Zusammenfassung:A planter row unit (10) includes a row unit frame (20), a furrow opening assembly (30), a depth adjustment mechanism (60) and a downforce load sensor with a load sensing connector rod (200) coupled with a depth selector (62) of the planter row unit. The load sensing connector rod is disposed to receive a load applied by a stop member (120) supported on the row unit frame, the stop member being in abutment with an abutment member (48-1, 48-2) of a gauge wheel arm (42-1, 42-2) of the furrow opening assembly. The load sensing connector rod generating load signals corresponding to a downforce applied to the soil by the gauge wheels (34-1, 34-2) of the furrow opening system of the planter row unit.
