on the meter operation fan. Then from the tee on the
meter pressure fan to the tractor.

Air System - Row Hoppers
Performance Risk
The balance baffles are factory set and are not
to be adjusted. Any adjustment made will be
very difficult to reset to factory setting.
A hydraulic fan supplies air for seed meter operation.
Fan rpm is adjusted using the tractor remote
hydraulic flow control.
Air from the hydraulic fan (1) flows to the planter
frame. The air then flows out the air outlets to
pressurization tubes (2). The tubes route air to each
row unit.
The main baffle (3) on the fan outlet adjusts air flow.
See page 36 for baffle adjustment.
The baffles (4) balance the air for the wings and
center sections. Do not adjust these baffles.
Seed is delivered from the hopper (5) by gravity to
the seed meter.
Seed enters the meter at the seed inlet and forms a
seed pool (6) at the base of the meter. The gate
handle controls the seed inlet gate (7) and the size of
the seed pool. The inlet gate also minimizes air loss
back up the seed inlet tube. See page 40 for gate
adjustments.
The meter disk is driven by a chain drive connected
to the drive shaft or IRC.
At the meter, pressurized air exits the meter through
the seed cells (8) of the disk, and holds seed in the
cells until released above the seed tube (9). Excess
seed at a cell is picked off by the tufted brush (10).
The strip (11) and drop (12) brushes block meter
pressure air. Seeds passing the drop brush are free
to fall into the seed tube.
The seed tube sensor (13) detects seeds passing
and reports to the console. Medium size and large
seeds are counted individually. For smaller seeds,
the seed sensor acts as a blockage monitor.
