UNLOADING & ASSEMBLY
INSTALL TONGUE
IMPORTANT: If there is more than one machine
to be assembled, and they are different sizes (12
ft., 14 ft., 16 ft.) and/or different PTO speeds (540
or 1000), be sure the proper tongue is matched to
each unit. Tongues are identified on a plastic tag
tied to the hose support near the front end. Should
this tag be missing, tongues can be identified by
length as follows:
HEADER SIZE TONGUE LENGTH *
12 ft. 17’ 7" (5360 mm)
14 ft. 19’ (5780 mm)
16 ft. 21’ 7 1/2 " (6590 mm)
* Tongue length is measured from center of pivot
hole at back end to center of hitch pin hole at
front end.
1. Ensure plastic bushings are installed in pivot
hole at back end of tongue. Remove the
shipping wire that secured the bushings.
NOTE: The two shorter bushings (A) install
from top of tongue, the longer one (F) from the
bottom.
2. Install jack in working position at front of
tongue.
3. Cut the banding that secures the hydraulic
cylinder to the tongue, allowing cylinder to
move away from frame as tongue is lowered.
WARNING: Keep hands clear when
lowering tongue.
4. Attach chain from lifting vehicle or hoist to
tongue as described on page 70. Lower tongue
(B) onto pivot pin. NOTE: Use the jack to
adjust the pitch of the tongue for proper
alignment when installing onto pivot pin.
5. Before tongue is lowered completely, position
retainer (C) on top of tongue, over pivot pin
bolts (D) and start 5/8 lock nuts (E). Clearance
to hydraulic lines will prevent installing this
retainer and nuts once the tongue is fully
lowered.
6. If tongue is not fully seated on pivot pin, use
nuts (E) to draw the tongue down completely.
Torque two 5/8 lock nuts (E) to 160 ft.lbs. (215
N
⋅
m).
7. Remove lifting brackets from tongue when
complete.
