Materials Clean-Out
Main Box Clean-Out
Refer to Figure 33, which depicts the seed cup door handle
in a normal operating position
.
1. Set the Seed Rate Handle to zero (0). 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. If a vacuum cleaner is available, use it to remove
residual material.
It is not necessary to operate the 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 Handle to 100 and disengage the
lock-out hub. With openers lowered to engage the clutch,
the seed meter jackshaft can be slowly turned with the
calibration crank, while another person inspects the
flutes from the open seed boxes.
Fertilizer Box Clean-Out
After applying fertilizer, clean the box as soon as
possible. Fertilizers often contain corrosive chemicals.
Refer to Figure 34
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
box. Have collection equipment prepared.
Release all clean-out latches on the drill, and open
clean-out door. Leave door open until after washout.
Refer to Figure 35
Wash inside of fertilizer box with high pressure water.
Let drill boxes dry before closing clean-out doors.
Small Seeds Box Clean-Out
1. Open box lid and scoop out as much seed as
possible.
2. To recover remaining seed, place a collection tarp
under the small seeds tubes at the openers.
3. Raise drill.
4. Set seed rate handle to 100.
5. Rotate calibration crank or end wheel until no seed
flows.
6. If a vacuum cleaner is available, remove any residual
seed from top of meters.
