# Server device

## Abstract

A server device includes an area setting unit that sets a first area in which a first lawnmower executes first lawn-mowing work in a work area and a second area in which a second lawnmower executes second lawn-mowing work in the work area, a time calculation unit that obtains a first time necessary for the first lawnmower to execute the first lawn-mowing work in the first area and a second time necessary for the second lawnmower to execute the second lawn-mowing work in the second area, a machine number calculation unit that obtains the number of first lawnmowers and the number of second lawnmowers based on the first time and the second time, and a notification unit that notifies the number of first lawnmowers and the number of second lawnmowers to a smartphone. Consequently, a user can check the number of first lawnmowers and the number of second lawnmowers.
