A hydraulic height control system controls all raising, lowering and folding movement of agricultural tillage equipment. The system includes a single hydraulic circuit utilizing non-rephase cylinders which allows for independent raising and lowering of the equipment frame sections and tool gangs. The hydraulic circuit also controls the folding of the frame wings between field and transport positions. Sensors monitor component positions. The hydraulic circuit also uses a common rail for providing fluid to the cylinders. The system achieves precise depth control in the high speed tilling agricultural environment by keeping the tilling components at the appropriate depth or operating position

An agricultural vehicle-trailer combination includes a traction module including a drive element for engaging in a ground, a working appliance coupled to the traction module by a coupling apparatus, and a folding axle supporting the working appliance relative to the ground at least during a transport mode. A slewing mechanism of the coupling apparatus provides a degree of freedom of rotation between the traction module and the working appliance along a longitudinal axis of the working appliance. A pivot joint provides a degree of freedom of pivoting between the traction module and the working appliance along a vertical axis of the traction module. The pivot joint is adjustable relative to its pivot angle by a steering actuator for influencing the direction of travel of the vehicle-trailer combination.

An orientation control system for an agricultural implement includes a first sensor configured to be positioned at a left end portion of a frame. The first sensor is configured to emit a first output signal toward a soil surface and to receive a first return signal indicative of a first height of the left end portion. The orientation control system also includes a second sensor configured to be positioned at a right end portion of the frame. The second sensor is configured to emit a second output signal toward the soil surface and to receive a second return signal indicative of a second height of the right end portion. In addition, the orientation control system includes a controller configured to control first, second, and third actuators such that a difference between the first height and the second height is less than a threshold value.

A system for identifying plugging within an agricultural implement is provided. The system includes a ground engaging tool configured to be supported by the agricultural implement. A weight sensor is operable to measure a weight of one or both of the ground engaging tool and the agricultural implement. A controller is communicatively coupled to the weight sensor. The controller is configured to receive, from the weight sensor, a signal that corresponds to the weight of one or both of the ground engaging tool and the agricultural implement. The controller is further configured to determine when the ground engaging tool is plugged based at least in part on the signal from the weight sensor.

An agricultural device for soil processing with two sets of working rollers comprises a supporting frame, which comprises a central part, a left wing and a right wing. The left and right wings are rotatably attached to the central part. At least two rows of working units are attached to the supporting frame. The working units are arranged in regular distances in every row. A left set of rollers is attached to the left wing and a right set of rollers is attached to the right wing. The sets of rollers are divided into front rollers and rear rollers and provided with attachments and discs. The discs on the sets are located between these attachments. The number of discs of rear rollers differs exactly by one disc from the number of discs of front rollers. The distances between individual discs are the same along the whole width of the agricultural device. The discs of front rollers are located in the same plane as the working units.

A tangible non-transitory computer readable medium includes instructions that, when executed by a processor, are configured to cause the processor to detect a movement state of an agricultural implement and automatically retract a stabilizer of a stabilization system from an extended position to a retracted position in response to detecting the movement state of the agricultural implement. The stabilizer is connected to a rear portion of a frame of the agricultural implement, and the stabilizer is configured to support a weight of the rear portion while in the extended position.

A closing wheel assembly is provided for a row unit agricultural planter. The planter is configured to open a trench in the soil and the closing wheel assembly is configured to close the trench. A resilient flap is provided for firming and leveling the soil returned to the trench by the closing wheel assembly. Pivotally mounted offset closing wheels are also provided.

The invention relates to an agricultural implement having an auxiliary chassis, which implement is supported by the three-point hydraulics of a towing vehicle and has an additional support wheel, on which a spring force acts, to improve the steerability of the vehicle. A dead center mechanism resiliently lifts the support wheel when the implement is in the working position.

A system for monitoring the wear rates of agricultural implements may include an agricultural implement having ground-engaging tools configured to work a field area, at least one wear sensor configured to generate data indicative of wear of one or more of the ground-engaging tools, and a computing system communicatively coupled to the at least one wear sensor. The computing system may determine a first wear rate of the one or more of the ground-engaging tools based at least in part on the data indicative of the wear of the one or more of the ground-engaging tools and to compare the first wear rate to a threshold wear rate. Additionally, the computing system may perform a control action when a differential between the first wear rate and the threshold wear rate exceeds a wear rate differential threshold.

A tillage implement has a gang of rotary spider tines, each spider tine having a center portion and a plurality of teeth forming a peripheral edge of the spider tine. Each tooth is rearwardly curving from the intended direction of rotation and has a curved leading edge and a curved trailing edge that taper to a rounded outward tip. A distal end of each tooth is angled relative to a tooth base to form a flared paddle such that the flared paddle is angled with respect to the tooth base and center portion of the spider tine. A first set of teeth have flared paddles angled in a first direction and a second set have flared paddles angled in a direction opposite said first direction, with the first set being alternately positioned with the second set in a circumferential pattern around the peripheral edge of the spider tine.
