Y-Tubes
Y-tube gates can be shut off to feed only one row for
single-row planting on a twin-row machine. In the
photograph, the left meter tube is open and the right
closed.
You can also shut off the Y-tube gates to clean out the air
system and meters. See “
Airbox Operation
The function of the airbox is to mix seed with turbulent
air from the hydraulic fan, which then exits through a
manifold (not shown) to the seed tubes which serve the
row unit meters.
Before the first planting each season, or when using
new meters or meter wheels for the first time, or at the
start of each season, before filling with seed, add
1
/
3
cup (80 ml) graphite to bottom of airbox.
When starting empty you must blow seed out to the
meters for two to four minutes to fill meters.
The monitor has a level sensor below the hopper or seed
box to warn when seed box is empty. There are three to
four acres of seed in the system when the sensor first
indicates box empty, depending on seeding rate.
