Abstract: A shaft system for a portable, manually-guided implement, including an upper connector and a lower connector for connection to adjoining components. The shaft system has a guide tube portion and a drive shaft portion supported in the guide tube portion by at least one support bushing. The guide tube portion is made of carbon fiber reinforced polymeric material. In at least one region of the periphery of the support bushing a first spacing is formed between the support bushing and the guide tube portion, wherein the first spacing is up to approximately 15% of the inner diameter of the guide tube portion. The shaft system can be utilized with a portable, manually-guided implement.
