9.
Attach rear braces (#5) inside of tailwheel main
frame (#3) with 5/8"-11 x 1 3/4" GR5 bolts (#12) and
secure with hex flange locknuts (#14). Draw lock
nuts (#14) up snug and then back off 1/4 turn.
10. Manually rotate floating top hitch (#13) on bolt (#9B).
If it will not rotate, loosen hex flange locknut (#8B)
just enough to allow it to rotate.
11. Rotate A-frame/floating top hitch (#6 & #13) up and
rotate left rear brace (#5) up as follows:
a. If attaching cutter to a 3-point Cat. I hitch, align
holes (A) in rear braces (#5) with hole in floating
top hitch (#13).
b. If tractor is too small to lift cutter high enough for
transporting, align hole (B) in rear braces (#5) with
hole in floating top hitch (#13).
12. Insert 3/4"-10 x 4" GR5 bolt (#9A) into the left rear
brace (#5), floating top hitch (#13), and right rear
brace (#5).
13. Secure bolt (#9A) with hex flange locknut (#8A).
Draw locknut up snug and then back off 1/4 turn.
14. Install machine washer (#1A) on wheel spindle (#2).
15. Insert tailwheel spindle (#2) in tailwheel
A-frame (#3).
16. Install washer (#1B) on tailwheel spindle (#2).
17. Insert roll pin (#23) on spindle (#2) above
washer (#1B).
Install Driveline
IMPORTANT:
Floating top hitch (#13) must be able
to pivot on bolt (#9B). If it does not, hex flange
locknut (#8B) is too tight and should be loosened.
IMPORTANT:
See Detail A in Figure 1-2 on page 12:
Floating top hitch (#13) must be installed with
ears (#16) above rear brace bars (#5).
NOTE:
Bolts (#10) may need to be removed or the
rear of the cutter may need to be raised before
tailwheel spindle (#2) can be inserted into tailwheel
A-frame (#3).
NOTE:
After assembly of hitch and tailwheel, push
on top of A-frame assembly (#6). It should rotate
backward and floating top link (#13) should rotate
upward. If they are too stiff to rotate, loosen nuts
(#12 & #14) until they will rotate freely.
IMPORTANT:
The driveline must be lubricated
before putting it into service. Refer to
Driveline Installation
Figure 1-3
Refer to Figure 1-3:
1.
Unsnap both access covers (#4) by placing a
standard screwdriver in one of the slots at the back of
each cover to pry them open. Rotate covers down.
2.
Remove bolt (#2) from end of driveline (#5).
3.
Slide driveline (#5) onto gearbox input shaft until
holes in driveline yoke aligns with hole in gearbox
input shaft.
4.
Insert bolt (#2) through driveline yoke and gearbox
input shaft.
5.
Secure bolt with a new nylock nut (#3) or with a new
hex nut and jam nut (not shown).
•
If bolt (#3) is a shear bolt, draw nylock nut up snug.
If using a hex nut and jam nut, draw hex nut up
snug and tighten jam nut to the correct torque.
•
If driveline has a slip clutch, tighten nylock nut or
hex nut and jam nut to the correct torque.
6.
Skip to step #8 if installing a slip clutch driveline.
7.
If driveline (#5) has a shear bolt instead of a slip
clutch, install snap ring (#1) onto the gearbox input
shaft groove. Discard snap ring if driveline has a slip
clutch.
8.
Rotate access covers (#4) up and snap shut.
9.
Raise driveline (#5) up and rotate driveline hook (#6)
down.
10. Lower driveline (#5) until resting in driveline
hook (#6).

NOTE:
It may be necessary to use shallow sockets
or swivel sockets and socket extensions to secure
bolt (#2) while tightening nut (#3).
NOTE:
Snap ring (#1) is for extra security should
driveline shear bolt (#2) break. Do not use snap ring
with a slip clutch driveline.
