  • Patent number: 7805862
    Abstract: A float mechanism for attaching a material-moving implement to an instant transfer connector has a pair of spaced apart substantially vertical supports, each with a substantially vertical slot in an upper region and configured to attach to the instant transfer connector. The slots are slidably engaged by a transfer bar attached to the implement, and a stabilizing structure limits the motion of the transfer bar in the slots. The limited flexibility allows the implement to push material across uneven terrain. Blocks can be employed to disable the flexible action when the implement is employed for loading and dumping material.

  • Patent number: 7360327
    Abstract: A pusher/bucket has back plate with wings pivotably mounted at either end, and a drop blade pivotably mounted thereto. The drop blade can be secured in a raised position where it is superimposed over the back plate; when in the raised position, the wings can be positioned relative to the back plate to provide a wing plow. The wings can be folded parallel to the back plate, with the raised drop blade residing therebetween. When the wings are normal to the back plate, the drop blade can be secured in a lowered, horizontal position; in this position, the drop blade acts as the bottom of a loading bucket, the sides being formed by the wings and the back plate. A float mechanism allows the pusher/bucket to push material across uneven terrain, and is preferably disabled when the pusher/bucket is configured as a bucket for loading and dumping material.
