Patent number: 6951253Abstract: A grooming apparatus, for sloping, aerating and fluffing bedding material in livestock free stalls, is attached to a vehicle such as a skid steer. The grooming apparatus includes a rotary arm, having grooming members, and connected to the vehicle by a boom. The rotary arm, when viewed across the stalls, is angled at a slope. The grooming members contact the bedding material to fluff and aerate it, and arrange it according to the slope. The rotary arm, when viewed from the end of a stall, may be pitched forward or rearward. These pitches and angles permit the grooming members to more effectively move the bedding material within each stall to create the slope. Such a slope is beneficial for livestock that prefers a sloped bed. Using the boom, the rotary arm can be moved up and/or out of the way when the vehicle is moved through doorways and the like.Type: GrantFiled: March 16, 2004Date of Patent: October 4, 2005Assignee: Superior Attachments, Inc.Inventor: Richard Linsmeier

Patent number: 4293042Abstract: An oscillating harrow having a pair of harrow rings which can be raised and folded easily for transport. Each ring includes a pair of opposed, central segments which are disposed below a ground-travelling frame, and a pair of opposed side segments which are mounted on the central segments for swinging between positions extending laterally and upwardly with respect to the frame. A pair of wing members attached to opposed sides of the frame, adjacent opposed side segments, are shiftable between operative and transport positions. The wing members are coupled to associated side segments through cables which are slack when the members are in their operative positions. As the wing members are swung from their operative to their transport positions, slack in the cables is taken up, causing the side segments to be drawn toward the associated wing members.Type: GrantFiled: January 21, 1980Date of Patent: October 6, 1981Inventor: August M. Reuber

Patent number: 4250969Abstract: A cultivating attachment mounted on a tractor is driven by the power take-off drive of the tractor to simulate the customary action of a hoe when it is manually manipulated. The desired effect is achieved by providing a pair of ground engaging rotatable cutting elements at the ends of an arm mounted on a chassis which is connected to the tractor frame. Shafts are connected to the ends of the arm and also eccentrically connected to plates which are rotated by a drive connected to the power take-off of the tractor. Movement of the eccentrics imparts an oscillating and vertical movement to the arm and the cutting elements connected thereto as the cutting elements engage the ground being cultivated.Type: GrantFiled: October 2, 1979Date of Patent: February 17, 1981Inventor: Pedro Orlanda

Patent number: 3949813Abstract: A soil cultivator has a beamed frame with a coupling member to be attached to a tractor. A plurality of rotatable tined soil working members are mounted in a row that extends transverse to the direction of travel. The soil working members are power driven by driving means to rotate about upwardly extending axes and work overlapping strips of ground. The action of the tines breaks up soil, even heavy soil, and a roller is connected to trail the soil working members. The roller has annular plates the outer peripheries of which are formed by horizontally extending elongated elements that engage and smooth the ground behind the tines. The roller is adjustably pivoted to the frame by arms to support the weight of the cultivator. By moving the arms about pivots, the working depths of the tines and the amount of weight borne by the roller can each be regulated to a significant extent.Type: GrantFiled: August 5, 1974Date of Patent: April 13, 1976Inventor: Cornelis van der Lely
