Non-Drive Skid Shoe & Bearing
Refer to Figure 4-3:
1. Remove hex nut (#1), lock washer (#2), flat
washer (#3), and skid shoe (#4).
2. Lubricate bearing (#5). Refer to “Non-Drive Roller
End Bearing” on page 27 for type of lubrication and
frequency.
3. Inspect skid shoe and end cover (#4) for wear.
Replace skid shoe (#4) as needed to keep dirt away
from bearing.
4. Replace existing/new skid shoe (#4) with existing
3/8"-16 x 3" hex head bolts (#6), flat washers (#3),
lock washers (#2), and hex nuts (#1). Tighten hex
nuts to the correct torque.

cover for wear and replace as needed.

Long-Term Storage
Clean, inspect, service, and make necessary repairs to
the attachment when storing it for long periods and at the
end of the season. This will help ensure the unit is ready
for field use the next time you hook-up to it.
DANGER
!
To avoid serious injury or death:
Always secure equipment with solid, non-concrete supports
before working under it. Never go under equipment supported
by concrete blocks or hydraulics. Concrete can break,
hydraulic lines can burst, and/or hydraulic controls can be
actuated even when power to hydraulics is off.
1. Clean off any dirt and grease that may have
accumulated on the rake and moving parts. Scrape
off compacted dirt from the roller and then wash
surface thoroughly with a garden hose.
2. Check the roller spikes for wear and replace roller
and/or spikes if necessary.
3. Inspect the Powered Rake for parts out of
adjustment, loose, and damaged or worn.
•
Make required adjustments.
•
Tighten all loose hardware.
•
Replace damaged and worn parts as needed.
4. Repaint parts where paint is worn or scratched to
prevent rust. Ask your Kubota dealer for touch-up
paint. Paint is available in aerosol can, quarts, and
gallon sizes. See chart below.
5. Replace all damaged or missing decals.
6. Lubricate as noted in “Lubrication” on page 31.
7. A light coat of oil or grease may be applied to the
roller and to any exposed hydraulic cylinder rods to
minimize oxidation.
8. When needed, Change oil in the chaincase. See
“Change Oil in Chaincase” on page 29.
9. Store Powered Rake on a level surface in a clean, dry
place. Inside storage will reduce maintenance and
make for a longer rake life.
