ABSTRACT:
In a rammer powered by an internal combustion engine, the engine is placed on a side of an upper part of a rammer main body with its crankshaft extending in parallel with the handle bar of the rammer, and the cylinder axis of the engine slanted sideways so that the overall height of the rammer may be controlled even when a relatively large engine is employed. The engine is mounted on the rammer main body so that the center of gravity of the engine is on the axial center line of the rammer main body as projected on a plane perpendicular to the crankshaft. Therefore, a relatively large engine can be used without destroying the balance of the rammer, and the rammer, therefore, would not produce any tendency to tilt during use. Thus, the rammer is easy and comfortable to handle even when a relatively large engine is mounted thereof.
