Abstract: A towed agricultural implement including a support frame, with one end adapted for connection to a towing vehicle, a drive apparatus carried by the support frame, with one end of the drive adapted for connection to the towing vehicle, support arms carried from the support frame, where each of the support arms are moveable between a working position and a transport position, and each support arm includes at least one rotary rake adapted to be driven about a central rake axis, a drive arrangement connecting the rotary rake to the drive apparatus, and an intermediate drive element connecting the drive apparatus and the drive arrangement moveably supported from the support frame to ensure that a sufficient overall length is available for the displaceable arm drive arrangement in the transport position.

Abstract: A composite material, a composite component made thereof, and a method for producing a metal-ceramic composite material or a composite component are provided. The composite material or the composite component is produced by the method described in the following. In a first step, a porous ceramic preform is produced from a ceramic starting mass, and in a second step the infiltration of the porous ceramic preform with a molten metal takes place, the ceramic starting mass having a ceramic main component and a ceramic minor component that reacts with this main component, and the minor component reacts at least partially with the main component during the first and/or second step.
