Abstract Trimming apparatus for prunning hedges and the like wherein at least one circular disc having teeth round its periphery is positioned adjacent a plate member and preferably between parallel, spaced apart plate members having first teeth along edge portions thereof. Said second teeth are positioned to at least partially overlap said first teeth as said circular discs are rotated by a drive means. Preferably said first teeth are positioned along opposite, substantially parallel edge portions and said second teeth overlap first teeth along each said parallel edge portion. In addition, a catching means is preferably provided for collecting the trimmings as they are cut and directing them to one side of the apparatus.
