DAILY MAINTENANCE
When operating the power rake, check the tractor
hydraulic system to be sure the level of hydraulic oil
is adequate. If necessary, add hydraulic oil as
recommended in your tractor operator’s manual.
Repair hydraulic oil leaks promptly to avoid loss of
oil and serious personal injury from escaping oil.
After every 10 hours of operation, check all hardware
and tighten where required.
WEEKLY MAINTENANCE
Lightly lubricate bearing at each end of the rollers (1-2
pumps). Use a lithium grease of #2 consistency with a
MOLY (molybdenum disulfide) additive for all locations.
Be sure to clean fittings thoroughly before attaching
grease gun. See Figure 3.
Lubricate all pivot points. Use a lithium grease of #2
consistency with a MOLY (molybdenum disulfide)
additive for all locations. Be sure to clean fittings
thoroughly before attaching grease gun. See Figure 3.
Check tire pressure. Maintain 60 psi cold.
Lubricate driveline universal joints.
MONTHLY MAINTENANCE
Inspect drive chain.
Inspect and clean safety decals. Replace if damaged.
(See “Safety Decals” section for location.)
Check oil level in chain case.
Check gearbox oil level.
QUARTERLY MAINTENANCE
Change oil in chain case and add 1.5 pints of 85W 140
wt. lube.
PRELIMINARY CHECK
The best maintenance is regular preventive checks,
particularly when the machine is new. Check that all
nuts and bolts are tight.
CHAIN MAINTENANCE
The drive chain should be inspected weekly. New
chain has a tendency to stretch, so it is necessary to
check the chain tension to prevent flopping around,
thus causing potential problems.
The adjustment for chain tension is in the chain case.
To tighten the chain, loosen jam nut (#63) and turn the
adjusting bolt (#61) clockwise until the chain is snug.
Let the spring give the desired tension.
NOTE:
The tension spring should be compressed to
4-3/4 inches for proper tension.
IMPORTANT
•
Replacement chain should be only high quality
original equipment chain for longer life.
When being stored for a long period or at end of season,
change the oil, adding EP 85W 140 wt. oil, and rotate
the roller several times allowing the chain to be coated
with oil, enhancing chain life. Rotate the roller
periodically to maintain lubrication.
SPROCKETS
Sprockets should be checked to be sure slotted hex
nut is tight, the cotter pin is in place, and the sprocket
cannot move on shaft.
PTO DRIVE LINES
Periodically check the yoke on both ends of the front
PTO to the tractor. Make sure the set screws/jam nuts
are tight and the yoke is not moving on the shaft. PTO
shafts and U-joints should be sparingly lubricated
weekly.
GEARBOX
The gearbox is almost maintenance-free, but should
be checked monthly to be sure that the oil level is
maintained at half full. EP 80-90 wt. gear lube is rec-
ommended for use in the gearbox. Oil should be
changed after the first 100 hours or 30 days of operat-
ing. Then, normal change intervals of 1,000 hours or
12 months of operation 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 corro-
sive contaminants.
It should be noted that the gearbox only exceeds its
thermal capacity when the oil temperature exceeds
200°F.
