摘要： Described are various embodiments of a tree stump and root removal attachment assembly for use on a hydraulic work vehicle. In one embodiment, the attachment assembly comprises a tree stump removal device, comprising an elongated single fork portion for piercingly engaging the ground under tree stump and to push at least a portion thereof out of the ground, and a vertically oriented cutting blade positioned at a designated distance from an end of the single fork portion, the cutting blade comprising a concavely shaped sharp cutting edge bounded at two ends thereof by substantially pointed ends. The assembly further comprises a hydraulic ram mechanically coupled to the cutting blade, to move the cutting blade up and down to cut said least a portion of said tree stump; and a mounting plate removably attachable to the arms of the work vehicle for removably securing the tree stump removal device thereto.

摘要： An apparatus for facilitating processing of plant material is disclosed. The apparatus includes a base, a cutter disc rotatably coupled to the base such that the cutter disc is configured to rotate about an axis of rotation relative to the base, the cutter disc having an upper side including a plurality of radially spaced teeth, each of the plurality of teeth configured to travel on a respective cutting path to engage and shear the plant material when the cutter disc rotates. The apparatus includes a shearing governor rigidly coupled to the base, the shearing governor including one or more cutting edges, each of the one or more cutting edges extending adjacent to the cutting paths of at least two of the plurality of teeth and configured to shear the plant material when the cutter disc rotates. Other systems and apparatuses are disclosed.

摘要： The invention relates to a work device having a body with an attachment arrangement to attach the work device to a set of booms of a work machine. A pair of jaws fitted to the body includes two jaws arranged to form a grab. A first jaw is fixed to the body and a second jaw is pivoted rotatably to the body to open and close the grab. The rotatable jaw is arranged to be acted on by a hydraulic actuator, to open and close the grab. Between the hydraulic actuator and the rotatable jaw is a wide-angle pivot setup. An arm mechanism, equipped with two pivots fitted to a jaw arm is arranged to belong to the wide-angle pivot setup. In addition, the wide-angle pivot setup is arranged to include a rotatable lever arm fitted between the jaw arm and the body. The rotation angle of the movement created in the rotatable jaw by the wide-angle pivot setup has a magnitude of more than 120°.

摘要： A system, for providing a rotary power to an implement of a machine, includes a first motor control valve associated with a first motor of the machine and a second motor control valve associated with a second motor of the machine. The first motor control valve is configured to be actuated at a first shift point to shift the first motor such that the first motor and the second motor switch between a first implement drive speed and a second implement drive speed. The second motor control valve is configured to be actuated at a second shift point to shift the second motor such that the first motor and the second motor switch between the second implement drive speed and a third implement drive speed. The first and second shift points are based on loading of the implement during operation. In addition, the first and second shift points are different.

摘要： Embodiments in this disclosure include a cutting tool mounting block that is securely mounted to the periphery of a wheel. The mounting block includes a body portion with a channel having a width that expands along the length of the body portion. The cutting tool mounting block also includes an aperture configured to accept a single cutting tooth, in some embodiments. The cutting tool mounting block may also include a front feature that creates a clearance between the cutting tooth surface and the body portion. Some embodiments include the assembly of three mounting blocks on a stump grinder wheel, which can increases the bite each tooth takes, it can decrease the drag in the cutting wheel, and it can decrease chip recirculation.

摘要： A stump cutting assembly mounted to a stump cutting wheel. Stump cutting assembly is a stump cutting tooth interconnected to the wheel by a holder or block that is fixed to wheel by welding or other equivalent process, an optional debris deflector and a fastener that interconnects tooth and deflector to holder. As wheel rotates about its axis of rotation, the tooth cuts away at wood or other debris in which it comes into contact through the side to side and/or longitudinal movement of a stump grinder unit.

摘要： A stump grinder is configured to mount to a portable machine that operably supports the stump grinder during a stump grinding procedure. The stump grinder includes a cutting wheel that is rotatably driven during the stump grinding procedure. The cutting wheel has a cutting surface to grind the stump by moving the rotating cutting wheel across the stump. A wheel stabilizing assembly is disposed between the portable machine and the drive system for supporting the drive system and cutting wheel. The cutting wheel is held in a generally vertical orientation and movement of the cutting wheel is biased relative to the portable machine. Accordingly, forces applied against the cutting surface of the cutting wheel during the grinding procedure are limited by the biased movement.
