Abstract
A machine (100) includes a frame (102) portion and a tandem wheel arrangement, which includes a main linkage (312) and a stabilizing linkage (322) that are pivotally connected to the frame (102) portion. A first mount (304) and a second mount (304) are pivotally connected to the main linkage (312) and to the stabilizing linkage (322), such that the main linkage (312), the stabilizing linkage (322), the first mount (304), and the second mount (304) define a four-bar-linkage arrangement (202) that operates to transfer unbalanced torque loads from the first mount (304) and the second mount (304) to the frame (102) portion.
