Auxiliary Hydraulics
Refer to Figure 39, Figure 40 and Figure 41
The Planter planter includes, as standard equipment, an
auxiliary hydraulic circuit, intended to power a seed
auger for loading bulk hoppers.
The Aux quick-disconnect ports are on the frame. This
circuit is shared with the markers (if installed).
Note: If markers are not installed, the Aux/Marker circuit
is always in Aux mode.
Operating Auxiliary Hydraulics
The planter needs to be unfolded for convenient access
to the manual hydraulic valve.
1. Fold any extended markers and set the tractor lever
for the marker/aux circuit to Neutral.
2. If no markers were unfolded, set the Clutch Folding
Module Marker/Fold switch
to “Marker”.
3. If the machine has markers, at the left wing tool bar,
move the lever on the manual valve
from
Marker (lever pointing forward) to Aux (lever
pointing back).
4. Connect the implement requiring hydraulic power.
5. Briefly Extend the tractor lever for the Marker circuit,
engage local valve/switch on implement, and confirm
proper implement operation (auger rotation in the
correct direction).
6. Set tractor circuit lever to Extend, and operate
implement with local controls.
7. When operation is complete, set tractor circuit to
Float or Neutral, and set wing valve
back to
Marker .
