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
Thepointrowvalve blockwill be plumbed directly after 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. Whenpower is supplied
to a solenoid, oilis routed to theTank port on the reducing valve and the openers will raise.
The point row valve block will be bolted toa 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.
TheCounterbalance valvewith thepoint row kit is
thicker than the reducing valveit is plumbed to.
Because of this, the pressure LH reducing valve
willneedto be shimmed outwithwashersto make
room for the new valve.
Center and Wings Vs.LH andRH wings.The drill
is originally plumbed so the two cylinders at the
center of the drillshared a reducing valve and the
outercylinderssharedanother. Withthepointrow
option, the drill plumbing is altered so the LH reducing valve controls the LH wing and the RH
valve controls the RH wing.
A solenoid valve will be installed in the bypass
valveblocklocated on the drill. The solenoid valve
blocksflow throughthe bypassvalve everytime a
point row switch is activated. This stops the bypass oil and lets the tractor pressure increase
enough to raise the openers off the ground when
a section is shut off.
OncethePointRowkit has been installed,thedrill
needs to be raised and loweredso the complete
installation can be checked AND the new Counterbalance valve can be checkedand adjusted if
needed. Refer to "Adjusting the valve" at the end
of these instructions.

Assembly Instructions
Hook the drill to a tractor. Move the opener lock
handles to "Field", unfold the drill and lower the
openers to the ground. Place the remote lever in
float position to relieve any residual hydraulic
pressure. Clean the area around the pressure reducing valves bywashing or using compressed
air.
Disassembly
Refer to Figure 1
1. Removehoses(1),(2),(3),(4),(5) and (6) from
