Abstract
An apparatus for withdrawing compressed fodder or similar agricultural material from a pile has an engaging tool which is mounted on a cantilever arm arrangement. This arrangement is capable of reaching over a quantity of fodder to be withdrawn and engaging behind the quantity from above so that the remainder of the material will not be loosened. The engaging tool shifts the quantity of fodder into a receptacle which is mounted on a common support with the cantilever arm arrangement, the support being adapted to be mounted on a tractor. Hydraulic cylinder-and-piston units connected to the hydraulic system of the tractor are used for moving the engaging tool into and from the receptacle.
