A method of defining an end travel limit of an electric actuator includes sensing an electric current of the electric actuator while moving the electric actuator from a first position to a second position. A maximum travel current of the electric current sensed during movement of the electric actuator between the first position to the second position is increased by a factor to define a maximum calibration current. The electric current is then sensed while moving from the second position toward an end travel position of the electric actuator. Movement of the electric actuator is stopped at a fault position when the electric current equals the maximum calibration current. The end travel limit of the electric actuator is then defined as a function of the fault position.

A lift detection arrangement in a robotic lawnmower for detecting a lift of a body of the robotic lawnmower relative to a chassis of the robotic lawnmower. The lift detection arrangement includes a collision absorber; and a sensor arrangement including a spring, a movable part, a metal plate and a sensor. The collision absorber is screwed to two plastic parts and arranged to allow a displacement of the body relative to the chassis in a collision plane during a collision between an obstacle and the robotic lawnmower, but not in a vertical direction. The moveable part is arranged to provide a displacement of the body relative to the chassis in a lift direction during a lift of the body. The sensor is configured to sense the distance to the metal plate that is fixed to the moveable part and to trigger a cut off of power to a cutting blade of the robotic lawnmower if the distance becomes greater than a predetermined distance.

An agricultural implement system includes an agricultural implement and a controller. The agricultural implement includes: a chassis; a pickup carried by the chassis and configured to rotate and convey crop material; a movable windguard carried by the chassis; and a windguard displacement sensor associated with the windguard and configured to output windguard displacement signals corresponding to a displacement of the windguard relative to a zero position. The controller is configured to: determine a plug condition exists when the displacement of the windguard exceeds a defined displacement; and output at least one plug condition mitigation signal to adjust at least one parameter of the agricultural implement system and mitigate the plug condition responsively to determining the plug condition exists.

A method for sharpening cutting knives carried by a cutter drum in a housing of an agricultural vehicle includes: rotating the cutter drum while keeping a sharpening door closed so an overpressure is created inside the housing, the sharpening door shielding a sharpening stone from the cutting knives while creating the overpressure; opening a transition door of the housing below the cutter drum to eject crop material through the open transition door; opening the sharpening door to expose the cutting knives to the sharpening stone and closing the transition door; grinding one or more of the cutting knives with the exposed sharpening stone; and closing the sharpening door to shield the sharpening stone from the cutting knives after grinding.

Systems for improving fire safety in agricultural machinery are configured for detecting, at least partially controlling, and/or suppressing adverse fire-related conditions. The adverse fire-related conditions can include sparks, embers, and/or flames in the agricultural machinery.

An agricultural system includes a header and a controller. The controller is configured to receive an indication to operate the agricultural system in a non-harvesting mode, output a first signal to set the header in a set profile upon initialization of the non-harvesting mode, receive sensor feedback indicative of an obstacle position of an obstacle relative to the header while the agricultural system operates in the non-harvesting mode, and output a second signal to adjust the header to deviate from the set profile based on the sensor feedback while the agricultural system operates in the non-harvesting mode.
