The packer tire bulges slightly to provide uniform packing over the seed and
fertilizer furrows. This leaves the seed 0.75 in (19 mm) below the curved path left
by the packer wheel. The seed is placed in an ideal environment: moisture will be
channeled into the path of the packer tire; fertilizer is placed in the optimum
position for seed growth; and the seed knives leave a dark strip, which warms
more quickly than the surrounding residue covered soil.
