Replacing the Fuel Filter

An in-line filter is incorporated into the fuel line between
the fuel tank and carburetor (Figure 38). Replace the
filter every 800 hours or sooner if the fuel flow is
restricted. Be sure the arrow on the filter is pointing
away from the fuel tank.
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and
others and can damage property.
• Drain gasoline from the fuel tank when the
engine is cold. Do this outdoors in an open
area. Wipe up any gasoline that spills.
• Never smoke when draining gasoline, and
stay away from an open flame or where a
spark may ignite the gasoline fumes.
1. Close the fuel shut off valve, loosen the hose clamp
on the carburetor side of filter, and remove the fuel
line from the filter (Figure 38).

Electrical System
Maintenance

Servicing the Battery

Properly maintain the battery electrolyte and keep the
top of the battery clean. Store the machine in a cool
place to prevent the battery from running down.
Check the electrolyte level every 50 operating hours or,
if machine is in storage, every 30 days.
Battery electrolyte contains sulfuric acid which
is a deadly poison and causes severe burns.
• Do not drink electrolyte and avoid contact
with skin, eyes or clothing. Wear safety
glasses to shield your eyes and rubber gloves
to protect your hands.
• Fill the battery where clean water is always
available for flushing the skin.
Maintain the cell level with distilled or demineralized
water. Do not fill the cells above the bottom of the split
ring inside each cell.
Keep the top of the battery clean by washing it
periodically with a brush dipped in ammonia or
bicarbonate of soda solution. Flush the top surface with
water after cleaning it. Do not remove the fill caps while
cleaning the battery.
The battery cables must be tight on the terminals to
provide good electrical contact.
Incorrect battery cable routing could damage
the tractor and cables causing sparks. Sparks
can cause the battery gasses to explode,
resulting in personal injury.
• Always disconnect the negative (black)
battery cable before disconnecting the
positive (red) cable.
• Always connect the positive (red) battery
cable before connecting the negative (black)
cable.
If corrosion occurs at the terminals, disconnect the
cables, negative (-) cable first, and scrape the clamps and
