Materials Clean-Out

Main Box and Dual Box Clean-Out

Refer to Figure 37, 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.

Native Grass Box Clean-Out

If a suitable vacuum is available, open the Native Grass

box lid, and vacuum out remaining seed.

If too much seed remains for the vacuum, or no vacuum

is available:

1. Raise and lock up the drill. Place a tarp under the

Native Grass seed tubes.

2. Set the Native Grass (right gearbox) Drive Type to 4.

Optionally install the smallest ﬁnal Driven sprocket.

3. Install the calibration crank, and turn the drive

system until no seed ﬂows from Native Grass tubes.

4. Vacuum out any residual material from above.

Equipment Damage Risk:

Water wash-out is not recommended for the Native Grass box,

particularly if seed lubricants have been used. Water may

cause build-up of solidiﬁed residue. Filler material used in

native grass mixes can also present problems.
