SEED HAWK® 30 SERIES OPERATOR’S MANUAL 91
4.29 SUPPLY AND DROP TUBES
4.29.1 BASIC CONFIGURATION
Product is delivered to the knife through a supply tube. The supply
tube slides into a formed rubber drop tube, #1 FIGURE 4.125. The
formed rubber drop tube is attached to the knife by sliding tab, #2
FIGURE 4.125 into the slot on the opener shank.
As the formed rubber drop tube wears, it can be trimmed and
repositioned. 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.
The seed pipes are connected to the seed boots (A). The seed boots are clamped to the drill
coulters by stainless steel tine shields (B).
As the seed boots wear, they can be moved downwards. Cut off worn material with a hacksaw.
All the seed boots must be installed so that the distance between the seed boots and the
stainless steel tine shields is about 13 mm. SEE FIGURE 4.126.
