The invention relates to a drive system for a motor-operated functional device, which can be used as a multi-function or combination device for soil working or turf care such as scarifying, aeration, chopping, grass mowing, rolling, compacting, edging, or cleaning work, such as snow blowing, sweeping, or for emergency service, such as water pumping, power supply, or the like, comprising a primary drive (19, 20), two bearing modules (B, D) arranged on a base frame of the functional device, and a drive shaft (82), which is rotatably supported on the base frame by means of the bearing modules (B, D) and on which the particular working device (90) is arranged in a rotationally fixed manner, wherein the base frame has two mounting or bearing plates laterally spaced apart for accommodating the bearing modules (B, D), which mounting or bearing plates extend perpendicularly to the axis of rotation of the working device (90) that is being used. According to the invention, in order to be able to change the provided working devices as quickly and effectively as possible and in order to adapt the particular required rotational driving speed and direction of rotation in a simple manner, the bearing modules (B, D) are designed as separate assemblies that can be selectively exchanged with each other by means of one of the mounting or bearing plates by using quick closures, and that the rotational speed ranges and directions of rotation required for the particular task, for the particular working devices (90), are achieved by selecting different combinations of bearing modules (B, D) and drive shafts (82), which drive shafts are connected to the particular working device (90) in a rotationally fixed manner.
