Agricultural implement skew detection and correction
First Claim
1. A system for correcting skewing in an agricultural implement where the implement includes a plurality of ground engaging tools laterally spaced substantially evenly across a width of the implement and operative to selectively engage the ground to perform a desired operation on a field surface, the system comprising:
- 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;
wherein the correction mechanism is operative to vary a depth of ground penetration of at least some ground engaging tools on one side of the implement to to correct the skewed orientation.

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.

8. An agricultural seeding implement apparatus comprising:
-
an agricultural seeding implement comprising a plurality of furrow opener assemblies laterally spaced substantially evenly across a width of the implement and operative to selectively engage the ground such that the furrow opener assemblies form furrows in the ground, and a distribution system operative to deposit an agricultural product into each furrow; 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; a correction mechanism operative to receive the correction signal and operative to vary a depth of ground penetration of at least some furrow opener assemblies on at least one side of the implement to correct the skewed orientation. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method of correcting skewing in an agricultural implement where the implement includes a plurality of ground engaging tools laterally spaced substantially evenly across a width of the implement, and where the ground engaging tools are operative to selectively engage the ground to perform a desired operation on a field surface, the method comprising:
-
engaging the ground engaging tools in the ground to perform the desired operation; detecting when the implement is travelling in a skewed orientation and sending a correction signal indicating the skewed orientation; receiving the correction signal and in response, varying a depth of ground penetration of at least some ground engaging tools on one side of the implement to correct the skewed orientation. - View Dependent Claims (15, 16, 17, 18, 19, 20)
