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.

A system for detecting plugging of ground-engaging tools of agricultural implements includes an aft sensor(s) configured to capture data indicative of a post-worked residue coverage of a portion of a field aft of a ground-engaging tool(s). The system includes a controller configured to monitor the data received from the aft sensor(s) and determine the post-worked residue coverage for the portion of the field. The controller is configured to identify when the ground-engaging tool(s) is experiencing a plugged condition based at least in part on the determined post-worked residue coverage for the field.

An apparatus and system for positioning a trailing wheel behind a row planting unit in a row planting system and for transferring weight between a row closing unit with row closing wheels and a trailing wheel while providing for independent movement of the trailing wheel and row closing wheels is provided. A trailing or firming wheel assembly is positioned behind a row closing unit with a set of row closing wheels. A cam-based depth limiting system provides for a depth stop and depth limiting adjustments while providing for independent movement of the trailing wheel and set of row closing wheels.

Described herein are implements, systems, and methods for applying stress to agricultural plants of agricultural fields. In one embodiment, an agricultural implement comprises a frame transverse to a direction of travel of the agricultural implement and a stress mechanism disposed on the frame in operation such that the stress mechanism applies a force to the row of plants as the agricultural implement moves through the field.

A semi-mounted reversible plow with a headstock for attachment to a tractor, a stabilizer which is connected to the headstock and on which a plow frame carrying two rows of plow bodies is mounted by way of at least a front turning arm in a manner rotatable about a horizontal turning axis, wherein an offset rocker in a rotatable manner to the turning arm and a front furrow rocker connected in an articulated manner to the offset rocker and in a rotatable manner to the plow frame, on the other hand, are arranged between the plow frame and the turning arm, and wherein the rockers can be moved by an adjustment actuator to positions causing different transverse distances between the headstock and in the direction of travel of the foremost plow body, such that the semi-mounted reversible plow is configured to selectively assume a furrow working position and an on-land working position.

A system for detecting the operational status of ground engaging tools for agricultural implements includes an agricultural implement including a frame and a ground engaging tool coupled to the frame. The system further includes one or more sensors supported relative to the frame. The sensor(s) are configured to capture data indicative of a fluid flow past the ground engaging tool as the agricultural implement is moved across the field. The system further includes a controller configured to monitor the data received from the sensor(s) and identify an operational status of the ground engaging tool based at least in part on a comparison between one or more monitored values associated with the fluid flow past the ground engaging tool as the agricultural implement is moved across the field and a predetermined threshold value.
