Materials Clean-Out
Main Box Seed Meter Clean-Out
Refer to Figure 102, which depicts the seed cup door
handle
in a normal operating position .
1. Set the Seed Rate Handle to zero (0) for the section
of the drill to be cleaned out. This moves the seed
cup sprockets out of the seed path.
2. Position a tarp or bucket under each row or set of
rows to be cleaned out.
3. At the seed cup for that row, pull the door handle
out of the operating detent range, and swing it down
to position
.
4. Open the main seed box and use a small brush to
sweep seed toward seed cups set to clean-out. If
seed does not flow freely, inspect seed cup, hose
and seed tubes for obstructions.
5. Wash out the seed box with high pressure water.
It is not necessary to operate the seed meter drive shaft
for clean-out. With the Seed Rate set to zero, nothing
moves inside the seed cups; however, an inspection of
the flutes for excess wear and damage does require
shaft rotation.
Set the Seed Rate Handles to 100. With openers raised,
the seed meter jackshaft can be slowly turned by one
person with a
7 ⁄
8
inch (22 mm) open-end wrench, while
another inspects the flutes from the open seed boxes.
