Check Driveline Collapsible Length
1.
Make sure driveline is properly installed and level
before checking driveline collapsible length. (Refer to
“Driveline Installation” instructions on page 12 if
needed.)
Refer to Figure 1-5:
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 Interference” on right side of this page. If
measurement is less than 1", shorten driveline using
instructions provided below.
Driveline Shortening
Figure 1-5
Shorten Driveline
Refer to Figure 1-5:
Be sure to first check driveline collapsible length 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 from tractor and gearbox shafts.
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.

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.
Reattach driveline to cutter and tractor. Refer
“Driveline Installation” instructions on page 12.
10. Continue with “Check Driveline Interference”
below.
Check Driveline Interference
Refer to Figure 1-6:
1.
Make certain driveline yokes and safety chains are
properly attached. See steps 12 -14 on page 12.
2.
Start tractor and raise cutter up just enough to
remove support blocks. Remove support blocks.
3.
Slowly engage tractor hydraulic 3-point control lever
to lower cutter while checking for sufficient drawbar
clearance. Move drawbar ahead, aside or remove if
required.
4.
Raise and lower implement to find maximum
extended driveline length. Check to make certain
driveline does not exceed 25
o
up or down.
5.
If needed, set tractor 3-point lift height to keep
driveline from exceeding 25
o
up.

IMPORTANT: Avoid premature driveline
breakdown. A driveline that is operating must not
exceed an angle of 25 degrees up or down while
operating 3-Point lift.
