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 vegetation cutter comprises: a frame rod having a longitudinal axis and a front end; a rotary cutter mounted on the front end of the frame rod; a drive motor for driving the rotary cutter; a grip disposed around the frame rod and having an external surface to be held by a user; a power switch trigger arranged on the grip for energizing the drive motor; and a safety lock mechanism for rendering the power switch trigger inoperative when the safety lock mechanism is in a lock position and for rendering the power switch trigger operative when the safety lock mechanism is in a release position. The safety lock mechanism includes a manipulating knob for selectively setting the safety lock mechanism in the lock position and in the release position. The manipulating knob is disposed on the grip at a position circumferentially opposite to the power switch trigger and is turnable around an axis which is parallel to the longitudinal axis of the frame rod to selectively bring the safety lock mechanism to the lock position and the release position.

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.

Abstract: A throttle operating device that adjusts the opening degree of an engine throttle valve is provided. In a throttle operating device according to an aspect of the invention, one end of an inner cable inserted through an outer tube is fixed to a cable fixing part provided in a throttle lever, and the opening degree of the engine throttle valve is adjusted via the inner cable by rotationally operating the throttle lever. The one end of the inner cable is fixed to the cable fixing part with the extending direction of the inner cable changed within the throttle lever. Additionally, a moving mechanism that moves the cable fixing part along a longitudinal direction of the inner cable, is provided in the throttle lever.
