Marker Setup
If markers were ordered with the drill, they were factory-
installed. If they were ordered separately, install them
now, per the instructions included with the markers.
1. Review “Marker Operation” on page 30.
2. Bleed the marker circuit. See “Bleeding Marker
Hydraulics” on page 73.
3. If you know that your conditions require a specific
marker disk orientation, change it now. See “Marker
Disk Adjustment” on page 54.
4. Adjust marker speed. See “Marker Speed” on
page 73.
5. Set the initial marker extension, below.
6. Fold the markers.
Initial Marker Extension
Marker Extension is the distance from the centerline of
the outboard row unit on each side to the centerline of
the mark left in the ground by the marker.
The 3S-4010HD and 3S-4010HDF is symmetrical, and
the values are the same on each side and independent
of next pass direction. On a dual-marker drill, set each
side.
To change marker extension:
If this is not the first adjustment to marker length.
1. Position drill on level ground and lower to planting
position.
2. Fully extend a marker.
3. If you plan to change the marker blade angle or
invert the blade, make that adjustment now (see
page 54).
4. Pull forward several feet to leave a mark.
5. Sighting along a line parallel to a tool bar, measure
the distance from the outside row unit centerline
(opener discs or furrow) to the mark. If the distance
matches the suggested value above, no marker
extension adjustment is needed.
6. Loosen U-bolt nuts securing outer marker tube .
7. Slide the tube in or out to change extension. Secure
the nuts.
8. Pull forward and re-measure new mark. Return to
step 6 if further adjustment is needed.
