8. Load the hopper with seed. If using a hydraulic auger
with the auxiliary hydraulic kit, refer to the instruc-
tions following.
9. Open the slide gate.
10. Return the ladder and platform to the closed posi-
tion.
Flow Inconsistency and Stoppage Risk:
Talc lubricant is mandatory for all seeds, especially treated or
inoculated seed when using the precision meter. Do not use
talc lubricant when using the finger pickup meters. Use graph-
ite lubricant with finger pickup meters. Refer to “Seed Lubri-
cants” on page 71.
Using Auxiliary Hydraulic Circuit
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.
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. Shutoff cab circuit, then auger. Return
Aux valve control handle to “Marker” position.
