Battery Charging
DANGER
BATTERIES PRODUCE EXPLOSIVE GASES
• Charge the battery in a well-ventilated
area, so that gases produced while charg-
ing can dissipate.
• Keep sparks, ames, and smoking mate-
rials away from the battery at all times.
• Make sure the battery cap vents are
open after the battery is lled with acid
(check manifold vent on each cap).
• Make sure the battery charger is un-
plugged before connecting or disconnect-
ing cables to the battery.
1.
 Charge the battery at 15 amps for 10 minutes.
DO NOT exceed 20 amps maximum recom-
mended charging rate. Charge until specic
gravity is at least 1.250. Total charging time
should not exceed one (1) hour.
2. After charging the battery, adjust the electrolyte
level to the bottom of the vent wells [1/4 to 1/2 in.
(6 to 13 mm) above the plates].
IMPORTANT: DO NOT overll the battery.
Electrolyte will overow through the vented caps
onto parts of the machine and WILL result in se-
vere corrosion.
3. Install battery.
Mower Deck Assembly
Deck Caster Wheels Installation
1. Remove the bolt, nut, axle spacer tube, and
spacer washers from each deck caster wheel
fork.
NOTE: Spacer washers are used only when
the optional semi-pneumatic deck wheels
(8.25 x 2.75) are installed.
2. Fit the axle spacer tube through the wheel hub,
position the spacer washer on each side of the
hub (if used), and t the assembly into the wheel
fork.
3. Insert the 3/8-16 x 4-1/2 in. bolt through the
wheel fork with the bolt head to the outside and
install the 3/8-16 in. Keps nut.
4. Tighten the bolt and nut until the axle spacer
tube bottoms against the inside of the wheel
fork (will not turn) while the wheel and spacer
washers (if used) spin freely without binding.

5. Grease the caster wheel bearings and caster
pivot bearings - one grease tting for each
wheel and each pivot.
Deck Discharge Deector Shield Installation
(Side Discharge Models Only)
Attach the side discharge deector shield using two
(2) 3/8-16 x 1-1/4 in. bolts, 3/8-16 nylon insert lock-
nuts, and 3/8 in. wave spring washers. The wave
washers t between the two hinging surfaces. Tight-
en the nuts until the shield moves freely but is not
loose.
WARNING
DO NOT operate the machine without the
grass deector shield attached and in the
lowest possible position.
