SECTION 4: MAINTENANCE

Perform all maintenance procedures at the intervals
given in the instructions.
ENGINE MAINTENANCE
Engine maintenance procedures must be performed
at the intervals given in the following instructions.
Checking Engine Oil Level
Check engine oil level before each use as follows:
• Place the tractor on a flat surface and stop the
engine. Allow the engine to cool long enough for
the oil to drain into the engine sump.
• Clean the area around the oil dipstick/fill cap.
• Pull and remove the dipstick/fill cap and wipe the
oil off. Reinsert the dipstick into the tube and
push firmly into place. See Figure 23.

• Remove the dipstick and check the oil level. The
oil level should be up to, but not over, the 'F'
mark on the distick. See Figure 24.

• If the level is low, add oil of the proper type, up to
the 'F' mark on the dipstick. (Refer to the Recom-
mended Viscosity Chart below.) Always check
the level with the dipstick before adding more oil.

*
Use of synthetic oil having 5W-20 or 5W-30 rating is
acceptable up to 40°F.
**
Synthetic oils will provide better starting in extreme
cold (below -10°F)
IMPORTANT: Always maintain the proper oil level in
the crankcase. Never operate the engine with the oil
level below the 'L' mark or over the 'F' mark on the
dipstick.
Changing Engine Oil & Filter
Change the engine oil and oil filter after every 100
hours of operation.
• Run the engine for a short time to warm the
engine oil. The oil will flow more freely and carry
away more impurities.
• Locate the oil drain valve on the right side of the
engine. Pop open the protective cap on the end
of the oil drain valve to expose the oil drain port.
See Figure 23.
• 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 a capacity great enough to collect
the used oil (1.6 qts.;1.5 liters).
• Remove the dipstick/oil fill cap from the oil fill
tube.
• Push the oil drain valve in slightly, then rotate
counterclockwise and pull outward to begin
draining oil. See Figure 23.
• After draining the oil, remove the drain hose,
push the drain valve in and rotate clockwise to
lock in the closed position. Push the protective
cap back onto the drain valve.
• Remove the oil filter using an automotive type oil
filter wrench (Refer to Figure 23). Wipe the filter
adapter with a clean cloth.
• Place the new oil filter in a shallow pan with open
end up. Pour new oil, of the proper type, into the
center threaded hole. Stop pouring when the oil
reaches the bottom of the threads. Allow a few
minutes for the oil to be absorbed by the filter
material.
