A spacer assembly for restricting actuation of a hydraulic cylinder. The spacer assembly comprises a support bracket configured to be secured to the hydraulic cylinder. The spacer assembly additionally comprises a plurality of shims supported by the support bracket, whereby each of the shims is configured to be shifted between an unengaged position and an engaged position. When the shims are in the engaged position the shims are configured to restrict actuation of the hydraulic cylinder. The spacer assembly further comprises a shifting assembly configured to permit a group of at least two shims to be simultaneously shifted between the unengaged position and the engaged position.

The present invention relates to an agricultural implement comprising a main frame supporting a plurality of ground engaging tools, the main frame being transferable between a first configuration, in which a first plurality of ground engaging tools are in a working position, and a second configuration, in which a second plurality of ground engaging tools are in a working position. A first depth wheel is connected to the main frame and capable of adjusting a working depth of the first plurality of ground engaging tools, when the main frame is in its first configuration. A second depth wheel connected to the main frame and capable of adjusting a working depth of the second plurality of ground engaging tools, when the main frame is in its second configuration. At least the first depth wheel is pivotable in such a way that the first depth wheel moves with respect to the second depth wheel.

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 implement broadly includes a ground-engaging tool, a time-of-flight sensor, and a controller. The time-of-flight sensor is configured to obtain information indicative of seed parameters, furrow parameters, and/or soil condition parameters. The controller is configured to process the information obtained by the time-of-flight sensor to generate the parameters, wherein the controller is further configured to automatically control operation of one or more components of the implement based on the parameters.

In one aspect, the present subject matter is directed to a system for managing material accumulation relative to a ground engaging assembly of an agricultural implement. The system may include one or more ground engaging tools of the ground engaging. assembly, a sensor detecting material accumulation relative to the ground engaging tools, and a controller communicatively coupled to the sensor. The controller may receive an input from the sensor associated with material accumulation relative to the ground engaging tools. The controller may further access data associated with an amount of crop residue present and data associated with a moisture content of soil within the field. Additionally, the controller may determine an accumulation type of the material accumulation based at least in part on the crop residue data and the soil moisture data,

An agricultural machine includes a frame, and a lifting unit configured to vary a height of an operating unit with respect to a supporting surface for the machine. The lifting unit includes hydraulic cylinder with a liner and first and second pistons both slidingly housed inside the liner and arranged in series to define first and second chambers inside the liner, wherein the first and second pistons are controllable independently. The lifting unit includes a pressure stabilizer in fluid connection with the first chamber and that controls a pressure in the first chamber so that the first piston moves therein as a force generated on the first piston varies. A second control element for the second chamber carries out a volumetric control of the second chamber to control a position of the second piston regardless of a pressure inside the second chamber.
