摘要： A cutting device for cutting plants is provided, and includes at least one cutting unit. The cutting unit has at least one probe element, which is fastened to a holding element and is intended for determining an extent of a plant. Furthermore, the cutting unit has at least one cutting element, which is fastened to a further holding element and is intended for cutting the plant depending on the extent. The cutting unit has at least two frame coupling elements. At least one of the holding elements is coupled to a cutting device frame by means of the frame coupling elements. The holding elements are arranged movably relative to one another.

摘要： This invention comprises a device for measuring root pulling force (RPF) in a plant. The RPF device comprises a plant grasping mechanism, as well as a force measurement sensor. In certain embodiments, the device is automatic, so that the “hand of man” is not required to exert force on the plant while the root pulling force of the plant is being measured. Also disclosed is a root pulling force motion mechanism, which brings the RPF device into proximity of a plant to be measured. Further disclosed is a method for measuring root pulling force of a plant.

摘要： A self-lubricating harvester machine for harvesting row crops that is connected to and powered by a tractor includes a plurality of pairs of grasper-cutter devices that are arranged circumferentially in a protruding fashion from the peripheral of a wheel-like structure. Power-driven mechanisms are associated with the two formed wheel-like structures and operate the grasper-cutter devices that grasp, cut and pull the row crop as the devices contact the ground and that move to an open position upon leaving the ground to discharge the row crops.
