Abstract

The lock comprises a pivoted lever (8, 9) which forms part of the upper fixing point (5) of a tractor three-point draw bar (3). The agricultural implement is fixed by a vertical pivot (6) which allows sideways movements. To prevent swing during transportation, a plate (12) is welded to the attachment arm (2). This has an elongated opening (11), housing the end (10) of the pivoted lever. When the implement is raised its arm presses the lever end upwards into one of two alternative recesses (17) and locks it. A plate (20) is manually locked under the lever end for safety.
