Check Driveline Collapsible Length
1. With driveline attached only to the implement,
remove outer driveline (tractor end) from inner
driveline to separate the two profiles.
2. Park tractor and implement on a level surface.
3. Raise implement until gearbox input shaft is level
with tractor power take-off shaft.
4. Adjust implement laterally until implement’s gearbox
input shaft is in-line with the tractor’s power take-off
shaft.
5. Securely block implement at this height to keep the
unit from lowering.
6. With implement resting on the support blocks,
shutdown the tractor using
7.
Attach outer driveline to the tractor’s power take-off
shaft. Refer to steps 6-8 on page 22.
Refer to Figure 1-22:
8. Hold inner and outer drivelines parallel to each other
and measure dimension “A”. If dimension “A” is
greater than or equal to 1" (2.5 cm), skip to
Otherwise, continue with step 12.
9. Apply multi-purpose grease to the inside of the outer
shaft and reassemble the driveline.
10. Attach driveline to the implement and tractor. Refer to
11. If dimension “A” is less than 1" (2.5 cm), continue with
step 12 on this page.

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, and when connecting to a
different tractor. More than one driveline may be
required to fit all applications.
Shorten Driveline Length
Figure 1-23
Refer to Figure 1-23:
12. Shorten driveline as follows:
a. Measure 1" (2.5 cm) (
“B1”
dimension) back from
outer driveline shield and make a mark at this
location on the inner driveline shield.
b. Measure 1" (2.5 cm) (
“B2”
dimension) back from
the inner driveline shield and make a mark at this
location on the outer driveline shield.
13. Remove outer driveline from the tractor’s
power take-off shaft and inner driveline from the
implement’s gearbox shaft.
14. 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).
15. 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).
16. Remove all burrs and cuttings.
