NOTE: This Operator's Manual covers several
models. Tractor features may vary by model.
Not all features in this manual are applicable to
all tractor models and the tractor depicted may
differ from yours.
Maintenance
Warning!
Before performing
any maintenance or repairs,
disengage the PTO, move the
drive control levers fully outward
in the neutral position engaging
the parking brake, stop the
engine and remove the key to
prevent unintended starting.
Lubrication
• Using a pressure lubricating gun,
lubricate the front caster wheel axles
with Cub Cadet 251H EP grease after
every 10 hours of service.
• Periodically lubricate all other pivot
points with a quality lubricating oil.
Engine
Refer to the Engine Operator's Manual for all
engine maintenance intervals, procedures,
specifications and instructions.
Changing the Engine Oil
Warning
! If the engine has
been recently run, the engine,
muffler and surrounding metal
surfaces will be hot and can
cause burns to the skin. Exercise
caution to avoid burns.
Maintain oil level as instructed in Engine
Operator's Manual. Be careful not to spill oil on
any of the belts.
To complete an oil change, proceed as follows:
1. Run the engine for a short time to warm
the engine oil. The oil will flow more
freely and carry away more impurities.
Use care to avoid burns from hot oil.
2. Locate the oil drain hose on the engine.
See Figure 4-1.
Figure 4-1
3. Remove the hose from the clip securing
it to the frame.
4. Route the free end of the oil drain hose
toward an appropriate oil collection
container with at least a 2.5 quart
capacity, to collect the used oil.
NOTE: Avoid getting oil on the muffler
when draining.

5. While holding the free end of the
oil drain hose over the oil collection
container, unscrew the square-head
hose plug from the end of the hose. See
Figure 4-1. Drain the engine oil into the
collection container.
6. After draining the oil, wipe any residual
oil from the oil drain hose. Thread the
square head plug into the drain hose
fitting and fully tighten the plug.
7. Refill the engine with new oil. Refer to the
Engine Operator's Manual for information
regarding the volume and weight of
engine oil.
8. Place the hose back into the clip securing it
to the frame.
Lubrication
Using a pressure lubricating gun, lubricate
all grease fittings and points as noted in the
Lubrication Chart on page 21 and refer to the
applicable figures below.
Figure 4-1

Figure 4-3
Lubricate all other pivot points with a quality
lubricating oil as noted in the Oil Chart.
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 life and 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.
