ABSTRACT:
Disclosed is a method for controlling the above-ground "raise height" of a seed-planting row unit on an agricultural planter having a row marker, a marker switch and a positioning assembly such as a solenoid valve and hydraulic cylinder for raising and lowering the row unit. The method includes enabling the positioning assembly to raise the row unit and changing the marker switch from its first to its second position when the row unit reaches a predetermined height. The positioning assembly is thereby disabled. Such assembly is re-enabled after a brief time delay. The method is carried out using a unique implement control circuit connected to the marker switch and the positioning assembly.
