Agricultural implement skew detection and correction
First Claim
1. An apparatus for detecting skewing in an agricultural implement where the implement includes a ground engaging tool mounted on a front portion thereof and operative to create a furrow in a ground surface, the apparatus comprising:
- a furrow sensor mounted on a rear portion of the implement rearward of the ground engaging tool such that when the implement is travelling in a desired operating orientation the furrow sensor is in an aligned position where the furrow sensor is aligned in an operating travel direction of the implement with the front furrow opener;
wherein the furrow sensor is operative to detect the furrow and send a skew correction signal when the furrow sensor detects that the rear portion of the implement is laterally displaced from the furrow compared to the aligned position.

Abstract
A system for correcting skewing in an agricultural implement where the implement includes a plurality of ground engaging tools laterally spaced across a width of the implement and operative to selectively engage the ground to perform a desired operation on a field surface has a skew detecting device operative to sense when the implement is travelling in a skewed orientation and send a correction signal indicating the skewed orientation to a correction mechanism. A drag force is exerted on the ground engaging tools by engagement with the ground when performing the desired operation on the field surface, and the correction mechanism is operative to change the drag forces exerted on at least some ground engaging tools on one side of the implement to correct the skewed orientation.
