Abstract: A carrier for cylindrical hay bales is described which is adapted for mounting on the box of a pickup truck. It includes a shaft pivoted in a support frame about a horizontal axis and a pair of bale lifting arms are mounted to opposite ends of the pivoted shaft. These arms can swing laterally for engaging and disengaging hay bales by means of bale piercing spikes at the outer ends of the arms. A hydraulic system is provided for swinging the pivoted shaft and bale lifting arms from a rearward position adjacent the ground to a forward position adjacent the truck body. For this purpose, two hydraulic cylinders with a special crank arm linkage are used with one of the hydraulic cylinders being capable of swinging the bale lifting arms through an arc of up to about 130°C and the second hydraulic cylinder being adapted to swing the bale lifting arms through an additional arc of up to about 70°C. This provides exceptional versatility in the handling of the bales.
