A reducing element system includes a reducing element having a main body defining a fastener opening, a leading face defined by the main body, and a trailing face defined by the main body. The trailing face includes a pair of mating features equally spaced from the fastener opening and having a generally arcuate cross-section perpendicular to a fastener axis. The system further includes a reducing element mount having a main body defining a fastener opening, a leading face defined by the main body, and a reducing element mount mating feature defined by the leading face. The mount mating feature has a generally arcuate cross-section perpendicular to the fastener axis. The reducing element mount mating feature of the reducing element mount is configured to mate with at least one of the mating features of the reducing element when the reducing element mount is mated with the reducing element.

A plant vine chopper rotor drum assembly has a plurality of rotor rings spaced along, encircling, and attached to the longitudinal outer surface of a rotatable main drum tube. Each rotor ring has one or more pairs of angled mounting tabs that alternate to the left and to the right to the general plane of respective rotor ring; and the rotor rings are distributed in a cutting zone along and surrounding the longitudinal rotational axis of the drum tube with each mounting tab having a generally planar cutting blade attached. The angled blades distributed around the outer circumference of the ring cooperate one with another during operational rotation of the drum to guard each blade and the drum against the wrapping of clogging fibrous strands and other clogging material around the drum.

A mulch cutting and spreading machine is a machine that is designed to be able to suction mulch out of the bed of a vehicle that is towing the mulch cutting and spreading machine and to simultaneously suction and chop the mulch and discharge it through a discharge hose that is directed by the user. The mulch or other such material can be then blown or spread over an area quickly in one combined action.

Device for shredding fibrous plant material, in particular hay, straw or silage, comprising a feed for receiving the plant material, a conveying unit and a shredding unit, wherein the conveying unit comprises at least one catch for loosening plant fibers from the fed plant material, and for conveying the plant fibers to the shredding unit, wherein the shredding unit comprises at least two spaced-apart stationary knives, wherein the conveying unit is designed such that the at least one catch can be moved through the spaced-apart stationary knives.

A land preparation tool includes a tool body having a cutting surface, a mounting surface, an opening, and a channel. The cutting surface has a blade positioned at a distal end thereof. The mounting surface has a non-planar profile and is disposed on the tool body opposite the cutting surface. The opening is disposed on the mounting surface and the channel extends from the opening at least partially into the tool body. Other embodiments are described and claimed.

A land preparation tool. The land preparation tool can include a tool body, and the tool body can include a cutting surface, a mounting interface disposed along a side of the body opposite the cutting surface, a first angled surface that sweeps backward from the cutting surface toward the mounting interface, and a second angled surface that is disposed on a side of the cutting surface opposite the first angled surface and sweeps backward from the cutting surface toward the mounting interface. The tool can also include a blade disposed on the same side of the tool body as the cutting surface and a channel disposed into the mounting interface and extending into the tool body. The mounting interface can include a nonplanar profile.

A land preparation tool. The tool body can have a longitudinal axis, and include a first imaginary plane and a second imaginary plane. The first and second imaginary planes can intersect orthogonally at the longitudinal axis. The tool body can also include a concave cutting surface tapering from a proximal midpoint to a distal edge comprising a circular blade, and a multi-faceted surface mounting interface disposed on the tool body opposite the cutting surface. The mounting interface can have a plurality of beveled surfaces defining a first pair of V-shaped surfaces and a second pair of V-shaped surfaces, wherein a first apex of the first pair of V-shaped surfaces is disposed in the first imaginary plane and a second apex of the second pair of V-shaped surfaces is disposed in the secondary imaginary plane. A channel can be disposed into the mounting interface and extend into the tool body.

A covering soil mulching apparatus according to an embodiment includes a soil scattering part at the rear end of the agricultural machine and including a scattering part frame and a scattering unit provided on a lower end side of the scattering part frame and scattering soil on a floor, a mulching film laying part including a laying part frame connected to a rear end side of the soil scattering part and a mulching film holding part having a mulching film wound around the mulching film holding part and spreading the mulching film on the floor, an oscillating plate above the mulching film holding part and guiding the scattered soil to be transported to a rear side and laid on an upper surface of the mulching film, and a soil oscillating part including oscillator for oscillating the oscillating plate to prevent formation of a soil wall on the oscillating plate.

A mulching and chipping attachment includes a deck having a top plate. A cutting disk is attached to the deck. The top plate includes an opening that exposes a portion of the cutting disk. A guide chute is attached to the deck, and is disposed over the opening. The guide chute includes a feed system. The feed system includes a first roller, and a reactionary member operable to react against the first roller to secure a log therebetween. The first roller and the reactionary member cooperate together to grasp and controllably feed the log through the opening. The first roller or the reactionary member may be moveable relative to the other, to adjust a throat distance therebetween. An anvil may be disposed at a rearward edge of the opening, and extend downward to define a chip cutting height between the anvil and the cutting disk.
