ABSTRACT:
A backfiller and tamper unit (10) is disclosed which is a self contained unit that acts to both backfill and compact soil into a trench for complete restoration. The unit includes a tractor (12) which mounts a vibrator and tamping wheel assembly (14) and a backfill auger assembly (16). The vibrator and tamping wheel assembly (14) is mounted on a mast (50) which is pivotally secured to the tractor for limited arcuate motion from vertical. This permits the mast to be tilted so that the compaction force of the vibrator and tamping wheel assembly is most effectively directed to compact the soil in the trench. The vibrator and tamping wheel assembly is free floating on the mast which isolates the tractor from vibration generated by the vibrator and tamping wheel assembly and provides greater compaction efficiency. Further, the vibrator and tamping wheel assembly can be lifted vertically on the mast by a lift mechanism (62) for storage.
