Abstract: A handcart may include a frame; a drive wheel rotatably supported by the frame about a rotation axis extending in a right-left direction; a prime mover configured to rotate the drive wheel; a bracket pivotably supported by the frame about a pivot axis extending in an up-down direction; and a non-drive wheel supported by the bracket about a rotation axis extending in a direction perpendicular to the up-down direction. The non-drive wheel may include a first non-drive wheel and a second non-drive wheel, and the first non-drive wheel and the second non-drive wheel may be configured to be rotatable independent of each other.

Abstract: A handcart may include a chassis unit and a container unit configured to be detachably attached to the chassis unit. The chassis unit may include a front wheel unit rotatably supporting a front wheel; a rear wheel unit rotatably supporting a rear wheel; a chassis frame extending in a front-rear direction and supporting the front and rear wheel units; and a prime mover configured to rotate at least one of the front wheel and the rear wheel as a drive wheel. The container unit may be selected from a group including at least a first container unit and a second container unit. The first container unit may include a first container and a first container frame extending in the front-rear direction and supporting the first container. The second container unit may include a second container and a second container frame extending in the front-rear direction and supporting the second container.

Abstract: A handcart may include: a support frame; a container; a lock member configured to move between a locking position at which the lock member restricts rotation of the container relative to the support frame and an unlocked position at which the lock member allows the rotation of the container relative to the support frame; and a retainer member configured to move between a retaining position at which the retainer member restricts a movement of the lock member from the unlocked position to the locking position and a non-retaining position at which the retainer member allows the movement of the lock member from the unlocked position to the locking position. The lock member may be configured to move from the locking position to the unlocked position and be maintained in the unlocked position by a movement of the retainer member from the non-retaining position to the retaining position.

Abstract: A working machine may include a first ground-contact part, a driving part configured to drive the first ground-contact part, a clutch mechanism configured to be switched between a transmission state and a non-transmission state, a clutch operation part configured to switch a state of the clutch mechanism, a braking mechanism configured to be switched between a braking state and a non-braking state, and a braking operation part configured to switch a state of the braking mechanism. In a case where the state of the braking mechanism is the braking state, the clutch mechanism may be switched from the transmission state to the non-transmission state by operating the clutch operation part, and in a case where the state of the braking mechanism is the non-braking state, the clutch mechanism may not be switched from the transmission state to the non-transmission state even by operating the clutch operation part.
