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.
WARNING

NOTE
Due to the many variations in trac-
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:

If driveline is correct length, omit the fol-
lowing steps “G” through “J” and proceed
to step “K”.
