Abstract
A wheel mounted chassis is provided with a pair of spaced and parallel conveyor chains extending longitudinally from the front to the rear of the chassis. A pair of cylindrical bale, pick-up arms are pivoted forwardly of the chassis and are adapted to be engaged with each end of a bale to be picked up. Fluid operator means pivot the arms and the bale through an arc and deposit the bale onto the conveyor chains. The arms then return to the forward position to pick up the next bale. As the arms move rearwardly through an arc, means are operatively connected to the conveyor chains to move the upper runs thereof rearwardly a predetermined amount and stop clutch or ratchet means prevent forward movement of the upper runs of the conveyor chains when the arms move forwardly. The first bale is thus moved rearwardly as the next bale is picked up and deposited and this continues until the chassis is full or enough bales are loaded thereon. A stop device at the rear of the chassis retains the bales until it is desired to dump them whereupon the stop device is lowered and the arms are actuated thus moving the bales rearwardly until they roll off the rear end of the chassis. A hitch enables the…
