tractor off, and remove switch key.
Refer to Figure 1-5:
4. Remove tapered pin (#2) from slip-clutch (#8).
5. Unsnap access doors (#7) from gearbox cone (#6)
and rotate about the metal pin either up or down to
gain access to the gearbox input spline shaft.
6. Slide slip-clutch end of driveline onto gearbox input
shaft until holes in slip-clutch align with notch in
gearbox shaft.
7. Insert tapered pin (#2) and secure with removed
washer (#5) & hex nut (#4). Tighten hex nut to the
correct torque.
8. Move slip-clutch back and forth several times to
make sure it is locked onto gearbox shaft.
9. Replace access covers (#7).
10. Pull back on yoke collar (#1) and push driveline yoke
onto the tractor PTO shaft. Release pull collar and
continue to push driveline yoke forward until pull
collar locks in place.
11. Move driveline yoke back and forth several times to
make sure yoke is locked in place. If driveline yoke
will not lock in place, skip to “Check Driveline
Collapsible Length” on page 12.
12. Continue with “Check Driveline Collapsible
Length”.
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 11.)
Refer to Figure 1-6 on page 13:
2. With driveline level, measure (“B” dimension) back
from universal joint shield to end of outer driveline
shield as shown in Figure 1-6. If measurement is less
than 1", then shorten driveline using instructions
provided below.
3. Skip to “Check Driveline Maximum Length” on
page 13 if “B” dimension is 1" or more.
Shorten Driveline
Refer to Figure 1-6 on page 13:
Be sure to check driveline collapsed length first. If
required, shorten driveline.
1. Unhook driveline from tractor PTO shaft. Pull outer
and inner drivelines apart.
2. Reattach outer driveline to tractor PTO shaft. Pull on
inner and outer driveline yokes 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.
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.
