Driveline Installation
If the Rotary Cutter is to be used on more than one
tractor, an additional driveline may be required especially
if a quick hitch is used.
!
CAUTION
Do not use a PTO adaptor. A PTO adapter will increase strain
on the tractor’s PTO shaft resulting in possible damage the
shaft and driveline.
!
CAUTION
Tractor PTO shield and all Rotary Cutter guards must be in
place at all times during operation!
!
CAUTION
Always engage parking brake, shut off tractor and remove key
before dismounting from tractor.
!
WARNING
Damaged drivelines can cause serious injury or death.
Maximum PTO Driveline Movement During Operation
Figure 1-10
IMPORTANT: Some tractors are equipped with
multispeed PTO ranges. Be certain your tractor ‘s
PTO is set for 540 rpm.
IMPORTANT: Avoid premature driveline
breakdown. A driveline that is operating must not
exceed an angle of 25 degrees up or down while
operating the 3-point lift. See Figure 1-10 below.

Driveline Minimum Length
Refer to Figure 1-11 on page 14:
1. Obtain the shortest distance possible between
tractor PTO shaft and gearbox shaft by starting the
tractor and slowly engaging 3-point lift to move the
lower arms up or down until the gearbox shaft is
aligned and level with the tractor's PTO shaft.
Securely block cutter deck in this position.
2. Place tractor gear selector in park, shut tractor
engine off, set park brake and remove switch key.
3. Attach driveline to cutter and tractor as follows:
a. Remove gearbox shaft cover (#8). (See Figure 1-
9 on page 12.)
b. Slide inner yoke of driveline over the gearbox
shaft and secure with locking collar.
c. Slide outer yoke of driveline over the tractor's PTO
shaft and secure with locking collar.
d. Skip to step 5 on page 14 if driveline fits between
tractor and Rotary Cutter.
4. The driveline will require shortening if it is too long to
fit between the 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 1-11.
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.
IMPORTANT: 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.
IMPORTANT: It is necessary to align and level the
tractor’s PTO shaft with the gearbox shaft when
checking driveline minimum length. Too long a
driveline can damage tractor, gearbox and driveline.
