Assemble Center Opener Weldment
(see Parts Manual section: Opener Mount to Frame)
Refer to Figure 70 and Figure 71
Orientate mount so shims on mount are up and forward on
center section. Not doing so will cause interference with the
cylinders.
Center Section Opener Mounting:
1. Install upper and lower parallel arms to frame with
the hydraulic cylinder running behind the upper par-
rallel arm and through the lower parallel arm (leave
the bolts for the lower parallel arm assembly loose
and leave shims out until toolbar is completely
installed).
2. Supporting both ends of the toolbar, slide it under the
frame into position.
3. Install pivot tubes in lower parallel arms attaching the
toolbar.
4. Install pivot tubes in the upper parallel arms in the
same manor.
5. Install shims as needed to the lower parallel arms
and tighten all bolts on the parallel arms.
6. Extend and hook up cylinders to the toolbar.
You will need to use the hydraulics to raise the toolbar to
hook up and adjust the down pressure spring for the con-
tact drive.
