A method for adjusting an orientation angle of an agricultural implement includes arranging a hitch such that an upper link and at least one lower link is articulated to a support structure of the utility vehicle, and adjusting the orientation angle based on a target length of the upper link. The target length of the upper link is determined as a function of the orientation angle and as a function of a lower link angle.

A closing wheel frame assembly comprising a closing wheel frame, a closing wheel assembly, and a lever arm adjustment assembly. A retaining pin secures a lever arm in a desired position to set an angle or orientation of the closing wheel assembly relative to the frame, seed furrow (trench or trough), or soil surface. Operation of the lever arm changes the angle or orientation of the closing wheel assembly relative to the frame, seed furrow (trench or trough), or soil surface.

A system for adjusting the lateral positioning of wheel assemblies of agricultural implements includes a toolbar extending in a lateral direction and having a substantially circular cross-sectional shape. The system also includes a rail coupled to the toolbar and extending in the lateral direction along a length of the toolbar. Additionally, the system includes a wheel assembly configured to be removably coupled to the toolbar such that the rail is positioned between the toolbar and a portion of the wheel assembly. The wheel assembly includes engagement structure configured to engage the rail when the wheel assembly is installed relative to the toolbar, with the engagement between the rail and the engagement structure being configured to prevent rotation of the wheel assembly about the toolbar.

An agricultural row unit for use with a towing frame hitched to a tractor includes an attachment frame adapted to be rigidly connected to the towing frame, a linkage pivotably coupled to the attachment frame, and a row unit frame having a leading end pivotably coupled to the linkage to permit vertical pivoting movement of the row unit frame relative to the attachment frame. A hydraulic cylinder coupled to the attachment frame and the linkage, for urging the row unit frame downwardly toward the soil, includes a movable ram extending into the cylinder, and a hydraulic-fluid cavity within the cylinder for receiving pressurized hydraulic fluid for advancing the ram in a direction that pivots the linkage and the row unit frame downwardly toward the soil. An accumulator positioned adjacent to the hydraulic cylinder has a fluid chamber containing a diaphragm, with the portion of the chamber on one side of the diaphragm being connected to the hydraulic-fluid cavity in the hydraulic cylinder, and the portion of the chamber on the other side of the diaphragm containing a pressurized gas.

A control system for a tillage implement broadly includes front and rear sensors, a leveling assembly, and a controller. The front sensor is positioned on a front of a central section, wherein the front sensor is configured to obtain height information indicative of a height of the front of the central section above a ground. The rear sensor is positioned on a rear of the central section, wherein the rear sensor is configured to obtain height information indicative of a height of the rear of the central section above the ground. The leveling assembly is configured to adjust a front to rear orientation of the central section. The controller is configured to receive the height information from the front sensor and the height information from the rear sensor, and to provide instructions to the leveling assembly to adjust the front to rear orientation of the central section based on the received height information.

An agricultural machine (10) or, particularly, a mower for an agricultural machine includes a primary frame (13), a mowing unit (14) mounting a cutterbar therein, an adjustable element (17) and a tilt sensor (19). The adjustable element is adjustable in response to a signal from the sensor to re-configure a mowing angle between the cutterbar and/or mowing unit and a ground surface. Such reconfiguration results in adjusting an effective stubble height of the mower. The adjustable element may be positioned between the primary frame (13) and the agricultural machine (10) or between the primary frame (13) and the mowing unit (14). In the latter case the adjustable element (17) provides independent adjustment of a tilt angle of the mowing unit to a primary actuator (A).

An agricultural machine includes a controller disposed in communication with a implement linkage system, an output, and an input. The controller is operable to identify a selected work implement from a plurality of different work implements. A desired operating condition is then solicited from an operator via the output. A selection command is received from the operator via the input indicating which of a float operating condition and a fixed height operating condition is the desired operating condition. The controller may then automatically determine a recommended operating setting for the implement linkage system for the selected work implement and the desired operating condition and notify the operator of the recommended operating setting for the implement linkage system for the selected work implement and the desired operating condition via the output.

A diverter system for a closing assembly includes a diverter configured to couple to an arm of the closing assembly. The diverter has an engagement surface configured to engage an obstacle within a field, and the diverter is configured to drive the arm upwardly in response to contact between the engagement surface and the obstacle to direct a closing disc of the closing assembly over the obstacle.

A method for weeding between rows of crops and between individual plants in each row whereby a weeding rod is suspended at a proximal portion thereof and left un-suspended at a distal portion thereof whereby the suspension keeps the distal portion and proximal portion in the same horizontal plane. The method further comprises the step of ensuring that the weeding rod has a rounded cross section in a transverse plane with respect to a length axis thereof between the proximal portion and the distal portion and the further step of advancing the weeding rod below ground level in a direction along a ground plane.

An apparatus and method are provided for removably mounting an agricultural product sprayer, having at least one foldable boom, on an agricultural product applicator having a chassis adapted for removably receiving the agricultural product sprayer, by attaching the foldable boom to a skid adapted for operative, removable mounting on the applicator chassis. The skid further has a boom cradle adapted for supporting the foldable boom in a folded position when the skid is mounted on the chassis, and when the skid is separated from the chassis of the agricultural applicator. The boom cradle is selectively movable between an inboard and an outboard position of the cradle to facilitate operation of the product applicator, and also to facilitate mounting the sprayer on, and removing the sprayer from the chassis of the applicator.
