ASSEMBLY, OPERATION, & MAINTENANCE INSTRUCTIONS

bolts for both right and left sides should be positioned
in the same adjustment hole. This allows the Tiller to till
the same depth on each side.
6) Raise the Tiller and remove the blocking.
Slip Clutch
Adjustment
The Slip Clutch is designed to slip so that the gearbox
and driveline are protected if the implement strikes an
obstruction.
A new slip clutch or one that has been in storage over
the winter may seize. Before operating the implement,
make sure it will slip by performing the following:
1. Turn off tractor engine and remove key.
2. Remove driveline from tractor PTO.
3. Loosen the cap screws to remove all tension from
the spring plate.
4. Hold clutch hub solid and turn shaft to make sure
clutch slips.
5. If clutch does not slip freely, dissemble and clean the
thrust plate faces, flange yoke, and clutch hub.
6. Reassemble clutch.
7. Finger tighten spring until it is against the thrust plate
of the clutch and then tighten each of the nuts by 1½ -
2 full rotations. Try the implement and watch for clutch
to slip. Adjust nuts another ½ turn as needed until
clutch stops slipping.
8. If clutch continues to slip when the spring is
compressed, check friction disc for excessive wear.
Disc are 1/8” thick when new. Replace discs after 1/16”
wear. Minimum disc thickness is 1/16”.
PTO Shaft
Modification
Read and thoroughly understand the following
instructions before attempting assembly. If you are
not comfortable making the necessary changes,
please refer this project to a qualified professional.
NOTE: Due to the many variations in tractor hitch
points and distances between equipment gearbox
input shaft and tractor PTO output shafts, some
combinations will require PTO shafts to be shortened.
If it is determined that this is the case, follow the
instructions in the following steps.
1. Raise and lower the Tiller in order to locate the
shortest distance between gearbox input shaft and
tractor PTO output shaft. With the Tiller in the shortest
distance position, shut down the tractor and secure
the tiller in place.
WARNING: If the Tiller is raised up so that the PTO
shaft is an an angle sharper than 35 degrees, PTO
MUST BE STOPPED!
2. Pull apart the PTO shaft and attach outer section to
tractor PTO shaft. NOTE: Be sure to pull on PTO shaft
section to ensure yoke has locked into place.
3. Place and hold inner PTO shaft section next to
outer section and check if PTO shaft is too long. Each
section should end approximately 3” short of reaching
the U-joint shield on the opposite section. If the shaft
is too long, measure 3” back from each U-joint shield
and mark the other shaft section. Be sure to do this for
both PTO shaft halves. NOTE:
Do not cut PTO shaft
sections at this time.
4. As in Step 3, hold PTO shaft sections together and
check for a minimum of 6” of overlap. If the PTO shaft
has been marked for cutting, the overlap is the distance
between the two marks. If the PTO shaft has less than
6” of overlap, DO NOT USE. Contact your authorized
dealer.
NOTE: If the PTO shaft is too long, see further
instructions below for sizing.
5. Apply multi-purpose grease to the outside of the
male (inner) PTO shaft section. Assemble PTO shaft
and install on Tiller and tractor.
6. Pull on tractor side of PTO shaft yoke to be sure it
has locked in place. Make certain PTO shaft shielding
is in place and good working condition.
7. The PTO shaft shield is a non-rotating design and
must be secured prior to use. Using the chain on each
yoke shield, attach to a fixed object on the tractor and
equipment ends so that the PTO shaft shield will not
rotate during operation.
WARNING
To install PTO shaft with Slip Clutch:
1) Remove bolt as shown.
2) Attach PTO shaft.
3) Line up hole and groove in shaft.
4) Reinsert and tighten bolt.
