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.

The Row Digger provides a tool that enables an operator of the Row Digger to remove dirt piles interfering with irrigation between crop field furrows and irrigation trenches. The Row Digger includes a frame capable of moving from a transportation position to an operation position. The Row Digger also includes a plurality of digger arms extending from a central hub and each terminating in a corresponding digging disc. The central hub is connected to the frame at a hub angle and is capable of rotation about a hub axis. Each digging disc is also connected to the corresponding digger arm at a disc angle. Each digging disc enters a crop furrow and utilizes the slopes of the ridges to create the rotation required about the hub axis and ensure a path of travel for the digging discs that removes the impeding dirt piles.

A tillage tool achieves stability at higher speed ranges by providing stabilization with additional damping through damping elements on the front support wheels and on the constant level linkage and on the rear tool. The tillage tool maintains maximally one longitudinally positioned unsuspended load path to the ground provided by unsuspended depth gauging wheels longitudinally positioned parallel to a front to rear rocking axis to allow for constant settings throughout the depth, speed, and field condition ranges.

It is an object to secure a state where an operator easily reaches various operating means with a hand, and to reliably maintain an original function of an arm rest (to put the hand on the arm for rest). A working vehicle is configured such that speed of power from an engine provided in a traveling machine body is changed by a hydraulic continuously variable transmission, and the power is transmitted to a traveling unit and a working unit. An arm rest on which the operator's arm and hand are put is placed on a side of a cockpit in the traveling machine body. A main transmission lever which changes traveling speed by the traveling unit is arranged on a front end of the arm rest on the side of the cockpit. An elevating dial which hoists and lowers the working unit is arranged on a side surface of the arm rest on the opposite side from the cockpit.

A rear module, as illustrated with tanks, seed blowers, and transfer pump for fertilizer is mounted on the existing design frame, axle, and steering system; but it is a separate, distinct module. The planting module and the harvesting module must be disconnected from the common front module power unit and switched for planting row crops or harvesting. The harvesting configuration can have an attachment to the header to seed non row crops, such as, a cover crop like rye or canola Such rear module can be the rear unit of an articulated vehicle, such as a harvester.

A tillage implement may include at least one electric motor coupled to a ground engaging tool, a power storage component configured to store power and to provide the power to the at least one electric motor, and a controller communicatively coupled to the at least one electric motor and the power storage component. The controller comprises a memory and a processor and the controller may provide instructions to the at least one electric motor to adjust a rotational speed of the ground engaging tool, an angle of the ground engaging tool relative to a soil surface, or both.

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.

A topsoil separating and spreading apparatus includes a grate and rotor assembly that can be pivotally mounted on the top of a standard loader bucket for operation. The spreader member includes an arcuate grate formed with slotted openings and a rotor rotatably mounted concentrically with the arcuate grate so that disks mounted on the rotor shaft will move adjacent to the arcuate grate to push topsoil through the grate openings. The spreader member is pivotally movable between opened and closed positions and is powered by the prime mover. The opening of the spreader member allows a supply of topsoil to be loaded into the bucket loader, after which the spreader member can be closed against the bucket to force topsoil to be discharged therefrom through the grate openings. The rotor breaks up clumps within the bucket, while the grate prevents the discharge of non-frangible debris from the supply of topsoil.
