Shaft Monitor Operation
To operate shaft monitor, turn system on by activating on-
off switch on monitor head. If seed-cup shaft is turning,
both of the lights will be on and the alarm will not sound.
If either seed-cup shaft stops for 30 seconds, an alarm will
sound and a light on the monitor will flash designating the
failed shaft.
The 30-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 you have traveled for 30 sec-
onds without planting.

Marker Operation
Optional markers are equipped with a double-selector
valve to combine the transport-fold circuit with the marker
circuit.
After drill is unfolded for field operation, shift double-selec-
tor valve to marker circuit as shown in Figure 2-18. Before
operating markers, make sure they are properly bled as
described in Bleeding the Hydraulics, “Drill Preparation
and Setup,” page 11.

Shifting the Double Selector Valve
To operate a single marker, activate tractor remote hydrau-
lic lever to move marker in desired direction.
Single markers are equipped with a needle valve to control
marker folding speed. Excessive folding speed can dam-
age markers, so adjust needle valve to a safe operating
speed as described under Marker Adjustments, “Adjust-
ments,” page 21.
Dual markers are equipped with a sequence valve to con-
trol lift sequence. Starting with both markers up, the se-
quence is:
1. Activate hydraulic lever; right marker lowers while left
marker stays up.
2. Reverse hydraulic lever; right marker raises while left
marker stays up.
3. Activate hydraulic lever; left marker lowers while right
marker stays up.
4. Reverse hydraulic lever; left marker raises while right
marker stays up.
5. Pattern repeats.
Folding speed of dual markers is adjusted with adjustment
screws on sequence-valve body. Excessive folding speed
can damage markers, so adjust markers to a safe folding
speed as described under Marker Adjustments, “Adjust-
ments,” page 21.
