    摘要： To prevent a working machine (1) from moving forward or backward under a state where the accelerator is not being operated.
    The working machine (1) includes a traveling device, a traveling motor (51) to output power to the traveling device, a hydraulic pump (50), including a swashplate, to supply hydraulic fluid to the traveling motor (51), a prime mover to drive the hydraulic pump (50), a first servo-cylinder (61) to set an angle of the swashplate of the hydraulic pump (50), a charge pump (PI) to supply pilot fluid to the first servo-cylinder (61), a switching valve shiftable between a traveling position to supply the pilot fluid from the charge pump (PI) to the first servo-cylinder (61) and a neutral position to stop the pilot fluid supply to the first servo-cylinder (61), a switching operation member operable to select either a traveling mode or a neutral mode, and a controller (90) to shift the switching valve between the traveling position and the neutral position. The controller (90) is configured or programed to hold the switching valve at the neutral position after the switching operation member is operated to select the traveling mode until a rotation speed of the prime mover becomes not less than a first predetermined rotation speed.

    摘要： To improve flexibility of a mounting position of an inching valve (338). A working machine (1) includes a machine body (2), a traveling device (17) travelably supporting the machine body (2), a hydraulic driving device (353) to hydraulically drive the traveling device (17), a floor frame (72) supported on the machine body (2) via a mounting member (303), a pedal (111L, 111R) operable to brake the traveling device (17), the inching valve (338) to change a flow rate of hydraulic fluid supplied to the hydraulic driving device (353) according to operation of the pedal (111L, 111R), and a cable (336) operably connecting the pedal (111L, 111R) to the inching valve (338). The pedal (111L, 111R) and the inching valve (338) are attached to the floor frame (72).
