A machine (100) includes an engine system (190), a walkway (240) for the engine system (190), and a cover assembly (178) to cover the engine system (190) and the walkway (240). The cover assembly (178) includes a hood (220) covering at least a portion of the engine system (190) in the closed position, and defines an underside (228) to face the engine system (190). A handrail (254) is pivotably coupled to the underside (228), and is movable to an extended state and a retracted state. A pin with a shaft and a boss is coupled to the handrail (254). An elongated member (see fig. 6), pivotably coupled to the underside (228), has an end portion bent towards the handrail (254). A slot is structured along a length of the elongated member and extends into the end portion to define a keyhole. Upon a movement of the handrail (254) to the extended state, the boss falls into the keyhole to lock the handrail (254) with the elongated member. The machine may be a construction machine such as a cold planar, rotary mixer, or hydraulic excavator, or a forest, mining, or agricultural machine.
