Abstract: A gear arrangement is for a handheld electrical apparatus, in particular a hedge trimmer. The gear arrangement includes a housing having a first housing section, a second housing section, and a re-lubrication opening for introducing lubricant into the housing. A planetary gear, which defines a central axis, is disposed in the first housing section, for reducing the gear ratio of a driving movement provided by a drive motor of the electrical apparatus. An eccentric gear unit is disposed in the second housing section for converting a rotational movement, of which the gear ratio has been reduced by the planetary gear, into an oscillation driving movement. The first housing section is assigned an inflow opening for introducing lubricant into the first housing section, and a drain outlet for discharging lubricant from the first housing section. A handheld electrical apparatus includes a gear arrangement.
