This invention generally relates to blades.
Disc mowing machines are utilized to cut a crop while moving through a stand of the crop. Examples of such machines are shown for example in U.S. Patent Application Publication No. 2013/0111863. The disc mowing machines may be either self-propelled or pulled, for example, by a tractor.
As disclosed in the '863 publication, current disc mowing machines cut agricultural material using a severing blade that is rectangular in shape with a mounting hole toward one end of the blade. The severing blade is rotatably mounted to a plurality of rotating mower discs. The portion of the blade away from the mounting portion has a beveled edge and this portion of the blade impacts and cuts the crop as the disc rotates.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:
FIG. 1 is an illustration of a tractor manipulating a mowing machine through a crop;
FIG. 2 is a partly schematic isometric illustration of a disc mower cutter bar including a plurality of discs holding a plurality of mower blades;
While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
FIG. 1 illustrates a tractor 10 operating a mowing machine 12 through a stand of crop 14. The mowing machine 12 may either be self-propelled or as shown here manipulated and powered by the tractor 10.
FIG. 2 illustrates a mower disc cutter bar 16 that forms a part of the mowing machine 12 shown in FIG. 1. The mower disc cutter bar 16 supports a plurality of mower disc assemblies 18, which in turn support a plurality of mower blades 20 (also known as cutter blades and/or knives). The blades 20 described herein may be used in various applications such as cutting vegetation including lawn and turf applications, cutting crops, and various other agricultural operations for which blade 20 is well suited. Accordingly, the aforementioned uses for blade 20 are intended as non-limiting examples.
