A self-propelled work apparatus, especially a lawnmower, includes a chassis, at least one tool and a drive motor for driving the tool. The tool is height-adjustable with respect to the chassis. A setting unit is provided to set the relative position of the tool with respect to the chassis. The setting unit includes an actuating motor and a setting gear. The setting gear rotates by less than one full revolution between a first, lower end position of the tool and a second, upper end position of the tool. A detection device is provided to detect the height position of the tool. The detection device includes encoding elements on the setting gear and at least one detector. The at least one first encoding element for the first end position differs from the at least one second encoding element for the second end position.

A blade for a mowing unit for a lawnmower and/or a motor scythe is substantially parallelogram-shaped. The blade has a slot, wherein the slot is designed to receive a blade-holding element of the mowing unit such that the blade can rotate about the blade-holding element and move in translation relative to the blade-holding element for one cutting position of the blade defined by one end of the slot having one cutting orientation of the blade and another cutting position of the blade defined by another end of the slot having another cutting orientation of the blade. A line segment delimited by the ends of the slot does run non-parallel to sides of the parallelogram, and the parallelogram has an obtuse internal angle.

An autonomous mobile green-area treatment robot has a treatment tool, a protection device, and a height-adjustment device. A tool height of the treatment tool is adjustable. The protection device is configured to protect against access into the treatment tool. A protection height of the protection device is adjustable. The height-adjustment device is configured for the coupled adjustment of the tool height and the protection height together, such that a tool height adjustment value of the adjustment of the tool height and a protection height adjustment value of the adjustment of the protection height are different. A distance between the treatment tool and the protection device is changed.

A garden tool has a controllable travel drive system, wherein the travel drive system is designed to propel the garden tool, and a speed control device, wherein the speed control device has a user-operable operating element and a displacement sensor device. At least one sensor part of the displacement sensor device is supported so as to be movable in translation. The operating element is designed by its operation to displace at least the sensor part in translation. A sensor signal of the displacement sensor device is dependent on a translational position of at least the sensor part. The speed control device is designed for controlling the travel drive system for the variable setting of a travel speed of the garden tool in accordance with the sensor signal.

Garden tool

A cutting mechanism for a lawnmower and/or a motor scythe has at least one tool device, a tool connecting device, and a securing device. The tool device is designed for cutting grass. The tool connecting device is designed for rotation around a cutting mechanism rotation axis of the cutting mechanism. The tool connecting device and the tool device are designed to form a positive connection to one another in order to secure the positively connected tool device against being released from the tool connecting device radially in a radial direction with respect to the cutting mechanism rotation axis. The securing device and the tool connecting device are designed to be at least partially adjustable relative to one another in, or counter to, an at least partial radial direction at least section-by-section between an enable position for enabling production and/or release of the positive connection and a securing position for securing the positive connection against release.
