Slip Clutch Run-In
Figure 4-1
CAUTION
!
To avoid minor or moderate injury:
Slip clutches that have been in use or have been slipped for
only two or three seconds during run-in may be too hot to
touch. Allow a hot clutch to cool before working on it.
Clutch Run-In
Refer to Figure 4-1:
1. Make sure the area is clear of all bystanders and
implement is safe to operate.
2. Using a pencil or other marker scribe a line across the
exposed edges of the clutch plates and friction disks.
3. Carefully loosen each of the 8 spring retainer nuts by
exactly 2 revolutions. It will be necessary to hold the
hex end of the retainer bolt in order to count the exact
number of revolutions.
4. Start tractor and engage power take-off drive for 2-3
seconds to permit slippage of the clutch surfaces.
Disengage power take-off, then re-engage a second
time for 2-3 seconds. Disengage power take-off, shut
off tractor, and remove key. Wait for all components to
stop before dismounting from tractor.
5. Inspect clutch and ensure that the scribed markings
made on the clutch plates have all changed position.
Slippage has not occurred if any two marks on the
friction disk and plate are still aligned. A clutch that
has not slipped must be disassembled to separate
the friction disk plates. See Clutch Disassembly,
Inspection & Assembly on page 25.
6. Allow clutch to cool to ambient temperature and
tighten each of the 8 spring retainer nuts on the
clutch housing exactly 2 revolutions to restore clutch
to original setting pressure.
•
If revolutions were not counted, refer to Figure 4-3
on page 25 to set spring length.
7. Clutch is now ready for use.
8. Check clutch during the first hour of operation and
periodically each week. An additional set of scribe
marks can be added to check for slippage.

Maintenance
Proper servicing and adjustments are key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly downtime and repair.
Check all hardware after several hours of operation and
regularly thereafter to ensure they are tight and secured.
Replace worn, damaged, or illegible safety labels by
obtaining new labels from your Land Pride dealer.
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 the hydraulics is off.
WARNING
!
To avoid serious injury or death:
•
Make sure controls are all in the neutral position or park
before starting the power machine.
•
Perform scheduled maintenance. Check for loose
hardware, missing parts, broken parts, structural cracks,
and excessive wear. Make repairs before putting the
implement back into service.
•
Always shut tractor down using “Tractor Shutdown
Procedure” provided in this manual before servicing,
adjusting, cleaning, or maintaining this implement.
•
Do not alter implement or replace parts on the implement
with other brands. Other brands may not fit properly or
meet OEM (Original Equipment Manufacturer)
specifications. They can weaken the integrity and impair the
safety, function, performance, and life of the implement.
Replace parts only with genuine OEM parts.
•
Buildup of debris around moving components and
gearboxes is a fire hazard. Keep rotating parts and
gearboxes free from debris.
•
Improper oil level can cause bearing failure and be a fire
hazard. Maintain proper gearbox oil level.
Slip Clutch Maintenance
The Powered Rake drive components are protected from
shock loads by a friction slip clutch. The clutch must be
capable of slippage during operation to protect the
gearbox, driveline, and other drivetrain parts. Friction
clutches should be “run-in” prior to initial operation and
after long periods of inactivity to remove any oxidation
that may have accumulated on the friction surfaces.
Repeat “run-in” instructions at the beginning of each
season and when moisture and/or condensation seizes
the inner friction plates.
