| 摘要 |
The invention provides a method of reducing plugging of a no-till seeder with crop residue by guiding the furrow openers of the seeder between the standing stubble rows of the previous crop. A guidance system is provided comprising 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 can sense the location of the standing stubble rows by contact therewith or by sensing the furrow from which the standing stubble rows extend. The position of the seeder relative to the towing vehicle is adjusted in response to steering signals sent by the sensing means.
