A mower includes a main body having an electric motor configured to drive a mowing member, a pair of front wheels, and a pair of rear wheels. A supporting portion is associated with the main body and a handle is connected to the main body and rotatable between a first position and a second position. The handle comprises an operation assembly operable by a user to control the electric motor. A controller prevents the electric motor from being activated by a user operation of the operation assembly when the mower is in a first state in which the supporting portion and the pair of rear wheels are used to support the main body on a supporting surface with the handle in the first position.

A green area maintenance system includes a motor scythe, a scythe position determining device for determining scythe position coordinates, and a position recording device. The scythe position determining device is attached to the motor scythe. The position recording device is designed for recording a series of scythe position coordinates of a delimiting border while the motor scythe is being guided together with the scythe position determining device along the delimiting border of an area to be maintained.

An electric travelling vehicle including: a motor controller configured to control an electric motor based on displacement of a steering operation part to a forward travel position, a neutral position, and a rearward travel position, a brake controller configured to bring an electromagnetic power-off brake into a released state or a braking state; and a travel state detector configured to detect a travelling state that is accompanied with the released state, a stopped state that is accompanied with the braking state, and a transit stopped state that is accompanied with the braking state.

A hand-held multi-tool device (100) comprising a driving unit (105) and being arranged to carry one of a plurality of replaceable tool heads (150) to be driven by the driving unit (105), the hand-held multi-tool device (100) further comprising a controller (101) configured to: determine a baseline inertial characteristic of the tool head currently being driven by the driving unit; determine an active inertial characteristic of said tool head; and determine a tool type for the tool head (150) based on the active inertial characteristic and the baseline inertial characteristic.

A removably attached operator control unit for controlling operation of an outdoor power equipment machine includes an operator control unit housing, a first joystick and a second joystick extending from an upper housing portion, the first and second joysticks being configured to communicate control actions to a control circuit of the operator control unit, and at least one switch configured to communicate control actions to the control circuit, wherein the control circuit is operable to receive control actions resulting from actuations of the joysticks, and switch and to communicate utilizing an interface arranged between the operator control unit and the outdoor power equipment machine, and when secured to the outdoor power equipment machine, the operator control unit is located at a height that is within about an arm's length or less of an operator standing immediately adjacent to the outdoor power equipment machine.

A self-adjusting mower deck gauge wheel includes a first hydraulic cylinder fluidly connected to a second hydraulic cylinder. A gauge wheel is rotatably mounted on a gauge wheel shaft slideable in the first hydraulic cylinder between a fully extended position and a fully retracted position. In the fully retracted position, the mower deck rests flat on the ground and is not supported by gauge wheels. An orifice between the first and second hydraulic cylinders provides a high damping rate to slow travel of the gauge wheel shaft between the fully extended and fully retracted positions. A coil spring with a low spring rate also may be connected to a piston in the second hydraulic cylinder.

A ground contour sensing system and method for a vehicle with a mowing head. The system includes a sensor system that measures a ground contour in front of the mowing head, and generates contour measurement signals; and a controller that determines whether to move the mowing head based on the contour measurement signals, and generates movement commands for the mowing head when it determines to move the mowing head. The mowing head can include tilt and lift cylinders, and the controller can determine whether to move the mowing head using the tilt or lift cylinders. The sensor system can include a pivot arm that moves in response to changes in the ground contour, and an angle sensor that measures an angle of the pivot arm. There can be one or more sensor systems positioned between the right and left sides of the mowing head.

A work vehicle configured to carry out work travel in a pasture land where harvested pasture grass 1 is present, the work vehicle having a quality determination device 20 configured to determine quality of the pasture grass 1 in the course of the work traveling. The quality determination device 20 includes a cylindrical grass sending tube 21, a grass taking section 22 configured to feed at least a portion of the pasture grass 1 left in the pasture land to an inside of the grass sending tube 21 via a first end of the grass sending tube 21 and a quality determination instrument 9 configured to determine quality of the pasture grass 1 compressed inside the grass sending tube 21.

A mower-conditioner machine which includes a frame, a cutter bar connected to the frame, the cutter bar is configured to cut a crop material from a field, and a crop-engaging member connected to the frame. The crop-engaging member is configured to contact the crop material. The mower-conditioner machine also includes at least one moisture sensor connected to the crop-engaging member. The at least one moisture sensor is configured to sense a moisture content of the crop material.

A lawnmower comprising a housing, one or more cutting blades, and a motor configured to rotate the one or more cutting blades. The lawnmower includes a handle including a switch assembly. The switch assembly includes a contactless switch pivotable about an axis point and a magnet located at the axis point. One or more paddles extend from the handle. The rotation of the one or more paddles causes the contactless switch to pivot about the axis point. The lawnmower includes a sensor configured to sense a variation of a magnetic field of the magnet, and a controller coupled to the motor and the sensor. The controller is configured to receive, from the sensor, a value associated with the variation of the magnetic field of the magnet, and control the motor based on the value of the variation of the magnetic field.
