4.7.7 Cornering
4.8.1 Basic Conguration
4.7.6 Knife Lateral Separation
Ideally, the most effective seeding, fertilizer banding and soil packing occurs
when the implement is pulled in a straight line. Some eld conditions will not
allow all of the seeding to occur in a straight line. It is important to remember
that as the packer tire is following a curved path, it will tend to ride up on one
side of the furrow. Seed and fertilizer placement, as well as, packing perfor-
mance are all compromised.
Conrm knife lateral separation,
1 in. (25.4mm) between blades, espe-
cially after replacing knives, to avoid
seed damage when applying high rates
of fertilizer.
4.8 Supply & Drop Tubes
Product is delivered to the knife
through a supply tube. The supply
tube slides into a formed rubber drop
tube. The formed rubber drop tube
is attached to the knife by sliding tab
into the slot on the opener shank.
As the formed rubber drop tube
wears, it can be trimmed and repo-
sitioned. All drop tubes should be
positioned so the tip of the drop tube
is ½ in. (13mm) below the stainless
steel clip. Always cut drop tube on an
angle to allow air to ow and escape.
