These instructions explain how to install the Point
Row option. The Point Row option allows you to
raise and lower openers on each drill section
independently.

Definitions
Right-hand (RH) and left-hand (LH) as used in this
manual are determined by facing the direction the
machine will travel while in use unless otherwise
stated.
Overview of Installation
The point row valve block will be plumbed directly af-
ter the filter on the drill. Oil from the valve block is
directed to both the LH and RH wing reducing
valves all the time. With no power to a solenoid, oil
flows to the P port on the reducing valve, and the
openers are pushed down. When power is supplied
to a solenoid, oil is routed to the Tank port on the re-
ducing valve and the openers will raise.

The point row valve block will be bolted to a plate
on the drill just ahead of the base end of the fold
cylinders. Two bulk head hydraulic T fittings pass
through this plate from the original plumbing.
These fittings will be removed to make room for
the valve.
The Counterbalance valve (CBV) supplied with
the point row kit will hang under the LH pressure
reducing valve.
The Counterbalance valve with the point row kit is
thicker than the reducing valve it is plumbed to.
Because of this, the pressure LH reducing valve
will need to be shimmed out with washers to make
room for the new valve.
Center and Wings Vs. LH and RH wings. The drill
is originally plumbed so the two cylinders at the
center of the drill shared a reducing valve and the
outer cylinders shared another. With the point row
option, the drill plumbing is altered so the LH re-
ducing valve controls the LH wing and the RH
valve controls the RH wing.
A solenoid valve will be installed in the bypass
valve block located on the drill. The solenoid valve
blocks flow through the bypass valve every time a
point row switch is activated. This stops the by-
pass oil and lets the tractor pressure increase
enough to raise the openers off the ground when
a section is shut off.
Once the Point Row kit has been installed, the drill
needs to be raised and lowered so the complete
installation can be checked AND the new Coun-
terbalance valve can be checked and adjusted if
needed. Refer to "Adjusting the valve" at the end
of these instructions.
