Abstract
A narrow self-propelled trench soil compactor has a vibratory frame assembly connected in a towing relation to a mobile frame having steerable front wheels. The vibratory frame assembly is pivotally connected to the mobile frame for vibratory up and down movement independently of the mobile frame. A soil compaction wheel is rotatably supported at the free end of the frame assembly for movement to a lowered operating position and is power driven to function as the propulsion means for the machine. When the compaction wheel is in an elevated or non-operating position, the machine is attachable to a towing tractor for transportation purposes.
