A work machine includes a motive portion, a work portion driven by the motive portion, a discharge path for discharging a work object obtained as a result of the work portion rotating, and a control portion for controlling the motive portion. The control portion includes a detection portion for detecting that the discharge path is clogged with the work object, and a work control portion for, upon the detection portion detecting that the discharge path is clogged with the work object, controlling the work portion and performing an elimination operation for eliminating the clogging with the work object in the discharge path.

A snow removal device features a pushing element and handle. The pushing element has a main portion defining an upright plane with opposing front and rear surfaces and a bottom edge along the front surface. Laterally opposing end portions of the pushing element extend forwardly from the upright plane and have bottom edges. The bottom edges of the end portions adjacent the front surface are acute relative thereto so that the main portion is pivotal about its bottom edge from a normal working orientation in which the upright plane is substantially perpendicular to a flat surface along which the pushing element slides to a forward inclined orientation which is pivotally further forward of the normal working orientation without lifting the bottom edge of the main portion. The device further features a scraping flange extending rearwardly and downwardly from the rear surface.

A snow-plow blade having a blade, an insert, and a cover-plate, with the cover-plate having a crenellated structure and abrasion resistant steel, the structure extending the service life of the snow-plow blade and improving snow-plow blade maintenance servicing.

A front-mounted clamshell scoop or shovel arrangement mounts onto the snowplow mounting bracket of the frame of a snowplow assembly when the blade has been removed. The scoop can be closed and lowered to scoop and pick up work-site debris or other materials, raised so the materials can be transported to a collection site, and the jaw portion is rocked to an open position to allow the material to drop from the clamshell scoop. In controls for the snowplow assembly serve to raise and lower the scoop and to open and close it.

A Variable Geometry Bucket for material handling, such as plowing snow. The Variable Geometry Bucket generally includes four bucket members pivotally attached to each other. A pair of double-acting hydraulic cylinders can cause the outer bucket members to rotate on a frame, which in turn moves the inner bucket members. Due to the location of the pivotal connections, the bucket members can be moved into different positions, resulting in a single attachment that can be used as a V-blade, a box plow, and a bucket.

A connector for securing a snow plow blade to a supporting structure such as a moldboard, especially a connector that can quickly connect and disconnect the blade to the support structure.

A blade for a work machine includes a body having a main portion including a top edge, a bottom edge, a first lateral edge and a second lateral edge. A wing portion is pivotally coupled to the body about a pivot axis. The first lateral edge includes a curved edge extending outwardly towards the wing portion, where the curved edge forms an apex between the top edge and the bottom edge. A first axis is defined through a first intersection point and a second intersection point, the first intersection point located at an intersection of the top edge and the first lateral edge and the second intersection point located at an intersection of the bottom edge and the first lateral edge. A second axis is defined through the apex and is parallel to the first axis. The pivot axis is located between the first axis and the second axis.

An exemplary plow includes a moldboard having a wear surface and a blade having a wear surface. A wear resistant coating is applied to at least a portion of at least one of the wear surfaces of the blade and moldboard. The wear resistant coating includes a plurality of scales. Each scale has a leading edge, a trailing edge, a raised portion disposed between the leading edge and the trailing edge, and a peak of the raised portion disposed closer to the trailing edge than the leading edge. The scales of the wear resistant coating are arranged in a plurality of rows, and gaps formed between scales in one row are offset from gaps formed between scales in an adjacent row.

A system of actively introducing opposite phase vibrations to reduce or cancel vibrations caused by operating a snow plow. The invention also relates to a method of actively introducing such opposite phase vibrations.

A dozing blade assembly includes a dozing blade and a multi-piece cutter mounted to the dozing blade and including an elongate body having a first outer body piece and a second outer body piece that are mirror images of one another, and each including an inboard stem having a linear leading edge profile, and an integral outboard end bit having a curvilinear leading edge profile. The outer body pieces are structured for mounting to the dozing blade such that digging faces of the outer body pieces are oriented at a shallower angle than digging faces of the middle body piece, relative to a horizontal plane.
