Walk-behind power equipment includes: a main body provided with at least one front wheel and left and right rear wheels and a work unit; travel motors provided for the respective rear wheels; a handle extending from the main body rearward and upward; at least one of a tilt angle detector that detects a tilt angle of the main body and a load detector that detects a downward load applied to the handle; a yaw rate detector that detects a yaw rate; and a control unit that drive-controls the travel motors. The control unit determines whether the main body is in a rearward tilted state based on the tilt angle or the downward load, and if it is determined that the main body is not in the rearward tilted state, performs straight-line travel control to set a rotational speed difference between the travel motors to reduce the yaw rate.
