A cutter wheel for use with a stump cutter having a drive assembly includes a drive plate having first and second sides and a perimeter. A cutter is attached to one of the sides, the cutter having a contact surface configured to engage the side. The cutter has a leading surface and a trailing surface, and a leading mounting hole defining a leading axis and a trailing mounting hole defining a trailing axis. A reference line passes through the leading axis and the trailing axis. A portion of the perimeter of the drive plate is in a zone defined by: a pair of radial lines extending from the leading axis at angles of 20 degrees and 40 degrees radially outward from the reference line, and a pair of arcs 0.25 in. radially outward and inward, respectively, from the leading surface.

A device for separating conglomerates that consist of materials of different densities is provided. The device has a rotor chamber in which a rotor shaft is mounted so as to be rotatable about a vertical axis, on which rotor shaft striking tools are arranged one beneath the other in at least two planes, which striking tools are set into rotational movement by the rotor shaft such that the conglomerates filled into the rotor chamber from above are captured and separated by the striking tools. The rotor chamber widens conically downward, and the outer radius of the striking tools increase from top to bottom, such that the spacing of the radially outer end edges of the striking tools from the chamber wall facing the striking tools is substantially the same in the individual planes during operation.

A device for processing feed material, with a housing enclosing a processing space in which a rotor rotatable about the axis of rotation is arranged. The rotor has a rotor disk at which circumference a plurality of axially disposed impact plates is arranged uniformly distributed. A coaxially arranged processing path surrounds the impact plates while maintaining a working gap. Via a material inlet, the device is fed in the axial direction with feed material centrally ending in the processing space, which upon deflection in the region of the rotor disk is fed in the radial direction to the working gap. To ensure complete and gentle processing of the feed material while maintaining its original taste, smell and color, the processing path is part of a basket rotating about the rotational axis.

The rock crusher has hammers mounted to a rotor and anvils mounted to its casing. First and second anvil sets define a convex surface arrangement facing the rotor and second and third anvil sets define a concave surface arrangement facing the rotor. The anvil sets are oriented to reduce compaction of rocks in the infeed portion of the crusher, and to reduce compaction of aggregate in the casing of the rock crusher. In relation to the movement of each hammer along their work sector, the two operations mentioned above are carried out before a third portion of the work sector wherein rocks are directed to rebound and impact the hammers head-on along the work circle of the hammers. The rock crusher is directly driven by the engine of a potato harvester, wherein the engine, the fan of the harvester and the rock crusher share a common inertia.
