Abstract

A planter row unit is positioned so a gauge wheel and an opener are in a known position relative to one another. A planting depth actuator that travels along an extent of travel to change a relationship between the gauge wheel and opener is positioned at one end of its extent of travel, out of engagement with a gauge wheel arm and is then moved to an engagement position where it engages the gauge wheel arm. The location of the engagement position is identified as a calibration point.
