Abstract: Ear lifter for a mower of a harvesting machine with finger guards attached to a cutter bar. The ear lifter has a support rail with a first end for attachment to the cutter bar, a stalk lifter connected to a second end of the support rail and a locking lever, wherein the locking lever has a support surface for support on one of the finger guards and can be fixed in at least two positions relative to the support rail in order to set a distance between the finger guard and the support rail.

Abstract: A harvesting machine for cutting and processing crop, including a sensor arrangement, method for determining properties of crop when processing the crop with a harvesting machine, and method for determining properties of crop in a field.

Abstract: A method of manufacturing a knife blade for a cutter knife of an agricultural harvesting machine, wherein a substantially disk-shaped blade blank is provided in a providing step, said blade blank having a bottom side extending in a first plane (YZ1) and a top side extending in a second plane (YZ2), wherein a hole connecting the first plane (YZ1) with the second plane (YZ2) is made in the blade blank, wherein in a reshaping step an area of the blade blank surrounding the hole is deformed in such a way that a top contact surface surrounding the hole is formed in a third plane (YZ3), wherein the third plane is more distant from the first plane than the second plane (YZ2) in a normal direction (X) perpendicular to the first plane (YZ1).

Abstract: A cutting assembly for an agricultural or forestry cutter, the cutting assembly comprising a lower member and an upper member, which together form at least one finger guard extending along a longitudinal axis, wherein a blade gap is formed between the lower member and the upper member, and a knife, which is guided in a reciprocating manner in the blade gap in a drive direction transverse to the longitudinal axis, and which has at least one cutting edge.

Abstract: A support rail of an ear lifter for crops, having a major direction of extension, wherein a portion formed as a skid is disposed between a first end and a second end of the support rail, the portion formed as a skid being adapted to be guided with an outer side over a ground; and an ear lifter for a mower of a harvesting machine, comprising a stalk lifter and a support rail supporting the stalk lifter.

Abstract: Ear lifter for crops having a support bar, wherein the support bar extends in a major direction of extension and has a fastening portion, a middle portion and a skid portion arranged one after the other in the major direction of extension.

Abstract: A method for analyzing the operating state of a cutting device for mowing crop, the cutting device having at least one mowing knife having cutting edges which interact with counter cutting edges of the cutting device, including: detecting of a signal representing the stroke position of the mowing knife; detecting a signal representing the knife force for driving the mowing knife as a function of the stroke position, and determining crop and/or cutting system properties on the basis of an evaluation of the signal representing the knife force as a function of the stroke position.

Abstract: A cutting device for an agricultural harvesting machine including: a drive; a transmission arrangement having an input element drivingly connected to the drive and driven reciprocatingly by the drive along an input travel; and a knife having a plurality of cutting edges, the knife being drivingly connected to and driven by an output element of the transmission arrangement along an output travel longer than the input travel, is driven in a reciprocating motion in such a way that the cutting edges of the knife pass in each case at least two counter-cutting edges of the cutting device when moving in one direction along the entire output travel.

Abstract: A knife blade for a cutting knife of an agricultural harvesting machine, with a blade top side and a blade bottom side, wherein a surface of the blade bottom side is composed of a planar surface arranged in a plane and a recess region extending above the plane. A height of the knife blade corresponds to a maximum distance between the blade top side and the planar surface in a direction normal to the plane, a material thickness of the knife blade corresponding to a distance between the blade top side and the blade bottom side, and a method of manufacturing a knife blade.
