Assembly for a mobile garden surface-processing device comprises a drive module with an interface having a coupling element, a processing tool module with a coupling element, and an extension module with a drive shaft and a coupling element
Assembly for a mobile garden surface-processing device comprises at least one drive module (12) with a motor drive and an interface (16) having at least one coupling element, at least one tool module (14) with a processing tool having at least one coupling element at an interface, and at least one extension module (13) with a drive shaft (23) and at least one coupling element at an interface. The coupling elements of the modules are joined together to transfer the drive force. Preferred Features: At least one coupling element is a clamping, socket or catch coupling, a tongue and groove connection, or a similar connection. The processing tool is a rotary hoe, a rake, hedge shears, a cutting tool, a grass trimmer, a brush, a lancing tool, or a ground borer.
