Three-Point Hitch iformation

**Not all three points are created equal**

The three-point hitch is a standardized method of attching implements (equipment) to tractors, first developed by Harry Ferguson in the 1920s. The hitch uses two lower connection points and one upper point which provides a rigid connection. Hydraulic cylinders operate on the lower arms to raise and lower the implement. An additional hydraulic arm may act on the upper arm to control the draft (depth) of tillage equipment. A significant advantage of the three-point hitch is that it converts the drag of the equipment into a downward force on the rear of the tractor. This means that the traction is maximized when the pulling is most difficult.
