Abstract: A riding-type electric work machine including a vehicle body frame, an electrically driven operating unit, a swing arm swingably supported by the vehicle body frame, a traction motor held by the swing arm, a battery and a suspension coupled to the swing arm. The swing arm includes a housing base enclosing the traction motor and an arm connecting the housing base to the swing shaft.

Abstract: A riveted joint is described herein. The riveted joint includes a first component and a second component. The first component includes a first opening, and a plurality of first tabs and a plurality of first notches defined along a periphery of the first opening. The second component includes a second opening aligned with the first opening. The second component further includes a plurality of second tabs defined along a periphery of the second opening, wherein at least one second tab is aligned with at least one first notch to define an interlock zone when the first and second components are in a predetermined orientation relative to each other. The joint also includes a rivet extending through the first and second openings. The rivet is configured to secure the at least one second tab within the at least one first notch such that the first and second components are rotationally interlocked.

Abstract: A knob for mounting on a control lever includes a knob body and a cavity formed in the knob body extending from a lower end of the knob body having a lower opening. The knob also includes a cantilever arm within the cavity connected to an interior connection portion of the knob body remote from the lower opening and extending substantial parallel to an interior of the knob body to the lower opening. The cantilever arm includes a projection formed on a side of the cantilever arm to engage a connecting portion of the control lever.

Abstract: Systems and methods for mounting a timing belt pulley to a crankshaft can include a crankshaft rotatable about a center longitudinal axis, the crankshaft including a pin assembly configured for connection to a reciprocating piston. A timing belt pulley can be positioned against the pin assembly and configured for engaging the pin assembly such that the timing belt pulley is coupled to the crankshaft for rotation about the center longitudinal axis. For example, the pin assembly can include a slot formed on an exterior surface thereof, and the timing belt pulley can include a key extending towards the pin assembly and configured for engaging the slot.
