Metal bars that are pulled or drawn to operate or control machinery, or the plural of drawbar used in mechanical systems.
From 'draw' (Old English dragan, meaning to pull) + 'bar' (Old English barre). The compound emerged in industrial contexts where bars were physically drawn to engage mechanisms.
Drawbars are essential in locomotives and printing presses—they're literally the hardware that connects the pulling force to the machine. Without these simple bars, trains couldn't couple together and heavy machinery couldn't function.
