PREPARATION AND SETUP
DR12x2 Row Hopper Planter OM-EN 4-11
Internal Toolbar Vacuum
Circuitry
An internal toolbar vacuum circuit has been designed into
the DR12x2 Row Hopper Planter. The vacuum air for the
seed meters is routed from each row unit (1) to the
internal space of the toolbar, which is then connected to a
vacuum fan (3) via a flex hose connected to another
internal toolbar vacuum inlet (4).

At the ends of each toolbar section (wings and center) on
the bottom face, there are rubber plugs fitted on slots to
seal the toolbar. The slots are machined out of the
toolbar to serve as a means of access to the inner space
of the toolbar if necessary.
Hitch Pin Position
The DR12x2 Row Hopper Planter can be configured for
single row or twin row planter operation. See the tractor
operator’s manual for properly setting the row units for
each operation. Attach the tractor to the appropriate hitch
pin location for each setting. See “Implement-to-Tractor
Connection” on page 4-4.
