Abstract
A gearbox head is provided for a motor-driven, manually guided implement for driving a cutting tool. The gearbox head includes a housing having a planetary gear arrangement, preferably a bevel gearing. At least one gear of the planetary gear arrangement is fixedly disposed on a shaft that, for venting the housing, is provided with a channel that opens out beyond the housing via an outer opening and opens out into an interior of the housing via at least one inner opening, which is formed by at least one portion of the channel that extends essentially radially relative to the longitudinal axis of the shaft.
