Abstract: A method and a device are provided to compress crop material laid down in single layers for producing silage in a horizontal silo, with the use of an agricultural working machine, that carries a compressing device, the crop material laid down in single layers is compressed by at least one compressing element, and the at least one compressing element weighs on the crop material and moves relative to it.

Abstract: A system for storage of green fodder and the like includes a cylindrical storage tank removably carried on a trailer which can be towed by a tractor. The frame of the trailer carries a tiltable platform having a rotatable plate on which the tank rests. The frame also carries a vertically movable apparatus for supporting either compaction rollers insertable into the tank top for compressing fodder as it is conveyed into the tank, or an elevator mechanism for lifting the tank away from its bottom cover to expose compacted fodder for removal. The tank is rotated during loading/compaction and removal. Compression of the fodder greatly increases the amount of fodder storable in each tank. After filling the platform is tilted, the tank is removed and can be rolled to a storage location with its axis horizontal.

Abstract: A hay stacking machine having a platform for supporting a stack of hay. The platform has a trough extended from its center to the outer peripheral edge for accommodating hay. A hay feeding mechanism having reciprocating teeth operates to move hay from the outer edge of the platform generally toward the center thereof. One embodiment of the machine has a movable elevator member located in the center of the platform operable to move hay upwardly to build the center of the stack. An annular cage extends around the platform and rotates relative thereto. The cage has a plurality of upright posts carrying compression arms which extend toward the center of the platform. The pressure arms move with the cage and engage the hay located on the platform to sweep it along the platform top surface causing a stack of hay to form from the bottom up. The unloading of the hay stack from the platform is accomplished by opening gate sections of the cage and tipping the platform rearwardly and downwardly.
