Double Selector Valves (Option)
Refer to Figure 38
Drills equipped with markers use a double selector valve
to combine the transport fold hydraulic circuit with the
marker hydraulic circuit.
Tractors with only two sets of remote hydraulic outlets
must use a second double selector valve, (see page 95).
This combines the transport lift hydraulic circuit and
opener lift hydraulic circuit.
To operate the double selector valves, turn handle on top
of valve toward hydraulic hoses of the circuit which you
wish to operate.
Point Row Operation (Option)
Refer to Figure 39
The point-row option (page 93) allows you to raise and
lower openers on one drill section independent of the
others. To raise and lower openers on all sections
together, flip power switch
so master-lift-control
light is on. Raise or lower all openers by moving the
switch under the light.
To raise and lower openers on one section independent
of the others, flip power switch so section-control-light
is lit. Raise and lower openers on a section by moving
the switches under the light.
Note: Turn power switch for point row off when tractor is
off.
Shaft Monitor Operation (Option)
Refer to Figure 40
The optional shaft monitor (page 94) sounds an alarm if
any seed shaft stops for more than 20 seconds.
To operate shaft monitor, turn system on by activating
on-off switch
on monitor head. If seed-cup shaft is
turning, all section lights will be on and the alarm will not
sound.
If any seed-cup shaft stops for 20 seconds, an alarm will
sound and a light on the monitor will flash designating
the failed shaft.
The 20-second delay is to prevent nuisance alarms when
turning at the end of the field. If a failure does occur and
an alarm sounds, remember that you have traveled for
20 seconds without planting.
