4. Slide outer yoke of driveline over tractor's PTO shaft
and secure with locking collar.
5. If driveline fits, skip to "Driveline Maximum Allowable
Length". if driveline does not fit, continue with step 6
below.
6. The driveline will require shortening if it is too long to
fit between tractor and Rotary Cutter. Shorten
driveline as follows:
a. Check to make sure cutter and tractor PTO shafts
are level with each other and the deck is securely
supported at this height with support blocks.
b. Pull driveline profiles apart into two sections as
shown in Figure 1-6.
c. Attach outer driveline universal joint to tractor
PTO shaft and inner driveline universal joint to
gearbox shaft. Pull on each driveline section to be
sure universal joints are secured.
d. Hold driveline sections parallel to each other to
determine if they are too long. The inner and outer
shields on each section should endapproximately
1" short of reaching the universal joint shield on
the adjacent section (see “B” dimension). If they
are too long, measure 1" (“B” dimension) back
from the universal joint shield and make a mark at
this location on the inner and outer shields.
e. Cut off inner shield at mark (“X” dimension). Cut
same amount off inner shaft (“X1” dimension).
Repeat cut off procedure (“Y”&“Y1” dimensions)
to cut outer driveline half.
f. Remove all burrs and cuttings.

Driveline Maximum Allowable Length
Be sure to check driveline minimum length before
checking driveline maximum allowable length.
Refer to Figure 1-7:
Driveline maximum allowable length, when fully
extended, must have a minimum overlap of profile tubes
by not less than 1/2 the free length with both inner and
outer profile tubes being of equal length.
Driveline Maximum Length
Figure 1-7
1. Measure and record driveline free length.
2. With the driveline profiles pulled apart, apply multi-
purpose grease to the inside of the outer profile and
reassemble the two profiles.
3. Move driveline halves together until profile tubes
overlap by 1/2 the free length. Measure and record
maximum allowable length shown in Figure 1-7.
4. Attach inner driveline yoke to gearbox shaft and
outer driveline yoke to tractor's PTO shaft.
5. The driveline should now be moved back and forth to
insure that both ends are secured. Reattach any end
that is loose.
6. Hook a safety chain in the hole on the outer driveline
yoke shield and its opposite end to the tractor.
7. Hook the other safety chain in the hole on the inner
driveline yoke shield and its opposite end to the
cutter.
8. Start tractor and raise Rotary Cutter just enough to
remove support blocks from under the cutter deck.
9. Slowly engage tractor’s 3-point controls to lower
cutter. Check for sufficient drawbar clearance. Move
drawbar ahead, aside or remove if required.
10. Raise and lower implement to find the maximum
possible extended driveline length. Check to make
certain that the driveline has not extended beyond
the maximum allowable length recorded in step 3.

Outer Shielding has been removed for clarity.
IMPORTANT: Two small chains are supplied with
the driveline. These chains must be attached to
outer and inner driveline yoke shields and to the
cutter and tractor to keep driveline shields from
rotating.
