Marker Setup (Option)
If markers are not installed, install them now per the
instructions included with the markers.
Once installed, verify that they have been correctly bled
(See “Bleeding Markers” on page 147).
Set initial marker extension - the distance to the mark on
each side from the outside row unit on that side.
1. Move the hitched drill to a typical flat field.
2. Extend a marker on one side (see page 36). Pull
forward a few feet or a meter or so to leave a mark.
3. Measure from the centerline of the outside row unit
(whether that row unit is to be used or not) to the
mark, along a line parallel to the wing.
Refer to Figure 230 through Figure 235 on pages 176 and 178
4.
Check the measurement against the value
recommended by Great Plains.
Refer to Figure 18
If the marker extensions need adjustment:
5. Loosen the nuts securing the U-bolt at the
outer marker section.
6. Slide the inner tube in or out, and re-secure nuts.
See page 94 for further marker adjustments. Re-check
marker extension when changing disk angle, or when
inverting the disk, as both adjustments change the
position of the centerline of the mark.
Install Weight Brackets (Option)
If weight brackets were ordered, and were not
dealer-installed, install them now. Two kits (4 brackets)
are supported, accepting five standard
100 pound (45 kg) “suitcase” tractor weights each, for a
maximum additional weight of 2000 pounds (907 kg).
Each empty bracket kits adds 121 pounds (55 kg) to the
drill. Weights are not included with kits.
If only one weight kit is to be installed, use the “Outer”
position.
Once the brackets are installed, see “Frame Weight” on
page 93 for operating information.
