A system and method for an engaging tool. Removing debris, trees and clearing land and paths requires the use of specific tool and machinery. To grind, break and shred wood, the machines must be fitted with proper attachments and engaging tools. One tool includes a front a front face and a back face connected by two opposing side faces and an opposing top face and base face. The front face has a concave shape and an outer channel which extends inwardly into the front face. The front face also has a tube a tube extending outwardly from said front face. The tube is located within the outer channel.

A horizontal grinder chipper with interchangeable rotors which allows for rapid changing of said interchangeable rotors. Where the interchangeable rotors each are in the form of a cassette which can be easily inserted into and in between a first frame portion 1302 and a second frame portion 1303. A hydraulically actuated pivoting clamshell cassette covering upper portion 920 configured to pivot to an open orientation for removal of a first rotor cassette and for insertion of a second rotor cassette.

A cutter head for an underwater granulating installation has a rotor body having a plurality of cutter-retaining arms. Each of the plurality of cutter-retaining arms adjoins the outer circumference, and one cutter element is fastened on each of the plurality of cutter-retaining arms, where the rotor body in the region of each cutter-retaining arm includes at least one receptacle recess configured to receive a fastening element. The cutter element is integrally configured to have a basic body and at least one blade body. The basic body is positioned on a lower bearing face of the rotor body, and the lower bearing face extends up to at least one of the plurality of cutter-retaining arms. The at least one of the plurality of cutter-retaining arms on an upper side is overlapped by the cutter element, and the blade body includes at least one cutting edge molded thereon.

The present invention relates to a brush cutting head for a brush cutter. The brush cutter head includes a cylindrical support body that has a first end, an opposed second end and an intermediate portion extending therebetween. The intermediate portion has a curved surface that defines the circular cross-section of the cylindrical support body. A plurality of collars is mounted to the cylindrical support body at spaced intervals along the intermediate portion. Each collar extends radially from the curved surface of the cylindrical support body. Additionally, each collar cooperates with an adjacent collar to define a mounting station between the adjacent collars. The brush cutter head further includes a plurality of cutting tooth assemblies carried on the outer surface of the cylindrical support body. Each cutting tooth assembly has a cutting tooth for placement within the mounting station and a mounting assembly engageable with the adjacent collars to secure the cutting tooth in the mounting station.

A modular system for performing a plurality of crushing and grinding processes, including: a plurality of interchangeable milling heads, each interchangeable milling head having a milling mechanism configured to perform one of the plurality of crushing and grinding processes when driven; a driving unit including a driving motor having a range of motor characteristics; and a connecting unit configured to functionally connect one of the interchangeable milling heads to the driving motor such that, when connected, the one of the plurality of interchangeable milling heads can perform the one of the plurality of crushing and grinding processes. Each of the plurality of interchangeable milling heads further includes an adaptor unit configured to connect the milling head to the connecting unit and for converting the range of motor characteristics of the driving motor into the milling driving characteristics of the connected interchangeable milling heads.

A secondary shredder can include a rotor assembly that employs a modular rotor design. Each rotor of the rotor assembly can include a number of blades that are symmetrical around a horizontal and a vertical axis. Each rotor can include a number of radial extensions forming gaps into which the blades insert. The blades can be secured within the gaps by wedges that apply an inward force against the blades when the wedges are secured into the gaps. The radial extensions and blades can include keyways into which keys insert to prevent the blades from escaping the gaps. The secondary shredder may also include a stationary knife assembly that includes multiple stationary knives that are positioned on the same side of the rotor assembly.

A material processing tool assembly includes a tool for material processing having a base section and a processing section extending from the base section; and a tool mounting block mountable on an outer surface of a support base. The mounting block has a base surface and a tool mounting surface intersecting the base surface. The base surface has a protuberance extending away therefrom and spaced apart from the tool mounting surface to define a tool receiving gap between the protuberance and the tool mounting surface. The base section of the tool is snugly received in the tool receiving gap between the tool mounting surface and the protuberance in abutment with the tool mounting surface, the processing section of the tool extending past the protuberance. A displaceable material processing head and method of mounting a material processing tool to a mounting block secured to a displaceable head are also discussed.

A tool assembly for a comminuting apparatus having knives secured to the periphery of a comminuting rotor is provided including an integral knife carrier adapted to be secured to the comminuting rotor of the comminuting apparatus having a supporting surface for support against a seat formed at the rotor and an abutment face with a non-threaded through bore extending therefrom. The assembly includes a knife detachably secured to the knife carrier, a screw connection between the knife and knife carrier, and a screw bolt extending through the through bores of the knife and the knife carrier, wherein a screw nut is screwed onto a portion of the screw bolt extending beyond a trough bore of the knife carrier for clamping the knife to the knife carrier.

A shredder blade assembly is disclosed having a rotor configured to be mounted on a rotating shaft, the rotor having opposing faces with a plurality of angled knife receptacles and a plurality of knife inserts mounted within the plurality of knife receptacles. Each knife insert has two opposing faces and each opposing face comprises three cutting edges such that each knife insert has six cutting edges. Only one of the cutting edges is exposed at an outer peripheral edge of the shredder blade assembly during use. The knife inserts are configured to be removed, rotated (and flipped as needed), and re-mounted within the plurality of knife receptacles to expose another of the cutting edges at the outer peripheral edge of the shredder blade assembly. The knife insert may be triangular and mounted to expose one vertex to create a plurality of tooth/hook projections.
