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 outdoor treatment system has an autonomous mobile outdoor treatment robot and a sensor and control device. The robot has a chassis and a contact element. The chassis executes a travelling movement in a direction of travel. The contact element executes an avoiding movement in an avoiding direction as a result of the travelling movement and contact between an obstacle and a lower contact point below a height limit, and executes a detection movement in a detection direction as a result of the travelling movement and contact between an obstacle and an upper contact point at or above the height limit. The contact element is mounted to move with respect to the chassis. The avoiding direction and the detection direction are different. The sensor and control device detects the detection movement and controls a robot protective function, and does not detect or evaluate the avoiding movement.

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.
