NOVELTY - A machine to turn over rotting material, and especially compost, has a turning drum (10) which swings or can be swung, and can be set at an acute angle to the working line (A) followed by the machine (1). The conveyor for the compost is behind the turning drum (10), and across the working line (A).    USE - The machine is for turning over rotting material, and especially compost.    ADVANTAGE - The turning machine can be used effectively where the compost is laid in restricted spaces.    DETAILED DESCRIPTION - A machine to turn over rotting material, and especially compost, has a turning drum (10) which swings or can be swung, and can be set at an acute angle to the working line (A) followed by the machine (1). The conveyor for the compost is behind the turning drum (10), and across the working line (A). The turning drum (10) is on a shaft within a housing (13) at the machine (1), and the conveyor is parallel to the shaft. The conveyor has a continuous belt, around two deflection rollers. The spreader is parallel to the shaft of the turning drum (10), as a continuous belt around two deflection rollers. The leading end of the conveyor is at the trailing end of the spreader, so that the compost picked up by the turning drum (10) is carried by the conveyor for transfer to the spreader.    The conveyor and the spreader are together in a combined assembly. The spreader is aligned at an upwards and adjustable angle. The turning machine (1) has a mounting block to be attached to a vehicle (F), with a holder connected to the housing (13) of the turning machine (1) to carry it. The holder has at least one cylinder with a sliding piston and closed at one end. The holder is in a swing mounting at the housing (13), projecting from the rear side of the turning machine (1).    A steering mechanism (16), preferably with a swing movement, is at one side surface of the housing (13). At least one further drum can be over the turning drum (10), and especially a turning or dosing drum, rotating against the direction of the turning drum (10) rotation and/or at a variable gap from it and/or with a swing movement in the turning machine (1). The housing (13) has a protective shrouding (17) over the turning drum (10), and a beating plate over the spreader.
