11. Check the expected amount against the indicator
marks on the hopper. Indicator marks are at 10
inches (25.4 cm) increments.
12. Close an latch lid(s).
a. Swing lid over opening until the hook is centered
on the u-bolt latch.
b. Open the handle and engage the hook on the
latch.
c. Close the handle.
Auxiliary Hydraulics (Option)
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 the auger and
connect the auger to the auxiliary quick-connect
ports at the back of the seed cart.
3. At the auxiliary selector valve, move the handle
(1) from Fold to Auxiliary.
4. With no seed present, open the auger shutoff
valve, and operate the cab control to determine
which setting (Extend or Retract) turns the auger
in the correct direction for seed lift.
5. Load the seed.
6. Shut off the cab circuit, then the auger.
7. Return the auxiliary selector valve handle to
Fold.
8. Disconnect the auger hydraulic hoses at the
auxiliary ports.

Air System
The air system consists of two hydraulic fans. One
hydraulic fan supplies air for the seed delivery (1)
and the other hydraulic fan supplies air for the meter
operation (2).
Fan rpm is adjusted using the tractor remote
hydraulic flow control.
A sensor from the WSMT measures and reports the
air to the display in the cab.
In case of insufficient fan air or significant
seed delivery air leaks, seed flow may be
irregular or stop.
Some rows have lines to sample metering air
pressure which is measured in a sensor chamber.
The sensor reading is fed back to the WSMT for
pressure control. Air pressure is adjusted to preset
target in WSMT.
At the air box (3), air is mixed with seed from the
hopper and flows out the air box manifold ports into
seed hoses to the rows.
If seed delivery air flow is insufficient, the
indication will be low seed rate alarms. IF
fan speed and direction are as
recommended, check for air leaks in the
seed delivery system.
A screen (4) above each seed meter vents the
delivery air. The vent has two functions:
1. Releases delivery air while retaining the
delivered seed.
2. Controls bulk seed delivery.
When the meter inlet is filled and seed fills the tube
above the inlet, the screen becomes blocked by
seed, shutting of f the air flow to that meter. As the
meter uses seed, the screen is exposed and air
resumes flowing, carrying more seed to the meter.
It takes about a minute to initially fill the
seed meters.
