A work machine includes a machine body, a travel device, a hydraulic drive, a pedal for performing a braking operation, an inching valve that changes a flow rate of a hydraulic fluid, and an adjuster that adjusts a stroke of an operation of the pedal. The adjuster includes a swing member that swings in coordination with an operation of the pedal and that is at a first position when the pedal is at an initial position of the stroke, a movement member that is capable of performing movement in contact with the swing member and that changes the first position by performing the movement in contact with the swing member, and a switching mechanism that is switchable between a first state in which the switching mechanism allows the movement of the movement member and a second state in which the switching mechanism prohibits the movement of the movement member.
