Patent

CA 2240568

The invention provides a guidance system for guiding a no-till seeder such that the furrow openers of the seeder travel along the field between the standing stubble rows from the previous crop, thereby leaving the stubble rows standing and reducing plugging of the seeder with crop residue. The guidance system comprises sensing means to sense the standing stubble rows from the previous crop and to send a steering signal in response to changes in the relative position of the seeder to the standing stubble rows; and adjusting means to adjust the travel path of the seeder in response to the steering signals. The sensing means is a wedge-shaped pan adapted to ride along the ground between two standing stubble rows from the previous crop. Lateral movement of the pan sends a steering signal to the adjusting means, conveniently a hydraulic cylinder, via a solenoid valve which cylinder moves the seeder to the left or right relative to the towing vehicle. A furrow sensor is also provided.
