A material reducing apparatus includes a reducing head that includes a rotary reducing component that carries a plurality of cutters. The reducing head includes a thrown object deflector positioned proximate the rotary reducing component. The thrown object deflector is configured to limit at least one of a distance and a direction that objects can be thrown by the rotary reducing component.

A ground milling machine, comprising a machine frame, an operator platform, a drive engine, travelling apparatuses, a milling unit, a conveying apparatus for transporting milled material from the milling unit to a discharge point with a transfer conveyor and a downstream loading conveyor, and with a material transfer apparatus arranged in a material transfer region between transfer conveyor and loading conveyor, which material transfer apparatus is configured so as to direct milled material from the transfer conveyor to the loading conveyor, the transfer conveyor and the loading conveyor each comprising a support frame, wherein the material transfer apparatus comprises a milled-material-directing transfer chute, wherein the transfer chute has a chute guide surface extending at least partially in a horizontal direction and running in an at least partially descending manner from the transfer conveyor to the loading conveyor, and wherein the transfer chute is arranged at least partially immovably with respect to the transfer conveyor, and a method of conveying milled material by means of a conveying apparatus of a ground milling machine comprising a material transfer device with a transfer chute.

An impact mill (10) has an inlet (12) for material to enter the mill, an impact mechanism (16, 50) arranged to rotate about a rotation axis and being operable to pulverise the material after entering through the inlet, and an outlet (154) for discharge of pulverised material. Blockage sensors (Bj), vibration sensors V, torque sensors Tn, temperature sensors and proximity sensors may be selectively incorporated into the mill.

A roof removal machine may include an auger assembly at least a first helical auger flight coupled to a central axle, and a plurality of blades coupled to an outer edge of the auger flight. A motor is operably coupled to the auger assembly and configured to rotate the auger assembly about the axle in at least a first direction of rotation. The blade edge of each of the blades is oriented transverse to the first direction of rotation. In some examples, a second helical auger flight is also coupled to the central axle, and the two auger flights may be oppositely-handed with respect to each other, such that roof debris is moved toward a central extraction port.

A cutter head comprises a drum body with a plurality of mounting slots defined in an outer face of the drum body. A plurality of cutter bits are removably connected to the drum body in at least a portion of the mounting slots. Filler plates are connected in any mounting slot that does not have a cutter bit connected therein.

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.

Disclosed embodiments include diesel-electric powered, substantially heavier (e.g., 120 ton), larger (e.g., 11 8 and 12 6 diameter wheels), and more powerful (e.g., 250-350 hp per wheel) landfill compactors. Disclosed embodiments also include an integral hammer mill, oriented in an upside-down configuration to additionally compact landfill waste.

A stump grinding system that includes a vehicle and a stump grinder adapted to engage with the vehicle. The vehicle has a first end, a second end opposite to the first end, and a longitudinal axis defined therebetween. The stump grinder includes a chassis operably engaged with the vehicle at one of the first end and the second end. The stump grinder also includes a body operably engaged with the chassis and a grinder wheel operably engaged with the body and partially disposed outside of the body from the vehicle. The stump grinder also includes a drive assembly operably engaged with the grinder wheel and the body. The grinder wheel of the stump grinder is configured to rotate in a plane that is orthogonal to the longitudinal axis of the vehicle.

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.
