WARNING!
Damaged drivelines can cause serious injury or death.
Either a tractor with 540 rpm or 1000 rpm PTO (Power
Take-Off) speed is required. The RCR cutters are
designed for a PTO speed of 540 rpm and the RCRM
cutters are designed for 1000 rpm.

Checking Driveline Minimum Length
Refer to Figure 1-14 on page 17:
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
IMPORTANT: Do not attempt to operate a 540 RPM
driveline cutter with a 1,000 RPM PTO tractor and
do not operate a 1000 RPM driveline cutter with a
540 RPM PTO tractor. Many tractors provide both
540 and 1,000 RPM PTO speeds. Check your
tractor’s manual to determine its capabilities.
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. See Figure 1-15 below.

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.
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. Slide inner yoke of driveline over the gearbox
shaft and secure with locking collar.
b. Slide outeryokeof driveline overthe tractor's PTO
shaft and secure with locking collar.
c. Skip to step 5 if driveline fits between tractor and
Rotary Cutter.
Refer to Figure 1-16:
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 1-16.

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
determineif they aretoo long. The inner andouter
shields oneach section shouldend approximately
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.
