A beet scalper includes an upwardly biased parallel arm linkage, a boom, having an upper end coupled to the parallel arm linkage and a lower end bearing a beet scalping blade, and a locking mechanism, holding the boom in a downward operating position. Forward deflection of the lower end of the boom releases the locking mechanism, allowing the boom to rise to a tripped position under force of a biasing mechanism associated with the parallel arm linkage.

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.

A header to be coupled to an agricultural machine, such as harvesters of tall and stemmed plants, and sugar cane and sorghum. The header includes at least one base cutting assembly mounted in a floating manner in relation to a structural frame of the header through at least one pantographic arm and at least one actuator.

In one aspect, the present subject matter is directed to a header-based harvesting system for agricultural harvesters that includes a header configured to be removably coupled to a front end of a harvester. The header includes a header frame and a base cutter assembly coupled to the header frame in a floating arrangement. Additionally, the system includes an actuator coupled between the header frame and the base cutter assembly, and a hydraulic circuit in fluid communication with the actuator. The hydraulic circuit is configured to allow pressurized hydraulic fluid to be supplied to the actuator for regulating the floating movement of the base cutter assembly relative to the header frame.

A tractor-assisted multi-row harvester for root vegetables includes adjacent pairs of a lifting share and a picker and a pair of traction assemblies, for example in the form of endless track assemblies, one of which being behind and registered with at least one of the adjacent pairs of a lifting share and picker and being motorized and energized so as to compensate at least partially for pressure on the lifting shares. The harvester includes sensors on the motorized traction assembly and/or on the lifting shares that generates signal(s) indicative of the pressure on the lifting shares and that is used to control the motorized traction assembly to compensate for the pressure.

A harvesting device includes a support defining an uprooting position of the harvesting device, and an uprooting section comprising at least two uprooting units, each uprooting unit having at least one uprooting element, each uprooting unit being adapted to uproot root crop. At least one of the uprooting units is mobile with respect to the support between an active position and an inactive position, the active position being a position in which the uprooting unit is able to uproot beet crop in a field having a field surface when the harvesting device is in the uprooting position, the inactive position being a position in which the uprooting unit is unable to uproot beet crop in the field when the harvesting device is in the uprooting position.
