Battery

Your mower is equipped with a maintenance
free battery and does not need servicing.
However, periodic charging of the battery with an
automotive type battery charger will extend its life.
• Keep battery and terminals clean.
• Keep battery bolts tight.
• See chart for charging times.

Corrosion and dirt on the battery and terminals
can cause the battery to lose power.
1. Lift the seat and rotate fully forward until
supported by the seat rod.

J bolts just enough that the battery mount
bracket slides down off the battery.
3. Using two 1/2" wrenches disconnect BLACK
battery cable then RED battery cable.
4. Carefully remove the battery from the mower

wire brush until shiny.

jelly.

WARNING! Do not short battery
terminals by allowing a wrench or other objects
to contact both terminals at the same time.
Before connecting battery, remove metal
bracelets, wristwatch bands, rings, etc.
Positive terminal must be connected first to
prevent sparks from accidental grounding.
IMPORTANT INFORMATION Do not try to
open or remove caps or covers. Adding or
checking level of electrolyte is not necessary.
Always use two wrenches for the terminal
screws.

Caster Wheels

Check every 200 hours. Check that wheels rotate
freely. Foam filled tires or solid tires will void the
warranty.
To replace, remove nut and caster bolt. Pull the
wheel out of the yoke and take care with the
spacer. Reinstall in reverse order. Tighten the
caster bolt and torque to 45 ft-lbs (61 Nm).
NOTE: Tire must rotate freely but axle spacers
must not. If wheels do not rotate freely take the
unit to the dealer for service.
