Abstract: 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.

Abstract: A hand-guided power tool has a support arm and a tool member supported on the support arm. A drive motor is provided and a drive belt is rotatably driven by the drive motor and drives in turn the tool member. The support arm has a belt chamber in which the drive belt is arranged. The belt chamber is closed off relative to the environment and sealed off relative to the environment.

Abstract: A two-stroke engine has an intake arrangement including a carburetor. An intake channel divides into a mixture channel and an air channel. An intermediate flange is mounted between the carburetor and the cylinder. This flange has a carburetor connecting surface, which faces toward the carburetor, and a cylinder connecting surface which faces toward the cylinder. Referred to the flow direction in the intake channel, the air channel divides upstream of the cylinder connecting surface into two branches. The first branch has a first longitudinal center axis and the second branch has a second longitudinal center axis. The intersect points of the center axes with the connecting surfaces are mutually connected via an imaginary connecting line in the carburetor connecting surface or the cylinder connecting surface. The two connecting lines conjointly define an angle ? in the carburetor connecting surface with this angle being greater than 0°.

Abstract: A centrifugal clutch, especially in a hand held work apparatus, such as a cut-off machine (1), a brush cutter or the like, having a rotational axis (20), at least one movably mounted centrifugal weight (25) arranged at the drive end and a clutch drum (16) arranged at the output end. The centrifugal clutch (15) includes a brake device (18) which is released by the centrifugal weight (25) when the centrifugal weight (25) moves radially outward in relation to the rotational axis (20).
