3. Insert shaft of mounting tube (#15) fully into
bearing (#10). Turn bearing eccentric locking collar
clockwise and then tighten set screw in locking collar.
4. Reattach rear roller arm (#16) to seeder panel with
1" clevis pin (#9) and 3/16" cotter pin (#8). Be sure to
bend one leg of cotter pin to secure it in place.
5. Insert stop pin (#7) in seeder bracket and secure with
hairpin cotter (#6).
6. Reattach scrapper bar (#5) to left and right rear roller
arms (#16) with 3/8"-16 x 1 1/4 GR5 hex head cap
screws (#4), flat washers (#3), lock washers (#2),
and hex nuts (#1).
7. Reattach packer chain (#6) or turnbuckle (#7) to rear
roller arm (#16) with remaining hardware.
Driveline Slip Clutches
!
DANGER
To avoid serious injury or death:
Always disconnect driveline from the tractor before servicing
the drivetrain and components powered by the drivetrain. A
person can become entangled in the drivetrain if the tractor is
started and the power take-off is engaged.
!
WARNING
To avoid serious injury or death:
A slip clutch that has been in use or has slipped for as little as
only two or three seconds during run-in may be too hot to
touch. Allow a hot clutch to cool before working on it.
Drive components are protected from shock loads with a
friction slip clutch. The clutch must be capable of
slippage during operation to protect the gearbox,
driveline and other drive train 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.
Refer to Figure 4-8 to determine which friction clutch your
seeder has. Follow "run-in" instructions on the following
pages for your specific clutch type.

Clutch Run-In
Refer to Figure 4-9 (View - A):
1. Using a pencil or other marker, scribe a line across the
exposed edges of the clutch plates and friction disks.
2. Tighten all 4 nuts uniformly until spring load is low
enough that the clutch slips freely with power take-off
engaged.
3. Make sure the area is clear of all bystanders and
machine is safe to operate.
4. Start tractor and engage power take-off for 2-3
seconds to permit slippage of 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 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" below.
Refer to Figure 4-9 (View - B):
6. If no two marks on the friction disk and plate are still
aligned, Turn all 4 nuts fully back.
7. Allow clutch to cool to ambient temperature before
operating again. Clutch is now ready for use.
8. The clutch should be checked during the first hour of
cutting and periodically each week. An additional set
of scribe marks can be added to check for slippage.
Clutch Disassembly, Inspection & Assembly
If clutch run-in procedure above indicates that one or more
of the friction disks did not slip, then the clutch must be
disassembled into separate friction disks.
IMPORTANT: Before proceeding, secure clutch
firmly in a vise or other clamping device to prevent
Type B Clutch
injury.
