Lift Selector Valve Operation
Tractors with only two remote circuits need an optional
selector valve, which shares a single tractor circuit
between transport lift and opener lift. Two Outlet Tractor
Hydraulic Kit Great Plains Part number 194-122A. This
combines the transport lift hydraulic circuit and opener lift
hydraulic circuit.
If no markers are installed, the lift selector valve is
mounted on the standard tongue valve plate near the
hitch. If markers are also installed, the lift selector valve
mounts above the marker valve on an extension plate.
Refer to Figure 40, which depicts the optional lift selector
valve on a drill without markers.
To operate, move handle from forward transport lift

lift circuit or opener subframe circuit. Use the lift
locks.
