LUBRICATION INFORMATION
1. Do not let excess grease collect on or around
parts, particularly when operating in sandy areas.
2. See Figure 10 for lubrication points and frequency
of lubrication based on normal operating condi-
tions. Severe or unusual conditions may require
more frequent lubrication.
3. Use a lithium grease of #2 consistency with a
MOLY (molybdenum disulfide) additive for all loca-
tions unless otherwise noted. Be sure to clean fit-
tings thoroughly before attaching grease gun. Two
good pumps of most guns is sufficient when the
lubrication schedule is followed.
CHAIN MAINTENANCE
The drive chain should be inspected every 50 hours.
New chain has a tendency to stretch, so it is necessary
to check the chain tension to prevent flopping around,
thus causing potential problems. Chain tension is pre-
set with the torsion spring. If the chain becomes exces-
sively loose, it may be necessary to remove one link
(two pitches). If unable to reassemble, add an offset
link to lengthen the chain.
NOTICE
■ Replacement chain should be only high quality
original equipment chain for longer life.
When being stored for a long period or at end of sea-
son, change the oil, adding .8 quarts #00 gear fluid,
and rotate the roller several times allowing the chain to
be coated with lubricant, enhancing chain life. Rotate
the roller periodically to maintain lubrication.
PTO DRIVE LINES
Periodically check the yokes on front PTO. Make sure
the bolts and nuts are tight and the yoke is not moving
on the shaft. PTO shafts and U-joints should be spar-
ingly lubricated monthly.
SPROCKETS
Sprockets should be checked to be sure hex bolt is
tight and the sprocket cannot move on the shaft.
QUALIFIED TECHNICIAN MAINTENANCE
GEARBOX LUBRICATION
The gearbox is almost maintenance-free, but should be
checked quarterly to be sure that the oil level is main-
tained at half full. Use plug located halfway up back
face of gearbox to check/fill oil. A high quality gear oil
with a viscosity index of 80W or 90W and an API ser-
vice rating of GL-4 or -5 is recommended for use in the
gearbox. Oil should be changed after the first 30 hours
or 30 days of operating. Then, normal change should
be adequate. In the case of seasonal usage, it is best
to change the oil at the end of the season to remove
moisture and corrosive contaminants.
BEARING LUBRICATION
Highest quality bearings are used on the tiller. Only tri-
ple-seal bearings are used on the rotor shaft, which
operates down in the dirt. Lubrication of the bearings
will vary considerably with conditions. As a rule, bear-
ings should be under-lubricated rather than over-lubri-
cated. Over-lubrication can cause seals to blow out.
NOTICE
■ Replacement bearings should be only high
quality original equipment bearings for longer life.
Install new complete bearing housing if needed or just
replace the bearing insert. The shafts should be
straight, free of burrs, and up to size. If shaft is worn,
replace it prior to completing assembly.
DRIVELINE LUBRICATION
1. Lubricate the driveline slip joint every 8 hours of
operation. Failure to maintain proper lubrication
could result in damage to u-joints, gearbox, and
driveline.
2. Lower tiller to ground, disconnect driveline from
tractor PTO shaft, and slide halves apart. Do not
disconnect the halves from each other.
3. Apply a bead of grease completely around male
half where it meets female half. Slide drive halves
over each other several times to distribute grease.
4. Apply one pump of grease to each driveline u-joint
grease fitting.
5. Apply one pump of grease to each of the plastic
driveline shield bearings.
6. If using a shear pin drive, lubricate the shear yoke
with grease to prevent galling.
