For limited down-flex drills, the row spacing does not
change at wing gaps. The marker extension is one
half the span (distance between end rows) plus a
gap of one row space.
For standard drills, with higher down-flex, marker
extension is the same, but row spacing at the wing
gap is 216 mm for all models. This increases the
swath by one or two percent, or increases the
swath-averaged row spacing of the drill.
The pass gap in the table below is set to the nominal
row spacing for all models. It shows the actual swath
for both wing types, and effective row spacing for
higher down-flex drills. For most accurate seed
monitoring, use the information below.
To change marker extension, on a lowered drill:
1. Fully extend a marker.
2. Pull forward approximately 2 m, to leave a mark
and a furrow.
3. Loosen the jam nuts (1) and set screw bolts (2)
securing the outer marker arm.
4. Slide the outer arm in or out until the disk is at the
desired extension distance.
5. Secure the set screws and jam nuts.
6. Fold the marker.
Marker Speed
There is one adjustment screw for unfolding speed
(1) and one for folding speed (2). You can identify
adjustment screws by markings stamped in the valve
body. The screw marked
Raise controls the folding
speed. The screw marked Lower controls unfolding
speed.
Turn the adjustment screws clockwise (S) to
decrease folding/unfolding speed and
counter-clockwise (F) to increase folding/unfolding
speed.
With the tractor idling at a normal operating speed,
adjust marker folding to a safe speed. Excessive
folding/unfolding speed can damage markers and
void the warranty.
After adjusting the folding speed, tighten the jam nuts
on the hex adjustment screws to hold the settings.
Marker Disk Adjustment
Adjustments for marks are as follow:
1. Loosen the nuts (1) securing the guard (2) and
bracket (3). Change the angle of mark by shifting
the bracket, which has slotted holes. Align the
guard with the disk edge. Tighten the nuts.
Check marker extension again.
2. For a larger change in mark angle, the bracket
has a choice of small slotted holes on one side.
Loosen both nuts. Remove the bolt on the
two-hole side. Insert the bolt in the alternate hole.
Align the guard with the disk edge. Tighten the
nuts. Check the marker extension.
