ABSTRACT:
A control system for an acreage counter, controllable by an electrical logic condition, includes: a flip-flop having enable logic condition output upon being set, and an inhibit logic output upon being reset; an enable counter and an inhibit counter connected respectively to the set and reset inputs of the flip-flop; an enable clock and an inhibit clock connected respectively to the enable and inhibit counters; and sensors or switches connected to the respective counters and cooperating respectively with an operating lever or operating switches of an agricultural implement to actuate the associated counters upon change in the status of the operating controls. The clocks and counters function to delay setting or resetting of the flip-flop for a selected time so that minor adjustments may be made to the working position of the implement without falsely initiating or interrupting the acreage counter.
