Driveline Shortening
Figure 1-5
Check Driveline Collapsible Length
Refer to Figure 1-5:
IMPORTANT: A driveline that is too long can bottom
out causing structural damage to the tractor and
implement. Always check driveline minimum 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.
IMPORTANT: The power take-off shaft and gearbox
input shaft must be aligned and level with each other
when checking driveline minimum length. A driveline
that is too long can damage tractor and implement.
1. With driveline attached only to the cutter, remove
outer driveline (tractor end) from inner driveline to
separate the two profiles.
2. Park tractor and cutter on a level surface.
3. Raise cutter until gearbox input shaft is level with
tractor power take-off shaft. Securely block cutter at
this height to keep unit from lowering.
4. Shut tractor down without removing support blocks.
Refer to "Tractor Shutdown Procedure" on page
12.
5. Attach outer driveline to the tractor's power take-off
shaft. Refer to steps 5-7 under "Driveline Hook-Up"
on page 15.
6. Hold inner and outer drivelines parallel to each other.
If dimension "A" is greater than or equal to 1", then
skip to "Check Driveline Maximum Length" on
page 17. Otherwise continue with step 7.

Refer to Figure 1-6:
7. If dimension "A" was less than 1", shorten driveline as
follows:
a. Measure 1" ("B1" dimension) back from outer
driveline shield and make a mark at this location
on the inner driveline shield.
b. Measure 1" ("B2" dimension) back from the inner
driveline shield and make a mark at this location
on the outer driveline shield.
8. Remove outer driveline from the tractor power take-
off shaft and inner driveline from the cutter gearbox
shaft.
9. Cut off non-yoke end of inner driveline as follows:
a. Measure from end of inner shield to scribed mark
("X" dimension) and record.
b. Cut off inner shield at the mark. Cut same amount
off the inner shaft ("X1" dimension).
10. Cut off non-yoke end of outer driveline as follows:
a. Measure from end of outer shield to scribed mark
("Y" dimension) and record.
b. Cut off outer shield at the mark. Cut same amount
off the outer shaft ("Y1" dimension).
11. Remove all burrs and cuttings.
12. Continue with "Check Driveline Maximum Length"
on page 17.
