Agricultural machine with an improved terrain following for the work elements

摘要

An agricultural machine for working soil or for sowing seeds, including a trailed chassis and work elements distributed on a longitudinal bar in plural sections, the longitudinal bar including at least two primary beams extending substantially transversely to a direction of advance in a work configuration. A secondary beam is connected to each primary beam by two connection devices, the secondary beams support the work elements, and each secondary beam rests on the soil by two support wheels and is configured to move freely during work to follow a profile of the terrain.

1. An agricultural machine for working soil or for sowing seeds, comprising:
a trailed chassis and work elements distributed on a longitudinal bar in plural sections, the longitudinal bar including at least two primary beams extending substantially transversely to a direction of advance; and a secondary beam connected to each primary beam by two connection devices that are independent of one another such that, in a first position, a first end of the secondary beam is closer to the primary beam and, in a second position, a second end of the secondary beam is closer to the primary beam, the secondary beams supporting the work elements, and each secondary beam resting on the soil by two support wheels and being configured to move freely to follow a profile of the terrain.
