    Abstract: A snow pusher attachment for use in conjunction with a straight blade angle-type snow plow mounted to a work vehicle. This pusher allows a work vehicle to capture, contain, and relocate large amounts of snow very quickly and efficiently. The attachment consists of side panels, connected by horizontal members between. This pusher attachment is secured to the snow plow by bracket assemblies, attached to the upper edge of the snow plow that engage hooks on the upper, rear portion of the pusher attachment. The attachment does not require the operator to exit the work vehicle to secure or release it from the snowplow. Accordingly, the attachment allows the quick and repeated conversion of a snow plow into a snow pusher box and visa versa.

Each of the front surfaces of the central front portion, the interposition front portions, and the side front portions is formed in an arc-shaped surface that has a prescribed radius R2. The radius R2 satisfies the following formula: R2=(0.7 to 1.0)×H, where H is the height from the edge of the first edge section to the top end of a soil retaining plate in side view in a digging posture when the edge angle ? of the edge sections is an angle of 40° to 55°.

  • Patent number: 7654016
    Abstract: A snow pusher attachment for use in conjunction with a straight blade angle-type snow plow mounted to a work vehicle is disclosed. The attachment consists of side panels, connected by horizontal members. The pusher attachment is secured to the snow plow by bracket assemblies, attached to the upper edge of the snow plow that engage hooks on the upper, rear portion of the pusher attachment. The pusher can be secured or released from the snowplow by manipulation of the plow blade allowing quick and repeated conversion of a snow plow into a snow pusher box and visa versa.

  • Publication number: 20090320332
    Abstract: The present invention lies in the field of clearing bars (3) for the clearing blade (1) of a snow plough, which clearing bars are defined at least partially in cross section by a curved contour (10). They are based on the object of avoiding undesirable swirling of snow within the clearing blade (1). The invention is based on the finding that the snow is swirled on parts (7) of the fastening means (5) for fastening the clearing bar (3) to the clearing blade (1). To solve this problem, a design of the contour (10) that is optimized dynamically in terms of flow is described.

  • Publication number: 20090307941
    Abstract: A plow, including a center blade and a wing blade coupled to each end of the center blade. Each wing blade is pivotally connected to the center blade about an axis. The plow includes a first pair of wear strips, with one wear strip coupled to the first end of the center blade and the other wear strip coupled to one wing blade. A second pair of wear strips is included, with one wear strip coupled to the second end of the center blade and the other wear strip coupled to the other wing blade. A wing pivot tube is coupled to the wing blades and center blade at each end of the center blade. The wing blade, wear strips, and wing pivot tube at each end of the center blade minimize a gap between the blades throughout the range of movement of each wing blade.

  • Patent number: 7596892
    Abstract: A blade (3) meant to work in the curved form of a snow plough and attached from its lower edge to a rigid beam, the upper edge of which is supported by means of upper beam (12) or similar, and said blade is of flexible material, as plastic sheet. The blade is from its upper beam (12), essentially from its middle, supported by suspension means (9), which due to the ploughing load allows upper beam (12) and blade (3) upper edge to tilt and blade (3) to change the radius of curvature at least from the suspension spot on the blade area toward the blade point.
