Abstract
A soil compacting percussion rammer includes an operator handle assembly that is isolated from the main machine frame by a shock absorbing mount oriented to absorb the horizontal components of operating movement of the rammer. In a preferred embodiment, the shock absorbing mount comprises a pair of torsionally resilient shock absorbers interconnecting the frame and the operator handle and oriented to position the shock absorbers on a common torsional axis that is vertically offset from and generally parallel to the horizontal operator handle.
