Driveline Installation
Refer to Figure 1-8 & Figure 1-9:
The tiller driveline is coupled to the tractor and implement
shafts with either push pin couplers, pull collar couplers,
or a combination of both and with either a shear bolt or
slip clutch on the implement end for protection from
shock loads.
Always engage PTO at low engine rpm to minimize
start-up torque. Drivelines with friction slip clutches
must go through a “run-in” operation prior to initial
use and after long periods of inactivity. See “Driveline
Protection” on page 20 for detailed instructions on
maintaining the slip clutch.
If the Rotary Tiller is used on more than one tractor, an
additional driveline may be required - especially if a quick
hitch is used.
!
DANGER
Do not engage tractor PTO while hooking-up and unhooking
driveline or while someone is standing near the driveline. A
person’s body and/or clothing can become entangled in the
driveline resulting in serious injury or death.
!
WARNING
Do not use a PTO adaptor with a quick hitch. A PTO adapter
will increase strain on the tractor’s PTO shaft resulting in
possible damage to shaft and driveline.
!
DANGER
All guards and shields must be installed and in good working
condition at all times during tiller operation!
!
WARNING
Always disengage PTO, engage parking brake, shut tractor
engine off, remove switch key, and wait for tines to come to a
complete stop before dismounting from tractor.
!
WARNING
Do not over speed PTO or machine breakage may result. Some
tractors are equipped with multispeed PTO ranges. Be certain
your tractor’s PTO is set for 540 rpm.
IMPORTANT: The driveline must be lubricated
before putting it into service. Refer to “Lubrication”
on page 23 for detailed instructions.
IMPORTANT: Drivelines with friction clutches must
go through a “run-in” operation prior to initial use
and after long periods of inactivity.See “Driveline
Protection” on page 20 for detailed instructions.
IMPORTANT: If tiller is to be used on more than one
tractor, an additional driveline may be required -
especially if a quick hitch is used.

Refer to Figure 1-1 on page 9:
1.
Park tractor and tiller on a level surface. Raise tiller to
align gearbox input shaft level with tractor PTO shaft.
Securely block tiller at this height to keep unit from
lowering while attaching the driveline.
2.
Place gear selector in park, shut tractor engine off,
set park brake and remove switch key.
3.
Remove gearbox shaft protector from end of gearbox
shaft and slide slip clutch or shear bolt yoke end of
driveline (#9) over gearbox input shaft (#3). Secure
to gearbox with driveline yoke locking device.
4.
Slide other end of driveline over tractor PTO shaft.
Secure driveline with yoke locking device.
5.
Move driveline yokes back and forth to ensure both
ends are secured to the shafts. Reattach any yoke
that is loose.

IMPORTANT: The tractor’s PTO shaft and tiller
gearbox shaft must be aligned and level with each
other during installation of driveline. This alignment
is the shortest distance between the two shafts.
