A system for controlling the depth of at least one closing wheel in an agricultural row unit for planting seeds in a furrow. The row unit includes a firming device that passes the seeds into the soil at the bottom of the furrow, and at least one closing wheel that is pressed into a side of the furrow to close the furrow over the seeds. A control system senses the depth of the closing wheels in the furrow relative to the depth of the firming device, and adjusts the downward pressure on the closing wheel, based on changes in the sensed depth of the closing wheel, to compensate for changes in the hardness of the soil. The up and down movement of the firming device can be adjusted independently of the movement of the closing wheel. The firming device can include multiple holes through which pressurized air is forced to dislodge any dirt or mud that accumulates on the soil-engaging parts of the firming device, and can be made according to an additive manufacturing process that allows narrow channels to be formed internal to the firming device.

A downforce system adjusts the amount of downforce being applied to a row unit of an agricultural implement. The downforce system is controlled to increase or decrease the force on the row unit. A load is sensed at the row unit and compared to either or both of a user defined target and a lower threshold that can be based, at least in part, upon a percentage of a value. When the load is determined to be below the lower threshold, the user defined amount is increased at a rate of change until the load is above the threshold, at which point the increase is stopped, and reduced, if necessary.

An agricultural implement includes at least one row unit having a plurality of support members, each of which is pivotably coupled to an attachment frame or another of the support members to permit vertical pivoting vertical movement of the support members, and a plurality of soil-engaging tools, each of which is coupled to at least one of the support members. A plurality of hydraulic cylinders are coupled to the support members for urging the support members downwardly toward the soil. A plurality of controllable pressure control valves are coupled to the hydraulic cylinders for controlling the pressure of hydraulic fluid supplied to the cylinders. A plurality of sensors produce electrical signals corresponding to predetermined conditions, and a controller is coupled to the sensor and the controllable pressure control valves. The controller receives the electrical signals from the sensors and produces control signals for controlling the pressure control valves.

A bracket for use with an agriculture planter including a trailing arm frame defining a pivot point thereon may include an arm bracket assembly with first and second arms. Each arm may extend from a middle portion of the bracket. First and second implements may be rotatably mounted on mounting ends of two of the arms. The middle portion of the bracket may be pivotally coupled to the trailing arm frame at the pivot point.

A seeding unit comprising: a support; a soil opening member mounted to the support; and a seed delivery outlet, defining an exit aperture for releasing seed; wherein the soil opening member comprises: an upper blade portion operative to form a seed collection slot in the ground; and a lower blade portion laterally offset from the upper blade portion and operative to form a deep rooting slot in the ground that is offset laterally from the seed collection slot.

An agricultural seeding machine includes a trench closer assembly and a sensing device configured to sense an aspect of the soil without contacting the soil and to output a sensed signal corresponding to the aspect of the soil. A processing device processes the sensed signal to generate a processed sensed signal, and compares a characteristic of the processed sensed signal to a stored signal characteristic representative of a soil condition. A trench closure quality metric is determined and provided via a user interface. Additionally, in response to and based upon the comparison, the processing device may automatically adjust the force applied to the soil by the soil contacting member. In this manner, the seeding machine utilizes a feedback signal to determine how well a trench is closed and can adjust the performance of the trench closer assembly in accordance with that feedback.

A row unit downforce system including: a downforce actuator in operational communication with the row unit and constructed and arranged to apply supplemental downforce to the row unit and opening disks; a monitoring system comprising at least one furrow depth sensor constructed and arranged to generate furrow depth values; and a control system module, wherein the control system module is constructed and arranged to generate actuator command signals in response to the furrow depth values.

A trench closing sensor adapted to mount to an agricultural implement to detect whether a seed trench is sufficiently closed with soil to ensure good seed to soil contact. The trench closing sensor may also detect the amount of compaction of the soil over the seed within the seed trench. The trench closing sensor may be in the form of a seed firmer from which a drag wire extends. As the open seed trench and drag wire are covered with soil, instrumentation measures or detects whether the seed trench is being adequately closed with soil by measuring the amount of force required to pull the wire through the soil or by measuring the amount of strain, pulling force or tension in the wire or by measuring the amount of soil pressure acting on the wire. The trench closing sensor may include other sensors for detecting soil characteristics.

Disclosed are a method and/or a system of forming a closing wheel of a planter using a set of interlocking arches to ensure optimum soil-to-seed contact for consistent germination and emergence of a crop. A closing wheel assembly for a planter includes a spiked wheel frame and shoulder frame configured to securely mount onto a closing wheel hub. The spiked wheel frame includes a series of outwardly projected radial teeth configured to penetrate soil to form a seed trench. The spiked wheel frame is formed using a set of arch-shaped interlocking segments having a puzzle element and puzzle slot at its ends. Each puzzle element is configured to fit into the puzzle slot of the adjacent arch-shaped segment to form a circular loop. The shoulder frame evenly closes the seed trench formed by the spiked wheel frame as the closing wheel assembly rotates in the soil optimally covering the seed.

In one aspect, a system for adjusting closing disc penetration depth of a seed-planting implement may include a furrow closing assembly having at least one closing disc configured to penetrate the soil in a manner that closes a furrow formed in the soil by the seed-planting implement. The system may also include an actuator configured to adjust a penetration depth of the at least one closing disc. Furthermore, the system may include a controller configured to receive an input indicative of at least one of an operation of the seed-planting implement or a field condition of a field across which the seed-planting implement is being moved. Additionally, the controller may be further configured to control an operation of the actuator in a manner that adjusts the penetration depth of the at least one closing disc based on the received input.
