Drawbars are in common use with rail transport; road trailers, both large and small, industrial and recreational; and agricultural equipment.
A wooden drawbar extends from the front of a wagon, cart, chariot or other horse-drawn vehicles to between the horses.
A steel drawbar attaches a three-point hitch or other farm implement to a tractor.
By contrast, the fifth wheel is designed to transmit a proportion of the load's weight to the hauling vehicle.
They are made from from high tension material to bear heavy loads while being pulled by the tractor.
