Embodiment Construction

[0019] The embodiments of the present disclosure described below are not intended to be exhaustive or exclusive or to limit the disclosure to the precise forms disclosed in the following detailed description. Rather, the embodiments were chosen and described so that others skilled in the art can understand and appreciate the principles and practice of the disclosure.

[0020] now refer to Figure 1A , the large square baler 12 can be towed across the field by the agricultural vehicle 10 . (It should be understood that various other configurations are also possible. For example, the disclosed systems and methods may be used with various balers or other harvesting equipment.) The baler 12 may include a housing 14 which may generally shield the baler Various internal components of the machine 12. As baler 12 traverses a field (e.g., towed by vehicle 10 via linkage 10a) and encounters a windrow or other arrangement of material (not shown), pick-up assembly 16 may collect the mate...

Abstract

A harvesting machine including a frame, a rotor assembly rotatably coupled to the frame configured to move crop material, and a plurality of knives movably attached to the harvesting machine. The rotor assembly includes a plurality of spaced apart rotating blades, wherein one or more of the plurality of knives extends into the spaces between the blades. Each of the plurality of knives includes a knife body and a cutting edge having a plurality of teeth, wherein each of the teeth includes a scallop or valley. Each one of the plurality of valleys extends from the knife body to the leading edge of one of the plurality of teeth, wherein adjacent valleys are located on opposite sides of the knife body. The valleys are lined with a wear resistant material to increase the longevity of the cutting edge and cutting ability.

Description

technical field [0001] The present invention relates to a work machine for harvesting crops, and more particularly to a harvesting machine for cutting crops, which includes a pre-cutting knife. Background technique [0002] Hay and forage equipment is used to process plant material and includes mowers, conditioners, mulchers, stockers and balers for dry forage and silage use. Hay systems, such as square balers, include a picking mechanism that picks up crop material from the ground and supplies it to the bale forming chamber. The bale forming chamber receives crop material and includes a plunger or piston that applies an axial force to the pile of crop material to form a substantially square bale. A plunger or piston may further apply force to the surface of the bale to further densify the bale. Once the bale reaches a certain or desired density, the bale can be pushed out and extruded from the rear of the baler. [0003] Large square balers, round balers and feeder carts...
