A method for operating an autonomous mobile green space processing robot, wherein the green space processing robot includes a drive system for propulsion of the green space processing robot. The method includes: a) monitoring whether a sticking presumption criterion is met, wherein the sticking presumption criterion is characteristic of suspected sticking of the green space processing robot; b) if the sticking presumption criterion is met, operating the drive system for a movement change of the green space processing robot and monitoring whether a sticking confirmation criterion is met, wherein the sticking confirmation criterion is that the movement change does not occur; and c) if the sticking confirmation criterion is met, initiating a sticking countermeasure of the green space processing robot.

A header for a combine harvester has a primary implement and a secondary implement with a roller unit. The roller unit has a frame element, an outer roller set with a rotatably supported roller and a central roller set with a rotatably supported roller. The central roller set is guided on the frame element to be lowerable relatively to the external roller set.

An agricultural work machine configured to avoid anomalies is disclosed. Agricultural work machines may encounter anomalies, such as obstacles (e.g., tires) or irregularities in the crop (e.g., weeds), which can reduce the quality of the harvested crop. Manually steering the agricultural work machine requires the constant attention of the vehicle operator. Thus, the agricultural work machine is configured to include sensors to generate one or more images (such as images of various regions of the agricultural work machine), an image processing system to process the images and a control unit to avoid the anomalies (e.g., avoid the identified anomalies, to drive in tracks, and/or to stop the agricultural work machine).

A robotic work tool system (200) comprising a robotic work tool (100) and a beacon marker (280), said robotic work tool (100) comprising a beacon sensor (175) configured to sense a signal being transmitted by the beacon marker (280), said beacon marker (280) marking an area (270) around an obstacle (260) in a work area (205) in which said robotic work tool (100) is arranged to operate, wherein said robotic work tool is configured to determine a proximity to a beacon marker (280) and to adapt its operation accordingly.

A cutter guard assembly for a knife drive of an agricultural farm implement is provided. The cutter guard assembly includes a cutter bar assembly, a window frame, and a floor sheet. The cutter bar assembly has a cutter bar and a reciprocating knife assembly operatively connected to a knife drive. The window frame is rigidly attached to the cutter bar. The window frame includes an opening through which a knife arm of the reciprocating knife assembly extends through. The floor sheet extends rearwardly from the cutter bar and pivots relative to the window frame.

An attachment for a commercial grade frontal mower/slasher comprises a forwardly extending member which can be raised and lowered and which extends in front of the mowing direction when in the lowered position. The forwardly extending member contains a plurality of transversely spaced steel fms which have a particular shape such that if the fms strike an obstacle such as a hidden rock in long grass, the fms will cause the forwardly extending member to be lifted which will alert the driver of the obstacle. The forwardly extending member can also be manipulated to allow the obstacle to be dragged away. The fms in the forwardly extending member can also be pushed into clumpy material such as lantana or blackberry and the mower reversed to allow the material to be mowed.

A lawn mower comprising a frame supported on rotatable wheels for movement over a ground surface; an operator support coupled to the frame and configured to support the entire weight of an operator of the lawn mower during use thereof; a blade assembly comprising one or more blades that are configured to cut grass on the ground surface; a steering system configured to manipulate the steering direction of the wheels; a motor assembly configured to: drive the wheels so as to move the frame along the ground surface; and a first rechargeable battery module removably coupled to the frame and configured to power the motor assembly.

A robotic work tool system (200) comprising a robotic work tool (100) and a beacon marker (280), said robotic work tool (100) comprising a beacon sensor (175) configured to sense a signal being transmitted by the beacon marker (280), said beacon marker (280) marking an area (270) around an obstacle (260) in a work area (205) in which said robotic work tool (100) is arranged to operate, wherein said robotic work tool is configured to determine a proximity to a beacon marker (280) and to adapt its operation accordingly.

A method for avoiding collisions when actuating wing assemblies of an agricultural implement may include accessing vision-related data associated with an obstacle collision zone for the agricultural implement and determining whether a wing movement operation can be executed without collision between the agricultural implement and an obstacle based at least in part on the vision-related data. The wing movement operation is associated with moving a wing assembly of the agricultural implement across at least a portion of the obstacle collision zone between a work position of the wing assembly and a transport position of the wing assembly. Additionally, when it is determined that the wing movement operation can be executed without collision, the method may include actively controlling an operation of at least one component configured to facilitate initiation of the wing movement operation.
