Provided is a mobile electric work machine that can avoid overload operation of working parts. The mobile electric work machine is an electric lawn mowing work machine (100) that carries out work by working parts (10A, 10B) driven by electric power supplied by blade inverters (14A, 14B) while being run by a running part (20). The blade rotational velocity (Vba) of a blade (11A) or the rotational velocity (Vbb) of a blade (11B) is controlled such that the work load on the working parts (10A, 10B) is constant on the basis of blade inverter current values (Iba, Ibb) from blade inverters (14A, 14B).
