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 end of driveline over
gearbox input shaft. 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.
6.
Attach safety chain on the outer driveline shield to
the tractor frame to restrict outer shield from rotating.
Re-latch safety chain to outer driveline shield.
7.
Attach safety chain on the inner driveline shield to
the tiller frame to restrict inner shield from rotating.
Re-latch safety chain to inner driveline shield.
Check Driveline Collapsible Length
Refer to Figure 1-9:
1.
Make sure driveline is installed properly before
checking driveline collapsed length (Refer to
“Driveline Installation” on page 13).
2.
With driveline level, measure (“B” dimension) back
from universal joint shield to end of outer driveline
shield as shown in Figure 1-9.
a. If measurement is less than 1", shorten driveline.
b. If measurement is 1" or more, skip to “Check
Driveline Maximum Length” on page 15.
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.
NOTE: If driveline is too long to fit between tractor
and tiller, skip to “Shorten Driveline” on this page.
IMPORTANT: Two safety chains are supplied with
the driveline. These chains must be attached to the
driveline shields and to the rotary tiller and tractor to
restrict the shields from rotating.
IMPORTANT: A driveline that is too long can bottom
out causing structural damage to tractor and tiller.
Always check driveline collapsed length during initial
setup, when connecting to a different tractor, and
when alternating between using a quick hitch and a
standard 3-Point hitch. More than one driveline may
be required to fit all applications.
Shortening the driveline
Figure 1-9
Shorten Driveline
Refer to Figure 1-9:
Be sure to first check driveline collapsed length as
instructed above. If required, shorten driveline as follows:
1.
Un-hook driveline from tractor PTO shaft and pull
outer and inner drivelines apart.
2.
Reattach outer driveline to tractor PTO shaft. Pull on
inner and outer drivelines to be sure universal joints
are properly secured.
3.
Hold inner and outer drivelines parallel to each other:
a. Measure 1" (“B” dimension) back from outer
driveline universal joint shield and make a mark at
this location on the inner driveline shield.
b. Measure 1" (“B” dimension) back from the inner
driveline universal joint shield and make a mark at
this location on the outer driveline shield.
4.
Remove driveline and safety chains from tractor and
gearbox.
5.
Measure from end of inner shield to scribed mark
(“X” dimension). Cut off inner shield at the mark. Cut
same amount off the inner shaft (“X1” dimension).
6.
Measure from end of outer shield to scribed mark
(“Y” dimension). Cut off outer shield at the mark. Cut
same amount off the outer shaft (“Y1” dimension).
7.
Remove all burrs and cuttings.
8.
Apply multi-purpose grease to the inside of the outer
shaft and reassemble driveline.
9.
Attach driveline to tiller gearbox input shaft and
tractor PTO shaft. Refer to “Driveline Installation”
on page 13 for detailed instructions.
10. Continue with “Check Driveline Maximum Length”
on page 15.
