4.8.8 Knife Lateral Separation
Confirm knife lateral separation, “Z” 1.5 in (38 mm), Figure 14, 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 15. The
formed rubber drop tube is attached to the knife
by sliding tab, #2 Figure 15 into the slot on the
opener shank.
As the formed rubber drop tube wears, it can be
trimmed and repositioned. Refer to Figure 16 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.
