An agricultural planting system for controlling the depth of an opener device comprising: an agricultural planter; an opener device mounted on the agricultural planter for engaging the ground of a field; a gauge wheel mounted on the agricultural planter for rotating on the ground of the field; a GPS device coupled to the agricultural planter, the GPS device configured to determine a location of the agricultural planter in the field; and a controller in electrical communication with the agricultural planter and the GPS device, the controller having predetermined settings associated with a map of the field, the controller being configured to select a relative elevation of the opener device and the gauge wheel based at least in part on the location determined by the GPS device, and produce, based on the location, a signal for adjusting the depth of engagement into the ground of the opener device.

An agricultural implement system includes a down force cylinder configured to apply a downward force to a row unit, and a depth control cylinder configured to vary a penetration depth of a ground engaging tool of the row unit. The agricultural implement system also includes a valve assembly in fluid communication with the down force cylinder and the depth control cylinder. The valve assembly is configured to automatically adjust the downward force by varying fluid pressure within the down force cylinder based on fluid pressure within the depth control cylinder.

An agricultural machine includes a main frame, an adjustable frame coupled to the main frame and, a row unit which includes a linking arm coupled to the adjustable frame, and an actuator coupled to the main frame and the adjustable frame. The agricultural machine also includes a controller configured to command the actuator to move to various positions based on signals received from one or more sensors. The one or more sensors are configured to measure one more indicators associated with an actual height of the row unit relative to ground.

An aerator for a turf surface has a traction control, an OPC bail, and an aeration bail capable of single handed operation. A controller automatically lowers a tine head to begin aerating at a start location marked when the aeration bail is closed and lifts the tine head to end aeration at an end location marked when the aeration bail is released. The controller further causes the tines that enter the turf surface at the start location to penetrate to a desired hole depth. The controller also automatically adjusts ground speed to maintain a desired hole spacing during an aeration pass, but permits the operator to speed up during a turnaround between passes with a steerable front wheel freewheeling to mitigate wheel scrubbing. A handle assembly having a spring counterbalance is height adjustable and automatically engages a parking brake when placed in an upright non-operating position.

An agricultural planting implement includes a first wing toolbar configured to support a first set of row units and a second wing toolbar configured to support a second set of row units. The agricultural planting implement also includes a connection assembly having at least one arm pivotally coupling the second wing toolbar to the first wing toolbar. The at least one arm is pivotally coupled to the first wing toolbar and non-pivotally coupled to the second wing toolbar. In addition, the connection assembly includes an actuator configured to drive the second wing toolbar to rotate upwardly relative to the first wing toolbar from a working position to a transport position. The actuator is also configured to urge the second wing toolbar downwardly toward a soil surface while the second wing toolbar is in the working position.

A system for controlling an operative parameter of a harvesting header of an agricultural harvesting machine comprises a first sensing arrangement for sensing a property of a field in front of the header in a contact-less manner, a second sensing arrangement for providing a signal suited to derive a value of an adjustable work parameter of the header, an actuator for adjusting the work parameter, and a control unit for determining a control signal for the actuator based on the signal from the first sensing arrangement and on the signal from the second sensing arrangement. The second sensing arrangement is arranged to detect the position of a reference point, which indicates the work parameter, in a contact-less manner, and that the first sensing arrangement and the second sensing arrangement are relatively fixed.

A disk assembly for agricultural implements comprises a disk hanger including a proximal end and a distal end opposite the proximal end. The disk assembly further includes a hanger spindle supported relative to the distal end of the disk hanger for rotation about a first axis of rotation, and a blade spindle supported relative to the hanger spindle, with the blade spindle being rotatable about a second axis of rotation oriented non-parallel relative to the first axis of rotation. Additionally, the disk assembly includes a blade coupled to the blade spindle for rotation therewith about the second axis of rotation. Moreover, the disk assembly is configured such that rotation of the hanger spindle relative to the disk hanger about the first axis of rotation results in an adjustment of both an angle-of-engagement and a camber angle of the blade.

A system for monitoring the installation status of shank attachment members of an agricultural implement includes a shank assembly having a shank extending between a proximal end and a distal end opposite the distal end, with the proximal end of the shank being configured to be coupled to a portion of the agricultural implement. The shank assembly also includes a shank attachment member configured to be coupled to the distal end of the shank. The system further includes a load sensor provided in operative association with the shank assembly and being configured to generate data indicative of a load transmitted through the shank assembly. In addition, the system includes a computing system communicatively coupled to the load sensor, with the computing system being configured to determine an installation status of the shank attachment member relative to the shank based on the data received from the load sensor.

An agricultural implement includes a transversely extending frame forming a first, a second, and a third frame section. A first actuator is coupled to the first frame section, a second actuator coupled to the second frame section, and a third actuator coupled to the third frame section. Sensors are coupled to each frame section to detect a height of the respective frame section relative to an underlying surface. A control unit is disposed in electrical communication with the sensors and operably controls the actuators to adjust the height of each frame section.
