  • Patent number: 3993413
    Abstract: A pneumatic tire-type compacter is mounted to be towed behind a road maintainer to pack the road immediately after it is graded. A single hydraulic cylinder raises the packer unit for maneuvering the grader; also, the hydraulic cylinder provides means for transferring weight from the maintainer onto the packer. Links between the maintainer and compacter provide proper operation. A small moldboard is attached to the compacter in front of the compacter to handle the dirt rolled from the maintainer.
