Techniques

=Introduction= The three-point hitch is a widely used type of hitch for attaching ploughs and other implements to an agricultural or industrial tractor. The three points resemble either a triangle, or the letter A. Three-point attachment is the simplest and the only statically determinate way of joining two bodies in engineering.

Size categories

There are five different hitch sizes, called categories. The higher category hitches have sturdier lift arms and larger connector pins.

There are also variants to the above categories denoted by N, (narrow). These utilize the pin sizes of the listed category, but the width of a category one step lower. The N variations are common in “quick hitches” and allow larger tractors to easily hook onto smaller utility implements.
