Abstract
A vehicle such as a combine harvester or the like includes a main frame, a track roller frame pivotally connected to the main frame, a drive wheel including a hydraulic drive motor having a housing and a rotatable shaft assembly, and an equalizer bar connected in a first embodiment to the shaft assembly by a coupling device including an anti-friction bearing and a trunnion member having a pair of pivot pins arranged along a substantially horizontal and longitudinally extending axis. In a second embodiment the equalizer bar is connected to the housing by another coupling device including a trunnion member having a pair of similarly oriented pivot pins. In each instance the transversely oriented equalizer bar is arranged along the transversely oriented central axis of the drive wheel, which provides a very stable 3-point frame suspension that is also rugged and economical and has a minimal tendency to collect mud or debris on the upper surfaces thereof in use.
