    Abstract: The bedding groomer comprises a frame attachable to an ag vehicle such as a skid loader or tractor for movement down the alley of a free stall barn. Pivotally supported on the frame is an elongate shroud that can be moved from a raised travel position to a lowered, laterally extending working position by a hydraulic cylinder. Rotatably mounted within the shroud is an elongated arbor driven by a hydraulic motor. Along the length of the arbor is a plurality of radially projecting tines. As the ag vehicle travels down the alley, the tines dig into the animal bedding material, churning it, to break up hard packed and compressed areas and to aerate deep within the bedding to aid in aerobic composting any organic material, such as manure, that is present in the bedding.

  • Patent number: 4938537
    Abstract: An end closure for the cutter housing of a road planer in which a pair of self-opening and self-closing cover plates provide a protective cover over a shaft clearance opening in the end wall of the housing. The cover plates, pivotally mounted on an external wall surface of the housing, move between a closed position at which the cover plates cooperatively overlay the shaft clearance opening, and an open position at which clearance is provided for a rotatable shaft extending through the housing end wall, in response to moving the end wall vertically with respect to the frame on which the cutter is rotatably mounted.

  • Patent number: 4775014
    Abstract: A ground-working implement for rotary field tilling or ice or snow-tending n ski slopes or the like which is drawn by a tractor or a tracked vehicle and which comprises a holder connected to the vehicle pendulously by a longitudinal beam which can be raised and lowered. The holder is connected to a rotary ground-loosening unit and a smoothing board by a four-point linkage whose cranks are dimensioned so that upon raising of the ground-loosening unit the orientation of the smoothing board remains largely unaltered thereby allowing the latter to be used for leveling the ground when the ground-loosening unit is in its raised or rest position.

  • Patent number: 4669549
    Abstract: A tiller cover assembly covering a rotary tiller unit is provided inside thereof with rake members arranged at a spacing along the width of cultivation for sieving lumps or blocks of soil carried around by the tiller unit. Each of the raker members is made of a resilient rod which has a coiled portion toward its base end and is fixed to an attaching member at the base end above the coiled portion. The coiled portions of the rake members are projected toward an upwardly or downwardly movable rear cover of the cover assembly, permitting the rear cover to contact the coiled portions. A clearance is formed between sieving portions of the rake members extending downward from the coiled portions to their free ends and the rear cover. A protector is provided on the inner side of the coiled portions, by which the lumps or blocks of soil carried around by the tiller unit are prevented from striking the coiled portions.

  • Patent number: 4586444
    Abstract: Liquid applications of materials such as herbicides usually are broadcast over the field and then incorporated by harrowing or the like. The present device utilizes a plurality of open based boxes having a rotary cultivator therein with a spray nozzle attached to a supply of liquid chemical under pressure thus restricting the application of the chemical to a band the width of the box and incorporating it at the same time. Rake teeth smooth out the soil behind each applicator and a seeding or planting machine may be hitched behind the incorporator followed by a packer so that the entire chemical treatment, incorporation thereof, planting and packing can be undertaken in one pass over the field.
