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:

SECTION II

PREPARATION FOR USE

2-1 ATTACHING TO TRACTOR

NEVER  STAND  BETWEEN  TRACTOR  AND 
CUTTER WHILE TRACTOR IS BEING BACKED 
TO HITCH.

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.

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)

WARNING

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.

higher  than  rear  for  extra  shredding.    Shut  down
tractor.  Securely block cutter in position.  For further
explanation of cutter adjustment, see paragraph 3-2.
