A pusher/bucket has back plate with wings pivotably mounted at either end, a nd 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.
