A system for shaking a beater rod means of a harvester comprises a beater rod drive means which shakes the beater rod assembly and a drive compensating means. The drive compensating means includes a first counterbalancing weight means and a second counterbalancing weight means in a drive transmission to cause the first and second weight means to rotate in a manner so that when the first weight means is rotating from a bottom location to a top location the second weight means is at the same time moving from its bottom location to its top location and also in a manner that when both the first and second weight means are moving from their bottom to their top location, they have lateral components of motion which are opposite to one another thereby imparting vertical inertia force components to counteract the up and clown motion of the beater rod assembly, while lateral force components of the first and second weight means cancel each other out.
