4.8.8 Knife Lateral Separation
Confirm knife lateral separation, “Z” 1.5 in (38 mm), Figure 15, especially after
replacing knives, to avoid seed damage when applying high rates of fertilizer.
NOTE
: As with any field adjustment
procedure, make only one change to a
variable, operate the implement for a short
distance and observe whether the change
made any difference and whether the
difference was positive or negative in
outcome.
4.9 SUPPLY AND DROP TUBES
4.9.1 Basic Configuration
Product is delivered to the knife through a
supply tube. The supply tube slides into a
formed rubber drop tube, #1 Figure 16. The
formed rubber drop tube is attached to the
knife by sliding tab, #2 Figure 16 into the slot
on the opener shank.
As the formed rubber drop tube wears, it can
be trimmed and repositioned. Refer to Figure
17 as a guide for repositioning drop tubes. All
drop tubes should be positioned so the tip of
the drop tube is 0.5 in (13 mm) below the
stainless steel clip. Always cut drop tube on
an angle to allow air to flow and escape.
