Abstract

A multiple use agricultural vehicle is disclosed for collecting and transporting a plurality of hay bales at different levels which includes an auxiliary structure for lifting and transporting livestock. The vehicle includes an elongated mobile frame having laterally spaced side members with upper and lower lifting and supporting members movably mounted thereon and arranged in longitudinally spaced and laterally opposed nesting units. The vehicle includes separate motors for selectively moving the upper lifting and supporting unit between a lowered nested position and a raised load supporting position, and sequentially raising the lower lifting and supporting unit to a load supporting position, or raising the nested upper and lower units simultaneously to a load supporting position. A goose-neck tongue member is pivotally connected at the forward end of the frame to permit pulling of the vehicle by a prime mover in longitudinal alignment and in laterally offset relation.
