ChangingtheEngine011
The engine oil and oil filter should be changed after
every 50 hours of tractor operation.
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. Allow the tractor to cool and
use caution when removing
IMPORTANT:The oil filter should be changed at every
oil change interval.
To complete an oil change, proceed as follows:
Braining the Oil
Run the engine for a few minutes to allow the oil in the
crankcase to warm up. Warm oil will flow more freely
and carry away more of the engine sediment which may
have settled at the bottom of the crankcase. Use care to
avoid burns from hot oil.
• Pop open the protective cap on the end of the oil
drain valve to expose the drain port. See Figure 13.
• Remove the oil fill cap/dipstick from the oil fill tube.
• Push the oil drain hose (packed with this manual)
onto the oil drain port. Route the opposite end of
the hose into an appropriate oil collection container
with at least a 2.5 quart capacity, to collect the used
oil.
• Push the oil drain valve in slightly, then rotate
counterclockwise and pull outward to begin
draining oil.
NOTE: The oil drain valve is found on the left-hand
side of single cylinder engines and the right-hand side
of twin-cylinder engines.
After the oil has finished draining, push the oil drain
valve back in, rotate it clockwise to lock the valve
closed and re-cap the end of the oil drain valve to
keep debris from entering the drain port.
IMPORTANT: Always change the oil filter when
performing an oil change on your tractor's engine.
Changingthe Oil Filter
After draining the oil, proceed as follows:
NOTE: Refer to the ReplacementParts table found on
page 33 of this manual for the proper oil filter.
• Before removing the old oil filter, clean around its
base to prevent debris from entering the crankcase.
• Grasp the oil filter and remove it from the filter
adapter by turning it counterclockwise.
• Put a drop of oil on your fingertip and apply a light
coating to the gasket of the new oil filter.

the filter an additional 1/2 turn after the gasket first
makes contact.
Re-fillingthe Crankcasewith Oil
IMPORTANT: On models LT1042 & LT 1045, the engine
(with oil filter) has a capacity of 50.75 oz. (1.5 liters.).
On models LT1046 & LT 1050, the engine (with oil filter)
has a capacity of 57.5 oz. (1.7 liters). Do NOT overfill.
Always check the level on the dipstick as instructed on
page 19 before adding more oil.
NOTE: For the proper oil type, refer to the Oil
Temperature/Viscosity chart on page 19 of this manual.
• Clean the area around the oil fill tube to prevent
debris from entering the crankcase.
