Abstract: The disclosure refers to a method for determining and storing surface conditions for a field, comprising: moving an agricultural machine having an earth-working roller system over a field, the earth-working roller system comprising an earth-working roller assembly; detecting sensor signals for an oscillating movement of the earth-working roller assembly; detecting position data for the movement of the earth-working roller system over the field; generating a digital surface map for the field indicative of position-dependent roughness and/or leveling information, the generating comprising assigning the sensor signals to the position data; and storing the digital surface map in a data storage device. Further, a system for determining and storing surface conditions for a field is provided.

Abstract: The present disclosure refers to a method for controlling operation of an agricultural system, comprising a tractor; an implement (100) hitched through a draw bar (10) to the tractor, the implement (100) having working tools (31) configured to engage with a ground and/or an agricultural product in operation while the tractor is drawing the implement (100) over a field; and a control system, comprising a control unit (2) and a sensor arrangement (1) connected to the control unit (2) through a control bus (5), wherein the control unit (2) is configured to determine a draft force applied to the implement (100) through the draw bar from measurement signals detected by the sensor arrangement (1); the method comprising operating the implement in either normal mode or field transport mode of operation based on different draft force thresholds.

Abstract: An agricultural machine is provided, the machine comprising a frame, a control system having a plurality of hydraulic cylinders, and a plurality of functional elements provided on the frame and movable in working positions by the plurality of hydraulic cylinders. The control system comprises a synchronization circuit connecting to each hydraulic cylinder from the plurality of hydraulic cylinders, the synchronization circuit configured to synchronize movement of all of the plurality of hydraulic cylinders. Further, a method for operating an agricultural machine is provided.

Abstract: Various strip tilling systems and methods are disclosed. In some embodiments, the strip tilling system includes: at least one strip tilling unit having a support frame and a tilling member mounted to the support frame; a positioning system; map data relating to a field to be tilled, said map data including data identifying areas of compacted ground in the field; and a control system for adjusting the position of the tilling member with respect to the support frame, wherein said control system is arranged to receive signals from the control system, to access the map data, and to automatically adjust the position of the tilling member with respect to the support frame when the control system determines that the tilling member is located at an area of compacted ground.

Abstract: A cutting unit for a disc harrow and/or a seed coulter. The cutting unit includes a cutting blade rotatably mounted about a rotation axis, and a stripping device for stripping earth accumulated on the cutting blade, wherein the stripping device has at least one stripping arm rotatably mounted about the rotation axis.
