ABSTRACT:
The present invention relates to a modified extension part (1) and sweeper body (6) for weed mowers, in which the mentioned extension part (1) is constructed as a cylindrical disc provided with through and through recesses (7) and at least two opposite to each other not through and through milled-out recesses (5, 51) to receive in a very inventive way the triangular or polygonal bushes (15) with sweeper body (6) constructed as steel cable (14), and pressed on the end a preferably triangular bush or cover (15), in which locking is done by means of a spring loaded blocking pin (10) and can be pushed in with the thumb and finger to replace the sweeper body for which a recess (16) comes free and the sweeper body can be replaced, through which in a surprising easy way and without the requirements of tools the sweeper body (6) of the extension part (1) can be replaced.
