Abstract: A particulate material product cart uses a transfer mechanism for unloading particulate material from the cart. The cart includes a frame supporting an inlet hopper and a discharge chute thereon. The transfer mechanism includes a drum forming a plurality of radially divided product chambers. An inlet opening communicates between one of the product chambers and the inlet hopper and an outlet opening communicates between one of the product chambers and the discharge chute. Rotation of the drum transfers particulate material from the inlet hopper to the discharge chute with minimal disturbance of the product. The cart is particularly suited for handling pulse crops that require gentle handling to avoid crushing, for example beans, peas, lentils and the like.
