Drawbars are in common use with rail transport; road trailers, both large and small, industrial and recreational; and agricultural equipment.
This was partly made redundant with Ferguson's development of the three-point linkage in his famous TE20.
A wooden drawbar extends from the front of a wagon, cart, chariot or other horse-drawn vehicles to between the horses.
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.
