Lubrication
WARNING!
Before lubricating,
repairing, or inspecting, always
disengage PTO, set parking brake,
stop engine and remove key to
prevent unintended starting.
Pivot Points & Linkage
Lubricate all the pivot points on the drive
system, parking brake and lift linkage at least
once a season with light oil.
Wheels & Caster Pivots
Each of the front wheel axles, rims and caster
pivots are equipped with grease fittings (a).
Lubricate with a No. 2 multi-purpose grease
applied with a grease gun after every 25 hours of
tractor operation.

Figure 4-3
Cleaning & Lubricating the Spindle Pulleys
Once a month remove the belt covers to
remove any accumulation of grass clippings
from around the spindle pulleys and V-belt.
Clean more often when mowing tall, dry grass.
Every 25 hours, lubricate the deck spindles.
Remove the wing knobs (a) to remove the belt
covers (b), locate the spindle lube fitting and using
a grease gun, lubricate the spindles. The spindle
holds 2.3 ounces of grease. See Figure 4-4.

Tires
Check the tire air pressure after every 50 hours
of operation or weekly. Keep the tires inflated to
the recommended pressures. Improper inflation
will shorten the tire service lifeand produce an
uneven cut. See the tire side wall for proper
inflation pressures. Observe the following
guidelines:
•
Do not inflate a tire above the maximum
pressure shown on the sidewall of the tire.
•
Do not reinflate a tire that has been run flat
or seriously under inflated. Have it inspected
and serviced by a qualified tire mechanic.
Battery Information
WARNING!
• Should battery acid
accidentally splatter into the
eyes or onto the skin, rinse the
affected area immediately with
clean cold water. If there is any
further discomfort, seek prompt
medical attention.
• If acid spills on clothing, first
dilute it with clean water, then
neutralize with a solution of
ammonia/water or baking soda/
water.
• NEVER connect (or disconnect)
battery charger clips to the
battery while the charger is
turned on, as it can cause sparks.
• Keep all sources of ignition
(cigarettes, matches, lighters)
away from the battery. The gas
generated during charging can
be combustible.
• As a further precaution, only
charge the battery in a well
ventilated area.
• Always shield eyes and
protect skin and clothing when
working near batteries.
• Batteries contain sulfuric acid
and may emit explosive gases.
Use extreme caution when
handling batteries. Keep batteries
out of the reach of children.
Battery Maintenance
•
The battery is filled with battery acid and
then sealed at the factory. However, even a
“maintenance free” battery requires some
maintenance to ensure its proper life cycle.
•
Spray the terminals and exposed wire
with a battery terminal sealer, or coat
the terminals with a thin coat of grease
or petroleum jelly, to protect against
corrosion.
•
Always keep the battery cables and
terminals clean and free of corrosion.
•
Avoid tipping. Even a sealed battery will
leak electrolyte when tipped.
WARNING!
Batteries contain
sulfuric acid and may emit
explosive gases. Use extreme
caution when handling
batteries. Keep batteries out of
the reach of children.
Battery Storage
1.
When storing the tractor for extended
periods, disconnect the negative battery
cable. It is not necessary to remove the
battery.
2.
All batteries discharge during storage.
Keep the exterior of the battery clean,
especially the top. A dirty battery will
discharge more rapidly.
3.
The battery must be stored with a full
charge. A discharged battery can freeze
sooner than a charged battery. A fully
charged battery will store longer in cold
temperatures than hot.
4.
Recharge the battery before returning
to service. Although the tractor may
start, the engine charging system may
not fully recharge the battery.
Removing the Battery
1.
Slide the seat all the way forward.
2.
Remove the hex washer screw securing the
battery hold-down bracket to the frame.
Then flip the battery hold-down bracket up
to free the battery. See Figure 4-5
Figure 4-5
3.
Remove the hex cap screw and sems nut
securing the black negative battery lead
to the negative battery post (marked
NEG). Move the cable away from the
negative battery post.
4.
Remove the hex cap screw and sems nut
securing the red positive battery lead to
the positive battery post (marked POS).
5.
Carefully lift the battery out of the
tractor.
NOTE: On some models it may be
necessary to slide the battery left or
right to remove it.
6.
Install the battery by repeating the
above steps in the reverse order.
Using the Transmission Bypass Rods
If for any reason the tractor will not drive or you
wish to move the tractor, the two hydrostatic
transmissions are equipped with a bypass
rod that will allow you to manually move the
tractor short distances.
WARNING!
Do not tow the
tractor, even with the bypass rod
engaged. Serious transmission
damage will result from doing so.
1.
From the rear of the tractor, just inside
the two rear tires, locate the transmission
bypass rods. Refer to Figure 4-6.
