12. Using the tractor hydraulics, raise or lower the main-
frame to set the tool-bar height with the box-mount
height. Rotate the tool-bar pivot hub until it aligns with
the box-mount bolts. Back the main frame up until the
tool-bar pivot has nested in the box mount. Replace
the lock washers and nuts on the box-mount bolts and
tighten.
13. Repeat steps 11. and 12. for the other box.
14. Attach the rod end of the tool-bar cylinders (7) to the
floating link plates (8).
15. Install wing transport carriers (9 and 10) on the
tongue. Position the carriers so that center of the front
bolt (11) is 103 in. from the center of the hitch mount-
ing bolts (12). Leave the carri-
er bolts loose for repositioning
when the drill is first folded.
IMPORTANT: There
are left and right trans-
port carriers. They must
be installed correctly.
When standing to one
side of the drill, the top
of the carrier tube
should lean toward the
rear of the drill.
16. Route the pull cables (13) from
their shipped position and pin
the adjusting-end clevis to the
drill using hardware supplied
(14).
17. Tighten all bolts as specified in
the Torque Values Chart on
the “Appendix” on page 11.
Plumb Field-Lift Hydraulics
1. Untie and uncoil the field-lift hydraulic hoses from the
drill tool bars. Remove the double-female, 3/4-in. O-
ring union from the circuit. Route the hoses to the wing
gauge-wheel cylinders through the clamps on the box
frame and holes in the box panels behind the frame
tube.
2. Complete the plumbing by following the schematic in
Figure 1-2. The base- and rod-end hoses must be
identified and plumbed correctly.
3. Allow 48 in. of hose between the hose clamp on the
tool bar (Figure 1-1, 15) and the hose clamp on the
box (Figure 1-1, 16).
