PREPARATION FOR USE

2-1 ATTACHING TO TRACTOR

WARNING

NEVER STAND BETWEEN TRACTOR AND 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. Arrange hitch pins, flexible link and bushings on heavy duty hitches as shown in Figures 2-1 and

2-2 depending on your tractor and hitch type. Regular standard duty hitches need no adjustment.

B.Attach cutter to tractor 3-point hitch per tractor operator’s manual. Do not attach driveline at this time.

C.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.

NOTE

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		Securely
cutter in position of shortest distance.
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.
