A trench closing assembly (250) for a row unit (200) of an agricultural planter, comprising a main frame (251) and a frame member (1520) pivotally supported from the main frame, a pair of closing wheels (254) each rotatably supported by the frame member, a mounting arm (1570) pivotally mounted to said frame member and supporting a press wheel (255) rearward of said closing wheels, including a scraper (3600, 4600) adjacent to an inner side of said press wheel.

A fluid system includes a fluid control assembly in fluid communication with a fluid source in fluid communication with a fluid supply port and the fluid control assembly is in fluid communication with an actuator via an outlet port. A controller controls at least one supply valve and at least one exhaust valve. The at least one supply valve and exhaust valve are in a normally closed position until being actuated by the controller to an open position. The fluid control assembly includes a pressure sensor in communication with the outlet port. Whereby when pressure in the outlet port is less than a predetermined pressure, a controller opens the supply valve to communicate fluid to the actuator via the actuator line and when the pressure in the outlet port is greater than a predetermined pressure the controller opens the exhaust valve to vent the is outside a predetermined range.

A system for planting cover crop seeds in fields with standing row crops, including a high-clearance agricultural vehicle with a high-clearance toolbar, soil sealers, and a seeder with a reciprocator above the soil sealers to deliver various types of seeds onto the disrupted soil after which the soil sealers cover the seeds with soil.

A hydraulic control system for controlling the down force on an agricultural implement comprises a hydraulic cylinder containing a movable ram, a source of pressurized fluid coupled to the hydraulic cylinder on a first side of the ram by a first controllable valve, a fluid sump coupled to the hydraulic cylinder on the first side of the ram by a second controllable valve, and an electrical controller coupled to the valves for opening and closing the valves. The valves may be self-latching valves that remain in an open or closed position until moved to the other position in response to a signal from the controller.

An opener attachment for an agricultural row unit including a frame, an arm pivotally coupled to the frame, an opener disc coupled to the arm and configured to excavate a trench into soil, and a gauge wheel coupled to the arm and configured to block movement of the opener disc into the soil to control a depth of the trench. The opener attachment also includes a mechanical stop coupled to the frame and configured to block the gauge wheel and the opener disc moving toward the soil. In addition, the opener attachment includes an air bag configured to urge the gauge wheel and the opener disc toward the soil.

A seed placement device connected to a machine to transfer seed to a furrow includes a housing having a first opening through which seed is received and a second opening through which seed is discharged. An endless member positioned within the housing, and a drive member that controls movement of the endless member in cooperation with movement of the machine. The machine operates in a seeding direction at a travel speed, and the endless member discharges seed at a discharge speed and in a discharge direction. The discharge direction is approximately opposite to the seeding direction, and the discharge speed of the seed is at least 1.2 times the travel speed of the machine.

A seed planter comprises a frame including a main frame section and a furrowing disk frame section. A plurality of planter assemblies may be connected to the main frame section, and a plurality of furrowing disks may be connected to the furrowing disk frame section. At least one linkage may connect the main frame section and the furrowing disk frame section, and at least one motor may be configured to move the furrowing disk frame section with respect to the main frame section, wherein the at least one linkage permits the furrowing disk frame section to move to a low position for no-till planting and move to a high position for prepared seed beds or conventional planting.

A trough is cut in the ground surface by a rotating member. The rotating member displaces soil upward with respect to the ground surface and rearwardly with respect to a direction of travel of the rotating member. While the soil is in the air, slurry is deposited into the trough. The soil is then redirected downward to the trough to cover the slurry with the soil.
