It takes about a minute to initially fill the
seed meters.
Seed Meter Air Flow
Dealer Servicing and Repair Risk
Do not adjust balance baffles.The balance
baffles are factory set and are not to be
adjusted. Any adjustment made will be very
difficult to reset to factory setting.
Material Loss Risk
Running a seed disk with no seed, or with an
open empty inlet, unbalances the air system.
Doing either at a sensor row causes the gauge
to report incorrectly.
Air from the seed meter operation fan (5) flows to the
planter frame. The air then flows out the air outlets to
pressurization tubes (6). The tubes route air to each
row unit.
The main baffle (7) on the fan outlet adjusts air flow.
See page 36 for adjustment.
The baffles (8) at the seed meter air splitter balance
the air for the wings and center sections. Do not
adjust these baffles.
Seed enters the meter at the seed inlet (9) and forms
a seed pool (10) at the base of the meter. The gate
handle controls the seed inlet gate (11) and the size
of the seed pool. The inlet gate also minimizes air
loss back up the seed inlet tube. See page 40 for
inlet gate adjustments.
The meter disk is driven by a chain drive connected
to the drive shaft, or the IRC.
At the meter, pressurized air exits the meter through
the seed cells (12) of the disk, and holds seed in the
cells until released above the seed tube (13). Excess
seed at a cell is picked off by the tufted brush (14).
The strip (15) and drop (16) brushes block meter
pressure air. Seeds passing the drop brush are free
to fall into the seed tube.
The seed tube sensor (17) detects passing seeds
and reports to the console. Medium size and large
seeds are counted individually. For smaller seeds,
the seed sensor acts as a blockage indicator.
