A folding rear cross system for a harvesting device having a harvesting direction and a discharge includes first and second substantially linearly aligned reversible endless belt sections, positioned near the discharge and oriented transverse to the harvesting direction. Each belt section has an inboard end disposed in overlapping relationship with the inboard end of the other. A lifting device is attached to selectively lift and lower the first and second reversible endless belt sections to reverse the overlapping relationship

A root crop harvester apparatus includes a transverse frame, supported to move above ground in a harvesting direction and oriented generally perpendicular to the harvesting direction. A plurality of pairs of generally upright, spaced apart puller wheels are connected to the transverse frame in a trailing orientation, having a substantially common rotational axis, and configured to contact the ground, each pair having a pinch point therebetween. The transverse frame is pivotal about an axis that is substantially aligned with the substantially common rotational axis, whereby rotation of the transverse frame collectively rotates all of the pairs of puller wheels about the common rotational axis and thereby adjusts a location of all of the pinch points with respect to the harvesting direction.

The application describes a system for harvesting seaweed. The system includes a frame structure (202) and a first device mounted (204,206) on the frame structure. The first device receives a tube net comprising the seaweed and selectively separates its apical tips protruding out of the tube net. The systems also includes a second device (212,214) mounted on the frame structure for receiving the tube net comprising partially harvested seaweed.

A method is provided for controlling the operation of a machine for harvesting root crop. At least one optical image-capturing unit captures at least one test image of harvested material comprising root crop which is moved along relative to a machine frame by means of at least one conveyor element. A conveying speed of the conveyor element is set on the basis of a test data set which is generated using the test image or formed by means of the latter. An evaluation device generates, on the basis of the test data set, a conveying speed signal, independent of a speed of the harvested material, for setting the conveying speed.

In the case of a mounting device for mounting a support arm, which moves a lifting tool, on a harvesting machine, a cylindrical bushing is mounted on a machine part. The bushing is enclosed by a retaining element on which the end of the support arm opposite the lifting tool is fixed. The bushing has a through-hole that receives a machine part and has an axis of symmetry extending eccentrically relative to the axis of rotation of the cylindrical bushing.

Depth of penetration of a soil coulter is detected using a sensor being mounted on the side of the disk adjacent the edge such that the sensor as the disk rotates is located above the surface of the soil during a first part of its rotation and is located below the surface during a second part of its rotation. The sensor issues a signal which changes in response to whether the sensor is above or below the soil surface which is received by a controller which calculates from the signal a first time when the sensor enters below the soil surface and a second time when the sensor departs the soil surface and calculates from the first and second times the depth of penetration of the coulter in the soil. The system can also detect variations in depth indicative of a value of surface roughness.
