Systems and methods for a dual-blade agricultural grinder are disclosed. A dual blade grinder comprises a casing, a hopper, a cutting mechanism, a chute, and a display. The grinder is configured to cut a plant to a desired particle size. The casing is configured to provide rigid structural support for components of the grinder and provide a safety barrier between the user and the cutting mechanism. The hopper is configured to store and distribute a plant to the cutting mechanism. The cutting mechanism comprises a static blade with one or more serrated edges and one or more plain edges, a floating curved blade, and a particle screen. The display is configured to accept input from a user operating the grinder, and to control operational settings of the grinder. The grinder and its components may be comprised of a food-grade quality steel configured to resist bacterial growth.

The invention relates to a bale breaker (1) for a bale (2) of hay, straw, litter and/or fodder, comprising support means (3) for the bale (2) and breaker means (4) adapted to detach hay, straw, litter and/or fodder from a bale (2) provided on the support means (3) and to transport it to discharge means (5) arranged downstream of the breaker means (4), wherein feed means (6) for feeding a bale (2) provided on the support means (3) in a feed direction (Z) toward the disintegrating means (4) are associated with the support means (3), and wherein feed drive means (7) for driving the feed means (6) and disintegrating drive means (8) for driving the disintegrating means (4) are further provided, wherein control devices (9) are associated with the feed drive devices (7) and/or the opening drive devices (8) and/or the discharge devices (5), which are designed to control the feed drive devices (7) and/or the opening drive devices (8) and/or the discharge devices (5) in such a way that a malfunction or disturbance, such as in particular a jam or a blockage by the bale (2), in particular at the opening devices (4) and/or the discharge devices (5), is avoided or eliminated. Furthermore, the invention relates to a bale unraveling method in which a bale (2) of hay, straw, litter and/or fodder is transported on support devices (3) by means of their feed devices (6) driven by feed drive devices (7) to unraveling devices (4) driven by unraveling drive devices (8), which unravel hay, straw, litter and/or fodder from the bale (2) and transport it to output devices (5), wherein the feed drive devices (7) and/or the unraveling drive devices (8) and/or the dispensing devices (5) are controlled by means of control devices (9) in such a way that a malfunction or disturbance, such as in particular a jam or a blockage by the bale (2), in particular at the unraveling devices (4) and/or the dispensing devices (5), is avoided or eliminated.
