A cutting apparatus including a plurality of laser beams for cutting vegetation. The apparatus comprises a housing including side walls being extended generally perpendicular to form a downwardly oriented opening. An electrically powered laser cutting device is positioned centrally within the housing. A transport device is connectable to the housing to provide movement of the housing and laser cutting device along a surface covered by vegetation. The laser cutting device generates at least one laser beam that is directed downward underneath the housing.

A method includes operating an electric implement to move or cut material in an outdoor environment, wherein operating the electric implement creates acoustic sound and managing the acoustic sound by selecting an operating frequency for the electric implement and controlling an electric motor of the electric implement in accordance with the operating frequency.

A work machine includes a control unit that starts cruise control that continues a travel ON mode of the travel unit even if travel levers, functioning as a travel operator, are in a state corresponding to a travel OFF mode. As a result, work is enabled to be performed at constant travel speed with ease.

A harvester including an inlet configured to receive a crop including a stalk, a blade configured to cut the crop into a billet, a sensor configured to detect a three-dimensional appearance of at least a portion of the billet and generate a signal associated with the three-dimensional appearance of the at least a portion of the billet, and a control system having a processor, a memory, and a human-machine interface. The control system is configured to receive the signal from the sensor and programmed to 1) analyze the three-dimensional appearance of the at least a portion of the billet, 2) classify the three-dimensional appearance using an indicator of cut quality and 3) index the indicator of cut quality into the memory.

A control system for an electric, terrain-working vehicle having a left drive wheel powered by a left traction motor, a right drive wheel powered by a right traction motor, at least a first implement powered at least by a first implement motor, and a battery supplying power to the left traction motor, the right traction motor and the first implement motor when certain conditions are met. The control system comprises a first implement controller comprising logic to control the battery-supplied power to the first implement motor; a left traction controller comprising logic to control the battery-supplied power to the left traction motor; and a right traction controller comprising logic to control the battery-supplied power to the right traction motor. The first implement controller, the left traction controller and the right traction controller are independent from one another.

An autonomous lawnmower system includes a lawnmower capable of being operated in a non-autonomous mode and an autonomous mode. A global navigation satellite system (GNSS) is coupled with the lawnmower. A plurality of cameras and a mobile phone dock are coupled with the lawnmower as well. A drive-by-wire traction control system for controlling the lawnmower is provided as well as a navigation module, that is coupled with the lawnmower. Also, a mobile phone is included that controls and monitors the lawnmower when in the autonomous mode.

A system for monitoring a condition of a sickle of a header of an agricultural machine. The system includes a knife guard mounted to the header, a knife section of the sickle that is configured to move either along or with respect to a surface of the knife guard, and a sensor either mounted to the knife guard or another surface of the header for sensing the condition of the knife section.

The mower includes a mower body having a mower blade portion for mowing grass, a first position estimation unit for estimating a self position of the mower main body using a satellite positioning system, a second position estimation unit for estimating a self position of the mower body using a sensor portion provided in the mower body, a detection unit for detecting a portion covered with grass and tree on a preset travel path, and an automatic travel control unit for causing the mower body to travel on the travel path with reference to the self position estimated by the first position estimation unit, and for causing the mower body to travel by switching to refer to the self position estimated by the second position estimation unit at a portion covered with the grass and tree detected by the detection unit.

A walk-behind self-propelled working machine includes a main body, an operation switch, and a handle device. The main body includes a moving assembly and a drive motor. The operation switch is connected to the drive motor. The handle device is connected to the main body and includes an operation member, a connecting rod, and a sensing device. The operation member includes a gripping portion for a user to hold. The connecting rod is connected to the main body. The sensing device is configured to sense a thrust that is applied to the handle device to drive the walk-behind self-propelled working machine and further includes a pressure sensor and a pressing member. When the gripping portion receives the thrust, the pressing member applies a force along a preset straight line to the pressure sensor to drive the pressure sensor to deform.

A battery-operated mower is provided that includes a chassis supporting a first drive wheel and a second drive wheel, a battery pack, a first electric drive wheel motor interconnected to the first drive wheel and second electric drive wheel motor interconnected to the second drive wheel; one or more electric blade motors; an electric cooling fan in fluid communication with at least one of the first electric drive wheel motor and second electric drive wheel motor; one or more controllers for controlling the rotational speed of the first electric drive wheel motor, the second electric drive wheel motor, and the blade motors; and a left control actuator in communication with a first throttle sensor and a right control actuator in communication with a second throttle sensor, wherein the first throttle sensor and second throttle sensor are in communication with the one or more controllers.
