Abstract
A ramming device for compacting soil includes an upper mass and a lower mass. The lower mass is driven linearly back and forth with respect to the upper mass to compact material therebelow. An engine drives the lower mass and is supported by the upper mass. A muffler is fluidly connected to the engine and is contoured such that a majority of the muffler is positioned inboard of a footprint of a side of the ramming device. Preferably, the muffler has a shape that substantially matches a shape of the upper mass adjacent to the muffler thereby further reducing the distance that the muffler extends beyond a footprint of a sidewall of the device.
