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.
