The seed and fertilizer knives are mounted at a fixed distance apart on the
opener arm assembly. The knives are also offset laterally to place seed and fer-
tilizer in adjacent, yet separate, furrows. The packer/gauge wheel packs the soil
around the complete disturbed areas of the furrows to ensure optimum seed/
soil contact and fertilizer placement as well as maintaining available soil mois-
ture.
Hydraulic pressure to the main arm assemblies is controlled and adjusted from
the tractor.
ATTENTION! It is the responsibility of the operator to check the
seed depth across the toolbar at every field.
3.6.2 Seed Depth
Placing the seed at the proper depth and keeping the depth setting consistent
are critical to achieving optimum germination. The packer wheels are factory set
to place seed at a depth of ¾ in. (19mm) below the packed surface of the soil.
Fertilizer is placed approximately ¾ in. (19mm) below and 1-½ in. (38mm) to
the side of the seed.
To adjust seed depth:
1. Remove retaining pin from the
quick pin.
2. Remove quick pin from opener
shank.
3. Rotate the packer arm gear using a
¾” wrench, and align the correspond-
ing pin hole with the desired depth
setting (marked on the decal).
4. Replace the quick pin and the
retaining pin.

ensure proper seed depth is
maintained.
