LUBRICATION
Lubricating the Tractor
Lubricate the tractor as shown in Figures 10 through
16. When a grease gun is shown, wipe the fitting clean,
apply two or three shots of lithium base automotive
grease, and wipe off excess grease. When an oil can is
shown, wipe the area clean, apply a few drops of SAE 30
weight oil, then wipe up drips or spills.
In general, linkage connections and other parts that have
partial rotational or sliding movement (pedal pivot points,
steering links, etc.) should be lubricated periodically with
SAE 30 weight oil. Avoid applying excessive amounts of
oil since this may cause a build-up of dirt and grass clip-
pings around the lubricated area, making subsequent
lubrication more difficult to accomplish.
Roller bearings, bushings, axles, rotating assemblies
with grease fittings, and mechanisms with exposed gear
teeth (steering gears) require periodic lubrication with
lithium grease.
When grease fittings are present, a manual or pneumatic
pressure-feed grease gun should be utilized to inject
enough grease through the fitting to fully permeate the
enclosed area containing the bearings or other moving
parts.
Plain bushings, bearings, axles without grease fittings,
and exposed gear teeth require the direct application of
grease to all wear surfaces. Use a small, clean applicator
brush or other means of applying and spreading the
grease evenly.
Special care should be taken with ball and roller bearings
to ensure that a liberal application of grease is applied to
the bearing rollers or balls, and both inner and outer
races or bearing and bearing cups.
