELT ADJUSTMENT Normally, within the first few hours of operation, the MOWER DRIVE BELT will seat into the pulleys and become slack. To regain correct belt tension, follow Steps 1 thru 5. 1. Lower MOWER DECK to lowest position. 2. Push BLADE CONTROL LEVER downward to “OFF” position. 3. Remove BLADE CABLE SPRING from hole in BRAKE ARM. Reattach spring in next hole forward. See Figure 20. 4. Pull BLADE CONTROL lever up to "ON" position, then check belt tension. 5. If belt is still too slack, move spring forward another hole until tension is correct. FIGURE 20 MOWER DRIVE BELT SERVICE To install or replace the MOWER DRIVE BELT, follow Steps 1 thru 9. 1. 2. 3. 4. 5. 6. Lower MOWER DECK to lowest position. Loosen screw on slotted side of belt covers and swing covers away from pulleys. Loosen pulley screw on stationary IDLER PULLEY until BELT RETAINER can be moved away from belt. Loosen pulley screw on BRAKE ARM IDLER PULLEY until belt can be removed from between BELT RETAINER and PULLEY. Remove old belt. Route new belt around puileys as shown in Figure 21.

Tighten retaining screw. 9 SERVICE (Continued) MOWER SERVICE & ADJUSTMENTS Keep the topside of the mower free of grass cuttings. Buildup of clippings could cause belt problems and also might present potential fire hazard especially when dry. If uneven cutting is noted, check the tire pressure first as this is the most common cause. If tire pressure is correct and uneven cutting persists, move the tractor to a flat level surface, such as a garage floor, and check the deck level. (See “LEVELING MOWER”, Page 12). To prolong the life and efficiency of your mower, keep the underside of deck clean and free of accumulated grass clippings by washing it down with a hose and/or scraping with a wire brush and scraper. Make sure this is done at the end of the cutting season before placing the mower in storage. BLADE BRAKE ADJUSTMENT The BLADE BRAKE assembly is designed to stop blade rotation within 3 seconds after the BLADE CONTROL LEVER has been pushed downward to “OFF”. Should the blades not stop within 3 seconds, the BLADE BRAKE must be adjusted as follows: 1. Lower deck to lowest position. 2. Push BLADE CONTROL lever downward to “OFF" position. 3. Loosen retaining nut on R.H. OUTSIDE PULLEY BELT COVER and swing cover out of way. 4. Inspect BRAKE BAND closely to determine approximate amount of adjustment required. 5. Tighten BRAKE BAND by loosening jam nut and turning T-nut on end of eyebolt, clockwise 1 to 2 turns, or until BRAKE ...
