SERVICE (Continued)
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 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 is wom 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.

pedal slowly as you roll the mower. There should be
a place where the CLUTCH is disengaged and the
brakes not yet applied, allowing the machine to roll.
This should occur in the first half of the pedal travel.
4. 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 be-
- come slack. To regain correct belt tension, follow steps
ible emergencies. Normally, the mower should stop
from top forward speed within approximately three
feet after the CLUTCH/BRAKE pedal has been fully
depressed.
To adjust the braking action: !
Loosen Locknut and adjust the cable housing toward '
the rear of the mower to increase cable tension. See'
