2. Locate 1 3/16" holes on end of rear brace bars (#4)
and attach that end to rear strap lugs with
5/8"-11 x 1 3/4" GR5 bolts (#6), bushings (#3), flat
washers (#10) and hex flange lock nuts (#9). Tighten
lock nuts (#9) to the correct torque.
3. Secure shields (#15 & #16) and front brace bars (#5)
to end of floating top hitch (#13) that does not have
ears (#14) with bolt (#7) and locknut (#8). Draw lock
nuts (#8) up snug and then back off 1/4 turn.
4. Insert spacer tube (#1) through top holes in brace
bars (#5). Secure spacer tube with clevis pin (#12)
and hairpin cotter (#11).
5. Rotate front brace bars/floating top hitch (#5 & #13)
up and rotate left rear brace (#4) up until holes in rear
braces (#4) align with hole in floating top hitch (#13).
6. Insert 3/4"-10 x 4 1/2" GR5 bolt (#7) into the left rear
brace (#4), floating top hitch (#13), and right rear
brace (#4).
7.
Secure bolt with hex flange locknut (#8). Draw
locknut (#8) up snug and then back off 1/4 turn.
IMPORTANT:
See Detail A in Figure 1-1. Floating
top hitch (#13) must be installed with ears (#14)
above rear brace bars (#4).
NOTE:
After assembly of hitch, push on top of
A-frame assembly (#5). It should rotate backwards
and floating top link (#13) should rotate upwards. If
they are too stiff to rotate, loosen nuts (#8) until
floating top link (#13) rotates freely.

WARNING
!
To avoid serious injury or death:
Lightweight tractors with rear attached implements may need
weights added to the front to maintain steering control.
Consult your tractor Operator’s Manual to determine proper
weight requirements and maximum weight limitations.
Torque Requirements
Refer to
“Torque Values Chart”
determine correct torque values for common bolts. See
at bottom of chart for
exceptions to standard torque values.
Hitch Installation
1.
Assemble hitch braces (#5) to hitch plates using
5/8"-11 X 1 3/4" bolts (#6), bushings (#2), flat
washers (#10), and hex flange lock nuts (#9). Tighten
lock nuts (#9) to the correct torque.
