Quick Pin NOTE: Seed and fertilizer depth are always measured down from
the packed surface of the furrow.
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
fertilizer 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
moisture.
Hydraulic pressure to the main arm assemblies is controlled and adjusted from the
tractor.
You are responsible to check your seed depth across your seeder every
time you adjust your seeding depth.
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 0.75in (19 mm) below the packed surface of the soil.
Fertilizer is placed approximately 0.75in (19 mm) below and 1.50 in ( 38 mm) to
the side of the seed.
