The invention relates to a cutter blade for mowers of harvesting machines the cutter bevel of which comprises two zones of different inclination relative to the blade leaf plane wherein between the zone molded to the cutting edge and the zone extending to the upper blade plane a gradation is provided. It relates furtheron to a method for the production of said cutter bevels on cutting blades of mowers which comprise two zones having different blade angles relative to the blade leaf plane wherein in a first embossing process the zone of the cutter bevel extending to the upper blade plane is pressed into the blade blank in parallel to the cutting edge provided and in a subsequent embossing process, the zone extending to the cutting edge is molded on and the embosssing portion extending beyond the lower blade leaf plane is ground away.

Cutter blade for mowers of harvesting machines and a method for the

The invention relates to a reaping-cutter blade for reaping cutters of harvesting machines, with an orifice (11) made, if appropriate, in the base edge, wherein two or more orifices (12) are provided in the blade leaf in front of the cutter bar (4). The orifices can at the same time appropriately have walls which, on one side of the blade, are at an angle of less than 90.degree. relative to the plane of the blade leaf.

The invention relates to a cutter for cutter-bar mowers of harvesting machines, with a top cutter (1) and bottom cutter (2) stamped out of flat material and connected to one another in front of the blade gap (3) by projection welding, a layer of material (14) being applied by additional welding to the point of connection (12), directed towards the cutter tip, between the top cutter (1) and bottom cutter (2). The invention also relates to a process for producing such a cutter.

The invention relates to a cutting finger for finger-bar cutters of harvesting machines with a top finger and a bottom finger stamped out from flat material and connected to one another in front of the blade gap, in which cutting finger the top finger and/or the bottom finger are deformed in the region located in front of the blade gap and are connected to one another by welding.

Cutting finger for finger-bar cutters

Holding means for grain lifters, support skids or the like for fastening the latter to the cutter mechanism of a harvesting machine, comprising a device provided at one end of the flat support leg to be secured to the mower cutter bar and a retention bracket provided in spaced relationship from the one end on the support leg and embracing, if necessary under bias, the cutter finger, wherein said retention bracket includes two legs provided on each side of said cutter finger, and a locking device connecting said two legs and overlapping said cutter finger.

Holding means for grain lifters, support skids and the like

The invention relates to a cutter finger for cutter bar mowers comprising a lower portion bolted at the end to the cutter bar and including a forwardly projecting cutter finger tip from which the upper portion of said finger extends to the rear thus forming the cutter blade slit and constituting together with said lower portion the counter edges for the mower knife wherein said upper portion of said finger is extended to, and supported at, and if necessary bolted at said cutter bar.

Cutter finger for cutter bar mowers

The invention relates to a mechanism for swivelling and spring-mounting a machine sub-assembly, mounted to swivel about an axis of rotation, for example the cutting bench of a harvester thresher, which bench is supported on the movable frame of the machine by way of a lifting unit, consisting of a lifting cylinder and piston, and a spring element, a spring element of limited stroke being provided between the lifting unit and its support, and means, such as a hydraulic force transducer or the like, also being provided for the purpose of varying the spring force of the spring element.

Mechanism for swiveling a machine sub-assembly

Control device for guiding a hydraulically operated cutter mechanism of a harvesting machine, particularly a combine harvester, at a preselected height above the ground, said cutter mechanism being connected via a connecting member and two series-connected spring elements to a stationary portion of the harvesting machine, the spring force of at least one of said spring elements being preselectable by means of an adjustment lever, while between said spring elements a switching member is arranged which depending on the position thereof acts on a switch actuating either a raise valve or the lower valve of the lifting cylinder or takes a neutral position, wherein said two spring elements connected with one of their ends to said cutter mechanism are connected via said connecting member to said adjustment lever provided on the stationary portion of said combine harvester.

Control system and method for combine harvesters

The invention relates to a grain lifter for the cutter mechanisms of harvesters having a support leg of solid flat material which carries on one of the ends thereof the stalk lifting bar and at the other end thereof is secured, by means of a holder embracing the mower finger tip, to the mower finger and to the mower finger holder, wherein said support leg is stiffened by having a non-linear cross-section within the part of the support leg which is fixed to the holder which embraces the mower finger tip.
