Abstract

A work machine comprising a work unit that performs work on a travel path, an internal combustion engine configured to generate power for driving the work unit, a traveling unit including a front wheel and a rear wheel, an electric motor configured to generate power for driving a first wheel of the front wheel and the rear wheel, a first clutch for switching between transmission and discontinuation of the power from the internal combustion engine to a second wheel of the front wheel and the rear wheel, and a switching control unit configured to control the first clutch based on a power consumption of the electric motor for switching between the transmission and the discontinuation.

Dependent claims

A work machine, comprising:

a work unit that performs work on a travel path;
an internal combustion engine configured to generate power for driving the work unit;
a traveling unit including a front wheel and a rear wheel;
an electric motor configured to generate power for driving a first wheel which is one of the front wheel and the rear wheel;
a first clutch provided in a power transmission path between the internal combustion engine and a second wheel which is the other of the front wheel and the rear wheel, configured to be switched between a transmission state and a discontinuation state of the power transmission path;
and
