An agricultural implement system having: a row unit coupled to a tool bar of an agricultural implement; an opener system coupled to the row unit and configured to engage soil to form a trench; a soil condition sensor; a closing system, configured to close the trench created by the opener system, the closing system comprises: a first disk configured to engage the soil and close the trench; a second disk configured to engage the soil and close the trench; and a controller configured to couple to the soil condition sensor and control a position or orientation of the first disk or the second disk in response to feedback from the soil condition sensor.

A seed trench depth sensor is adapted to mount to an agricultural implement. The trench depth sensor determining the difference between a distance measured to a bottom of the seed trench by a first sensor and a distance measured to a surface of the soil by a second sensor disposed rearward of the first sensor.

An agricultural implement system having: a row unit coupled to a tool bar of an agricultural implement; an opener system coupled to a chassis of the row unit and configured to engage soil to form a trench; a downforce system configured to apply a downforce to the row unit to adjust a contact force between the row unit and the soil; a soil condition sensor configured to detect a condition of the soil and/or an operational sensor configured to detect operation of the agricultural implement system; a closing system, configured to close the trench created by the opener system; and a controller coupled to the soil condition sensor and/or the operational sensor, wherein the controller is configured to control the downforce system and the closing system in response to feedback from the soil condition sensor and/or the operational sensor.

A planting system having a plurality of row units, each row unit having: (a) at least one opening disc configured to open a seed trench; (b) a soil engaging member configured to engage a sidewall of the trench during planting; and (c) at least one strain gauge in operative communication with the soil engaging member, wherein the at least one strain gauge measures force on the soil engaging member during planting operations.

A row planting unit closing system including a first stage closing unit adapted to be attached to a row planting unit and including: a first stage frame; and a set of at least one row closing wheel having a closing angle orientation non-perpendicular relative to the ground; and wherein the first stage frame is attached at a first end to the row planting unit, the first stage frame comprising a linkage mechanism for setting a toe in angle orientation of the set of at least one row closing wheel relative to the first stage frame.

A precision pneumatic seed drill. The seed drill comprises at least one sowing element having a seed selector device housing a perforated selector disc which selects seed and has opposing faces subject to a pressure differential. A sowing duct is associated with the selector device. A system measures the speed of forward movement of the seed drill with reference to the ground being sown in order to vary the rotational speed of the selector disc according to the speed of forward movement measured by the measuring system. A pressurization device associated with the selector disc applies the pressure differential to the faces. An ejector along the sowing duct is fed by a compressed air dispenser for pneumatically accelerating the seeds singled out by the selector device. A device for varying the pressure of compressed air fed to the ejector is calibrated according to the typology of the seed to be sown.

A sectional control device controls the flow of particulate material from a meter assembly to a primary manifold of an air seeding system. The sectional control device includes a plate assembly having particulate openings extending between the meter assembly and the primary manifold and a shut-off mechanism configured to control the flow of the particulate material through the particulate openings. The shut-off mechanism includes a gate configured to slide between an open position, where particulate material can flow through the particulate opening, and a closed position, where particulate material is prevented from flowing through the particulate opening. The shut-off mechanism also includes an actuator configured to drive the gate between the open position and the closed position.

A meter roller for an agricultural metering system includes a flute and a recess positioned adjacent to one another along a circumferential axis of the meter roller. The flute and the recess are configured to meter flowable particulate material from a storage tank to a material distribution system via rotation of the meter roller. In addition, a first circumferential extent of the flute is at least 1.5 times greater than a second circumferential extent of the recess along an entire longitudinal extent of the flute and the recess, and the entire longitudinal extent of the flute and the recess is greater than the first circumferential extent of the flute and the second circumferential extent of the recess.

A vacuum system that includes a planter frame. A row unit bracket couples to the planter frame. A fan couples to the planter frame and draws air through a row unit. An exhaust duct extends through the row unit bracket. The exhaust duct couples to the fan and discharges airflow from the fan towards the ground. A diffuser reduces a speed of and/or redirects the airflow as the airflow exits the exhaust duct.
