摘要： An agricultural row unit for use with a towing frame hitched to a tractor includes an attachment frame adapted to be rigidly connected to the towing frame, a linkage pivotably coupled to the attachment frame, and a row unit frame having a leading end pivotably coupled to the linkage to permit vertical pivoting movement of the row unit frame relative to the attachment frame. A hydraulic cylinder coupled to the attachment frame and the linkage, for urging the row unit frame downwardly toward the soil, includes a movable ram extending into the cylinder, and a hydraulic-fluid cavity within the cylinder for receiving pressurized hydraulic fluid for advancing the ram in a direction that pivots the linkage and the row unit frame downwardly toward the soil. An accumulator positioned adjacent to the hydraulic cylinder has a fluid chamber containing a diaphragm, with the portion of the chamber on one side of the diaphragm being connected to the hydraulic-fluid cavity in the hydraulic cylinder, and the portion of the chamber on the other side of the diaphragm containing a pressurized gas.

摘要： A cultivating disc for a tillage implement includes an attachment portion positioned at a radial center of the cultivating disc. The attachment portion includes one or more attachment features configured to couple the cultivating disc to the tillage implement about an axis of rotation of the cultivating disc. The attachment portion extends along a first plane perpendicular to the axis of rotation of the cultivating disc. The cultivating disc also includes a cutting edge portion positioned at a distal end of the cultivating disc relative to the axis of rotation. The cutting edge portion extends along a second plane parallel to the first plane. The cultivating disc further includes a curved connecting portion positioned between and connecting the attachment portion to the cutting edge portion. The curved connecting portion further defines one or more radii of curvature.

摘要： A land clearing attachment for a tractor device includes semi-helically oriented teeth, knives, or blades radially outward from an outer surface of a rotor. Each tooth, knife, or blade is part of a row of teeth, knives, or blades. Each row is oriented with an offset angle such that the spirally orientation completes angular offset of about 90° or less.

摘要： A land clearing attachment for a tractor device includes semi-helically oriented teeth, knives, or blades radially outward from an outer surface of a rotor. Each tooth, knife, or blade is part of a row of independent teeth, knives, or blades. Each row is oriented with an offset angle such that the spirally orientation completes angular offset of about 90° or less.

摘要： An earth cutting apparatus comprising a plurality of articulated elements including at least a first element having a mounting structure thereon and an adjacent second element hingedly connected to the first element. An earth cutting member is provided including a proximal end which is pivotally mounted to the mounting structure of the first element and an earth cutting end. The earth cutting member is slidably connected to the adjacent second element and moveable between an extended position and a retracted position, such that hinged movement of the adjacent second element relative to the first element causes the earth cutting member to slidably extend from the adjacent second element to the extended position for operatively cutting earth. Hinged movement of the adjacent second element in an opposite direction causes the earth cutting member to slidably retract to the retracted position.

摘要： 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.

摘要： A powered hand tool is adapted to use a variety of interchangeable rotary tools to assist in outdoor activities. Either of two basic tool designs can be utilized for activities including garden tilling, brushing and cleaning, auguring or post hole digging, and auto finishing and polishing. In one embodiment, an adjustable shroud is utilized along with a tiller construction to change the viewing angle of the working tiller tines to facilitate use by operators of different heights, including a kneeling position. The ability to utilize tow torque and low speed assists in avoiding accidental damage to underground wires and, if encountered, the reversibility of the drive assists in untangling the wires.
