The invention relates to the application of a spinning muck-spreader for the distribution of manure and similar over agricultural areas, comprising a reservoir (2) and at least two rotating, driven, spinning discs (9) arranged beneath the reservoir on which at least two throwing shovels (10, 11), comprising two pieces and of various lengths are arranged. At least the external part (13, 15) of each of the throwing shovels (10, 11) may be adjusted and fixed in various positions to achieve various lengths of the throwing shovels (10, 11) and can be moved in relation to the inner part (12, 14) of each throwing shovel and into various positions for adjustment of several spreading width ranges. Each throwing shovel (10, 11), comprising an internal (12, 14) and an external (13, 15) part, is embodied as a telescopically-extending and -retracting throwing shovel.
