  • Patent number: 6209236
    Abstract: A rock picker and material loader attachment is pivotally mounted to a loader scoop or bucket and extends longitudinally forward therefrom. A plurality of teeth form the leading surface of the attachment during digging and loading operations. Parallel, relatively planar plates form the structural support for the plurality of teeth, will simultaneously acting as a debris catcher and allowing an operator to view the teeth while engaging material through the debris catcher. An adjustable support is used in combination with a small, easy-to-use wedge, to control and adjust the characteristics of rotation of the attachment relative to a scoop or bucket. A two speed hydraulic cylinder may also be used as the primary mover to effect the rotation of the attachment. The attachment is useful for rocks, manure, trash, bales and other materials.

  • Patent number: 5664348
    Abstract: A rock picker and material loader attachment is pivotally mounted to a loader scoop or bucket and extends longitudinally forward therefrom. A plurality of teeth form the leading surface of the attachment during digging and loading operations. Also adjacent the bucket and support bar is a laterally extending debris catcher. During picking and scraping operations, the debris catcher is perpendicular to the bottom of the bucket, extending up from the bottom and thereby acting as a block or retaining plate which assists in retaining debris in the bucket. Two longitudinal knees form a quarter-circle are at or near the longitudinal position of the mounting between the attachment and the bucket. During loading from the inventive attachment to the bucket, the knees are used to pivot the attachment and allow material or debris to roll into the bucket. While the attachment is pivoting, the debris catcher assists by moving any debris near the edge of the bucket back and away therefrom.

  • Patent number: 5340038
    Abstract: A material reduction apparatus has a material loading bin for receiving material to be reduced. Below the bin is located a plurality of substantially parallel cutter bars with opposing ends and cutting tips thereon. The cutter bars are supported below the bin. Crank means are pivotally connected to at least one end of each cutter bar for alternatingly moving each cutter bar upward and downward as well as parallel in line left to right unlike the movement of the adjacent cutter bar for kicking, tossing and cutting the material to be reduced.
