Provided is a mower that makes it possible to predict a consumption rate of its battery, a change in the remaining capacity of the battery, the workable time from the state in which the battery is fully charged, and the time when to replace the battery. In a mower 10 equipped with a mowing motor 70 and travel drive motors 20A, 20B, a target rotation speed of the mowing motor 70 and power consumption that are set and input by a user are accepted, and while the set target rotation speed of the mowing motor 70 is maintained, an actual power usage value that varies according to variation in load to the mowing motor 70 accompanying an increase or a decrease in the amount of grass is found, using a battery current measured by a current sensor 132, and a new target rotation speed of the travel drive motors 20A, 20B is calculated from a difference between the found actual power usage value and a set value of the power consumption, whereby a travel speed is controlled such that the actual power usage value falls within the range of the set value of the power consumption.
