Using Auxiliary Hydraulic Circuit
!
WARNING
Never operate the selector valve with the marker hydraulic cir-
cuit active. Unexpected marker operations may result, with risk
of serious injury or death. Operate the valve only with the
marker circuit in Neutral or Float, or with hydraulics disabled.
The optional auxiliary hydraulic kit includes a manual
valve that diverts the marker hydraulic circuit to a pair of
quick-connect ports at the back of the seed cart.
1. Extend or fold any marker that is raised. Return the
cab control for that circuit to “off”.
2. Close any shut-off valve on your auger, and connect
the auger to the auxiliary quick-connect ports at the
back of the seed cart. If the auger hose is so
labelled, connect the Extend hose to the Extend Aux
port.
3. At the auxiliary selector valve (near marker
sequence valve on left wing), move the handle from
“Marker” to “Auxiliary”.
4. With no seed present, open the auger shutoff valve,
and operate the cab control to determine which set-
ting (“extend” or “retract”) turns the auger in the cor-
rect direction for seed lift.
5. Load seed.
6. Set marker circuit to Float. Shutoff any valve at
auger. Return Aux valve control handle to “Marker”
position. Disconnect auger.
