Materials Clean-Out
Main Seed Box Clean-Out
Refer to Figure 67, 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
in (22mm) open-end wrench, while
another inspects the flutes from the open seed boxes.
Fertilizer Box Clean-Out
After applying fertilizer, clean drill boxes as soon as
possible. Fertilizers often contain chemicals corrosive to
metal.
Refer to Figure 68
With a small scoop or can, remove as much fertilizer as
possible from drill boxes.
Clean-out releases material across the entire length of a
section box. Have collection equipment prepared.
Release all clean-out latches on a drill section, and open
clean-out door. Leave door open until after washout.
Refer to Figure 69
Wash inside of drill boxes with water under high
pressure. To aid clean out, lift vinyl dew shield and spray
into fertilizer trays (with clean-out door open).
Let drill boxes dry before closing clean-out doors.
