SECTION II

PREPARATION FOR USE

B.  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.

C.  Pull  driveline  apart.  Attach  outer  (female)  sec-

tion to tractor PTO shaft. Pull on driveline section to
be sure yoke locks into place.

D. 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  opposite  section.  (Figure  2-1).  Do
this for both sections.

E.  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.  SECURELYBLOCK
CUTTER IN POSITION.

F. Hold down driveline sections parallel to each 

other  and  check  for  minimum  6  inches  (152mm)
overlap. (Figure 2-2) If driveline has been marked for
cutting,  overlap  will  be  the  distance  between  two
marks.  If  driveline  has  less  than  minimum  overlap,
DO NOT USE. Contact authorized Bush Hog dealer.

tor/implement  hitch  points  and  corre-
sponding differences in distances between
tractor  PTO  shafts  and  implement    input
shafts,  drivelines  may  need  to  be  short-
ened as described in the following steps:

NOTE

If  driveline  is  correct  length,  omit  the  fol-
