An earth compacting apparatus for mounting at one end of an earth working vehicle comprises a plurality of separate compaction units and a pivotal linkage for pivotally mounting the compaction units side by side on a vehicle. An actuator assembly operates on the linkage for independently raising and lowering each compaction unit between a raised, inoperative position and a lowered position in contact with the ground. The actuator assembly also provides downward pressure on each compaction unit in the lowered position.
