9.
Hook driveline safety chain on the tractor end of
driveline to the tractor. Re-latch safety chain to the
outer driveline shield.
10. Hook driveline safety chain on the cutter end of
driveline to the cutter. Re-latch safety chain to the
inner driveline shield.
11. Continue with “Check Driveline Collapsible
Length” below.
Check Driveline Collapsible Length
Refer to Figure 1-5:
1.
Make sure driveline is properly installed and level
before checking driveline collapsible length. (Refer to
“Driveline Installation” on page 10 if needed.)
2.
With driveline level, measure 1" (“B” dimension)
back from universal joint shield to end of outer
driveline shield as shown in Figure 1-5.
3.
If measurement is 1" or more, skip to “Check
Driveline Maximum Length” on right side of this
page. If measurement is less than 1", shorten
driveline using instructions provided below.
Shorten Driveline Length
Refer to Figure 1-5:
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 from tractor and gearbox shafts.
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).
IMPORTANT: Two small chains are supplied with
the driveline. To keep driveline shields from rotating,
these chains must be attached to the outer and inner
driveline shields and to the cutter and tractor.
IMPORTANT: A driveline that is too long can
bottom out causing structural damage to tractor and
cutter. 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.

7.
Remove all burrs and cuttings.

Continue with “Check Driveline Maximum Length”
below.
Check Driveline Maximum Length
Refer to Figure 1-6:
The driveline maximum allowable length must, when fully
extended, have a minimum overlap of profile tubes by not
less than 1/2 the free length with both inner and outer
profile tubes being of equal length.
1.
Apply multi-purpose grease to the inside of the outer
shaft and reassemble the driveline.
2.
Assemble the two driveline profiles together with just
1/2 overlapping of the profile tubes as shown below.
Once assembled, measure and record the maximum
allowable length for future reference.
