Refer to Figure 70
The YP2425A Planter includes a sensing switch
that
signals the seed monitor and activates the hydraulic
meter drive, when the planter is lowered for planting.
Although factory-preset for typical planting conditions,
Great Plains recommends adjusting this switch for your
exact field conditions and planting depth. Check the
switch seasonally thereafter, or when planting conditions
change. Also perform this adjustment if the switch is
replaced or dislodged.
The switch is located on the outside of the forward end of
the right link arm at the center section tool bar.
Note: Switch is in neutral position when planting. Switch
is “activated” when raised.
Refer to Figure 71
