  • Patent number: 4290733
    Abstract: A forage stack moving device has a tongue and bed mechanism rigidly secured to each other in which a plurality of endless chain elements pass over a plurality of longitudinal beam members and are driven by a mechanism driving all chains in unison while loading and unloading a stack. The bed mechanism is supported by a pair of fourbar linkages, each having a pair of substantially vertically extending arms pivotally joined to a longitudinally extending carriage member to which are secured a pair of wheels, each longitudinally extending member having a hydraulically controlled extensible member connected to the bed mechanism to move the carriage member and the wheels secured thereto, causing the bed mechanism to tilt for loading and unloading and to be substantially level during transportation of any forage stack on the bed mechanism.
