SERVICE (Continued)
BATTERY CHARGING The engine is equipped with a flywheel alternator to
charge the battery, Ifthe tractor is not run regularly, connect the battery to a charger monthly to maintain the specific gravity at 1.250 or higher. Ifthis reading falls below 1.175, the battery liquid may freeze when temp- eratures 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.
DRIVEN DISC SERVICE If the drive does not engage after extended use, it may
be that the driven disc is excessively worn and is not contacting the drive disc. The driven disc must be
replaced if the rubber iswom down to 1/16" above the
metal. Replacethe robber driven discwhen excessively
worn or unevenly worn. To replace, remove the rear
cover plate, shift the drive into neutral, remove the four nuts from the hub, remove the old disc and replace it with
new disc (see Figure 18). Refer to Page 15 for TRACTION LOSS ADJUSTMENT procedure.

MOWER SERVICE & ADJUSTMENTS" Keep the topside of the mower freeof grass cuttings.
Buildupof clippings could cause belt problems and also might present potential fire hazard especially when dryl 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 13). 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 awire brush and scraper. Make sure this isdone 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 doward 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 in order to determine
approximate amount of adjustment required.
i 5. Tighten BRAKE BAND by loosening jam nut and
turning T-nut, on end of eyeboit, clockwise 1 to 2 turns, or until brake band tightens. Make sure flanged lip on T-nut is positioned vertically to fit over top edge of anchor. See Figure 22.
