CUTTER WHILE TRACTOR IS BEING BACKED
TO HITCH.
WARNING
ADDITIONAL TRACTOR FRONT BALLAST
MAY BE NEEDED FOR STABLE OPERATION
AND TRANSPORT OF THE 3-POINT HITCH
MOUNTED CUTTER. SEE TRACTOR OPERA-
TOR'S MANUAL FOR RECOMMENDED
WEIGHTS.
WARNING
DO NOT USE PTO SHAFT ADAPTERS TO
CHANGE SIZE OF TRACTOR PTO SHAFT.
THE CORRECT DRIVELINE MUST BE USED
TO MATCH TRACTOR PTO SHAFT.
A. Attach cutter to tractor 3-point hitch per tractor
operator's manual. Do not attach driveline at this
time.
IMPORTANT
Tractor top link pin securing 3-point hitch top link to
cutter must conform to dimension shown in Figure 2-
1 to avoid interference with A-frame.
B. Raise 3-point hitch until front of cutter is approxi-
mately 1-2 inches (25-51mm) lower than rear for
standard cut or until front of cutter is 1 inch (35mm)
higher than rear for extra shredding. Shut down
tractor. Securely block cutter in position. For further
explanation of cutter adjustment, see paragraph 3-2.

Due to the many variations in tractor / imple-
ment hitch points and corresponding differ-
ences in distances between tractor PTO
shafts and implement input shafts, drivelines
may need to be shortened as described in the
following steps:
D. Raise and lower cutter to determine position
with shortest distance between the tractor PTO shaft
and gearbox input shaft. Shut down tractor leaving
cutter in position of shortest distance. Securely
block cutter in position.
E. Pull driveline apart. Attach outer (female) sec-
tion to tractor PTO shaft. Pull on driveline section to
be sure that yoke locks into place.
F. Hold driveline sections parallel to each other to
determine if too long. Each section should end
approximately 3 inches (76mm) short of reaching
universal joint shield on opposite section. If too
long, measure 3 inches (76mm) back from universal
joint shield and mark on opposite section. (Figure 2-
3). Do this for both sections.
G. Raise and lower cutter to determine position
with greatest distance between PTO shaft and gear-
box input shaft. Shut down tractor leaving cutter in
position of greatest distance. Securely block cut-
ter in position.
