10. The driveline should now be moved back and forth to 
ensure both ends are secured to the tractor PTO 
shaft and gearbox input shaft. Reattach any end that 
is loose.
Check Driveline Interference

Maximum PTO Driveline Movement During Operation

1.
Start tractor and raise cutter up just enough to 
remove support blocks. Remove support blocks.
2.
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.
3.
Raise and lower implement to find maximum 
extended driveline length. Check to make certain 
driveline does not exceed 25
o
 up or down.
4.
If needed, set tractor 3-point lift limiter to keep 
driveline from exceeding 25
o
 up.
Check Driveline Collapsible Length
Figure 1-8:
1.
Make sure driveline is properly installed and level 
before checking driveline collapsible length. (Refer to 
“Driveline Installation” instructions 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 1-8. If 
measurement is less than 1", then shorten driveline 
using instructions provided on right side of this page.
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.

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.
Driveline Shortening (Slip Clutch Driveline Shown)
Figure 1-8
Shorten Driveline
Be sure to check driveline collapsible length before 
shortening the driveline. If required, shorten driveline as 
follows:
Figure 1-8:
1.
Unhook 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 to the tractor and gearbox 
shafts.
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). 
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 to 
“Hook-up Driveline to Tractor PTO” instructions on 
page 12
