Check Driveline Minimum Length
Figure 1-7
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 the gearbox input shaft is level
and in-line with the tractor power take-off shaft.
4. Securely block implement at this height to keep unit
from lowering.
5. With implement resting on the support blocks, Shut
Refer to Figure 1-7:
6. Attach outer driveline to the tractor’s power take-off
shaft. Refer to steps 5-8 under
7.
Hold inner and outer drivelines parallel to each other
as shown and measure distance “A”.
•
If “A” is less than 1" (2.5 cm), continue with step 8.
•
If “A” is greater than or equal to 1" (2.5 cm), skip to
“Driveline Maximum Allowable Length”
22009
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.
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.
Driveline Shortening
Figure 1-8
Refer to Figure 1-8:
8. 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.
9. Remove outer driveline from the tractor power take-
off shaft and inner driveline from the implement’s
gearbox shaft.
10. 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).
11. 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).
12. Remove all burrs and cuttings.
