Top five significant developments in ag machinery.

Irishman Harry Ferguson can claim credit for the first hydraulic lift with automatic draft control. By 1933, he had perfected a way of attaching an implement to a tractor by three arms. The tension load on the lower arms and the compression load on the upper arm caused the virtual hitch point to be near the tractor's front axle, thus keeping the front end of the tractor on the ground.
Ferguson's three-point hitch was probably the most revolutionary improvement in tractor and implement technology during the first half of the 20th century. Today, virtually every tractor sold anywhere in the world features a three-point hitch based on Ferguson's original system.

In addition, the top link compression load operated a hydraulic valve that caused the implement depth to be automatically regulated according to the draft needed to pull it.
