<p>The invention refers to an agricultural harvesting device, such as e.g. a swather (20) and tedder(21) or in general to devices with at least one vertical axis and a contacting-support unit (1) on which is positioned a height-adjustable rotating unit with suitable working apparatus. It concerns an agricultural harvesting device with a contacting-support unit (1) which is via an undercarriage beam (16) and the supporting axle (25) in movable contact with the installation plate (15) on which, in the corresponding pivots (12, 14), are swivel-mounted two oscillating links (8, 9). The latter are linked one to another by a large pin (11). The mentioned contacting-support unit (1) consists of at least four wheels (3, 4) which are connected through oscillating links (8, 9) and the linking pin (11) or beam (11') of the linking pin (11). On the installation plate (15) the oscillating links (8, 9) are swivel-mounted on pivots (12, 14) which create the possibility of oscillation in the vertical plane, while the installation plate (15) forms a swivel union with the undercarriage beam (16) by means of the axle (25), providing the possibility of oscillating around the vertical axis.</p> |
