Electric Clutch Operation
The YP40 planter has three clutches in the seed meter
drive system. A clutch enables or disables groups of row
units. The information in the table below is normally
preset at the factory for your planter configuration.
The switches Left / Center / Right correspond to
the left wing row units, center section row units and right
wing row units respectively.
The Master switch controls all row units, regardless of
drive type. For all switches, “OFF” (down) removes power
from the clutch, disengaging that set of row units. When
any switch (plus Master) is ON, the LED for that switch
illuminates steadily.
Y-Tubes
Refer to Figure 36
Y-tube gates can be shut off, for example:
• to plant 30 in. corn on a 15 in. planter, or
• to feed only one row for single-row planting on a
twin-row machine.
In the photograph, both meter tubes are open.
You can also shut off the Y-tube gates to clean out the air
system and meters. See “Cleaning Out Air System” on
page 102.
