A drawbar is a coupling or hitching device consisting of a strong metal bar bearing a hook used for attaching, hauling, or pulling a load behind a powered vehicle. For example, drawbar pull refers to the pulling force or ability of a vehicle to pull a load.
Drawbars are used to couple everything from railcars, to road or transportation trailers, to recreational, industrial, and agricultural equipment. A drawbar for example may be mounted to the rear of a tractor to pull a plow. A drawbar may also be attached to a tow tractor to taxi airplanes out of an airport. Drawbars should be distinguished from fifth wheel coupling. Fifth wheel coupling is designed to transmit most of a load’s weight over to the prime mover or hauling vehicle, whereas a drawbar requires either a trailer to lightly load the drawbar, or where the total weight of the load is equal to the coupling mechanism.
