Abstract: Appliance for scrub clearance, grass cutting or the like, with multiple lines as cutting elements, with a casing in two parts (51, 53) coupled together and containing at least one spool on which said lines are wound, comprising: devices (77A, 77B) for coupling and decoupling of said parts (51, 53); resilient devices (75) designed to maintain said coupling devices in the hold position; and, of one piece with one (53) of the said two parts, devices for effecting connection (80) between said part and said spool (81), whilst the other (51) of the said parts exhibits outlet bushes for the ends of the lines (F); an intermediate bowl-shaped component (99) designed to be coupled to the rotary drive hub (95); and quick-release coupling devices (100,112) for coupling up said intermediate component (99) and the casing (51, 53) of the appliance, to ensure that the appliance is firmly supported by and rotated with the intermediate component (99).

Abstract: A lawn and bush cutting device comprises a housing mounted for rotation about an axis with a drive shaft fixed to the housing and drivable by a motor for rotating the housing. A wire cylinder is coaxially mounted in the housing and can be held fixed with respect to the housing for rotation therewith. A supply of cutting wire is wound on the wire cylinder, or on a reel rotatably fixed to the wire cylinder. A length of the wire extends out of the housing to act as a cutting tool when the housing rotates. A sleeve member is axially movable in the housing and has helical coupling piece which are coupled to helical piece in the cylinder. Axial movement of the sleeve thus causes relative rotation between the wire cylinder and housing, thus paying out additional lengths of wire from the housing. A ring is axially moveable but rotationally fixed to the sleeve and can be moved downwardly by cable operated member.
