ABSTRACT:
In a preferred embodiment of the invention a pair of shock plates are disposed in parallel, and substantially bi-planar, coupled together by elastomeric elements. One of the shock plates has a cut-out therein and the other has a limb extending into the cut-out and spaced apart from the sides thereof. The one shock plate is mounted to the drum bearing housing of the earth compactor, and the other shock plate is mounted to the frame. Accordingly, upon the drum being vibrated, or shocked, or otherwise displaced, the limb engages one or more sides of the cut-out, and the movement between the plates is thereby limited to a given distance, in order that the elastomeric coupling will not be unduly stretched, destroyed, or fatigued too early.
