a linkage arrangement is disclosed to provide an articulated machine with an arrangement that allows two frame structures to both articulate and oscillate relative to one another . the linkage arrangement includes a three point pivot arrangement with an angled link . two of the pivots provide for articulation while two of the pivots provide for oscillation . the two pivots involved for oscillation are of lower overall height than the overall height for the two pivots providing the articulation , thereby reducing overall machine height while maintaining structural integrity .
