SECTION 8: SERVICE
Battery
The battery is sealed and is maintenance-free. Acid
levels cannot be checked.
Always keep the battery cables and terminals clean
and free of corrosive build-up.
After cleaning the battery and terminals, apply a
light coat of petroleum jelly or grease to both
terminals.
Always keep the rubber boot positioned over the
positive terminal to prevent shorting.
IMPORTANT:
If removing the battery for any reason,
disconnect the NEGATIVE (Black) wire from it’s
terminal first, followed by the POSITIVE (Red) wire.
When re-installing the battery, always connect the
POSITIVE (Red) wire its terminal first, followed by the
NEGATIVE (Black) wire. Be certain that the wires are
connected to the correct terminals; reversing them
could change the polarity and cause damage to your
engine’s alternating system.
Charging
If the unit has not been put into use for an extended
period of time, charge the battery with an automotive-
type 12-volt charger for a minimum of one hour at six
amps.
WARNING:
Batteries give off an explosive
gas while charging. Charge battery in a well
ventilated area and keep away from an open
flame or pilot light as on a water heater, space
heater, furnace, clothes dryer or other gas
appliances.
Fuses
Two fuses are installed in your tractor’s wiring harness
to protect the tractor’s electrical system from damage
caused by excessive amperage.
If the electrical system does not function, or your
tractor’s engine will not crank, first check to be certain
that the fuse has not blown.
One can be found under the hood mounted behind the
top of the dash panel on the support bar.
The other can be found under the seat mounted to the
inside of the tractor frame next to the battery tray. Pull
the fuse out and inspect it to determine if it is good or
blown.
WARNING:
Always use a fuse with the
same amperage capacity for replacement.
Cutting Deck Removal
To remove the cutting deck, proceed as follows:
Place the PTO lever in the disengaged (OFF)
position and engage the parking brake.
Lower the deck by moving the deck lift lever into the
bottom notch on the right fender.
On model LTX-1842, remove the PTO belt from
around the cutting deck’s center pulley. Refer to
Figure 14. On model LTX-2146, remove the PTO
belt from around the tractor’s engine pulley and
idler pulley(s). Refer to Figure 15.
Looking at the cutting deck from the left side of the
tractor, locate the deck support pin on the rear left
side of the deck.
Pull the deck support pin outward to release the
deck from the deck lift arm. See Figure 11.
Rotate the pin slightly toward the rear of the tractor
and release the pin into the hole provided.
Repeat the above steps on the tractor’s right side.
Move the deck lift lever into the top notch to raise
the deck lift arms up and out of the way.
Gently slide the cutting deck toward the front of the
tractor allowing the hooks on the deck to release
themselves from the deck stabilizer rod.
Gently slide the cutting deck (from the right side)
out from underneath the tractor.
Cutting Blades
WARNING:
Be sure to shut the engine off,
remove ignition key, disconnect the spark
plug wire(s) and ground against the engine to
prevent unintended starting before removing
the cutting blade(s) for sharpening or
replacement. Protect your hands by using
heavy gloves or a rag to grasp the cutting
blade.
WARNING:
Periodically inspect the blade
adapter and/or spindle for cracks or damage,
especially if you strike a foreign object.
Replace immediately if damaged
.
The blades may be removed as follows.
Remove the deck from beneath the tractor, (refer to
Cutting Deck Removal on page 24) then gently flip the
deck over to expose its underside.
Place a block of wood between the center deck
housing baffle and the cutting blade to act as a
stabilizer. See Figure 13.
Use a 15/16" wrench to remove the hex flange nut
that secures the blade to the spindle assembly. See
Figure 13.
