Patent number: 5725057Abstract: A device for crushing stubble comprising a rotatable crushing element supported by a frame. The frame is coupled by a pivotable connection to a drive mechanism which moves the device in a predefined direction across the stubble. The pivotable connection allows the crushing element to pivot about an axis substantially parallel to the predefined direction of motion so that substantial contact is maintained with the ground, thereby maximizing the extent of crushing. Limited vertical movement of the crushing element is permitted by a suspension mechanism.Type: GrantFiled: May 30, 1995Date of Patent: March 10, 1998Inventor: Kenneth Noel Taylor

Patent number: 5353881Abstract: A gardening utility machine having a counter-rotation twin shaft system can perform multiple types of work required for gardening (tilling, soil removal, weeding, raking and shredding of leaves), snow/ice removal and for power de-thatching and mowing of lawn grass. This can be done by exchanging attachments on the counter-rotating twin shafts: if tines are installed on the twin shafts, soil tilling, weeding can be done; if auger blades with or without digging bits are in place instead, the machine can simultaneously till and remove soil or can remove ice/snow, or rake and shred leaves; if the front shaft is installed with a spiked roller and the rear shaft, a shearing reel, then the machine can power de-thatch and mow grass at the same time, and additional grass clipping mulching ability can be performed if a fan blower equipped with a mulching fan blade and a retractable bedknife is in place.Type: GrantFiled: July 6, 1993Date of Patent: October 11, 1994Inventors: Kai S. Lee, Esther W. Lee

Patent number: 4260027Abstract: A rotatable flail-type agricultural implement is disclosed which includes a central axle and a plurality of radially and circumferentially spaced, flexible, hammer-supporting chains presenting a plurality of ground crop-engaging flails upon rotation of the axle. The axle is preferably composed of a pair of elongated, telescopically interfitted sections, at least one of which is shiftable, such that the effective width of the implement can be varied to accommodate different crop row spacings. In addition, the axle sections include complemental, spiral key and keyway structure for maintaining the flexible hammer chains in a substantially constant, spaced relationship to the central axle, irrespective of variances in the axle length.Type: GrantFiled: April 17, 1978Date of Patent: April 7, 1981Assignee: W.E.F.C.O., Inc.Inventor: Ervin C. Langan

Patent number: 4044841Abstract: A device in the nature of a rotary tiller equipped for traveling through fields as well as uneven terrain, for effectively chopping up encountered clods, vegetation and debris, and mixing same with the soil. We utilize a framework in which either of two different types of bladed, couner-rotating rotors may be effectively mounted, with one type of rotor having a number of outwardly extending teeth that are adapted for penetrating the ground as the tiller device moves thereover. The outermost portion of each tooth is provided with a novel cutting blade, which may interact with a stationary shear bar, with this type of blade being well adapted for chopping up encountered vegetation and for mixing it thoroughly with the soil.Type: GrantFiled: June 27, 1975Date of Patent: August 30, 1977Assignee: Smitty's IncorporatedInventors: Alexander Smith, Burton D.

Patent number: 3957122Abstract: A rotary plough has one or more rotors rotatably mounted to be driven via a power take off about a horizontal axis that extends transverse to the direction of travel. Each rotor has a central support and axis of rotation and two spaced apart and oppositely positioned rotatable soil working members, each of which has a soil working support with two rows of tines. A driving connection is established between a P. T. O. and a shaft within the central support which turns each soil working member through a control mechanism. The control mechanism can be a pinion gear arrangement or a chain and sproket combination that turns the tine supports of the soil working members so that a transmission ratio is established to cause the tines to rotate more or less about their supports while also turning about the central support. Earth lumps are cut and lifted by the tines and then moved to an inverted position back to the dug out cavity.Type: GrantFiled: March 4, 1974Date of Patent: May 18, 1976Inventor: Cornelis van der Lely
