Size Categories
There are five different hitch sizes, called categories. The higher category hitches have sturdier lift arms and larger connector pins. There is some flexibility in the tractor hp at which one category hitch ends and the next begins.
| Category | Tractor HP | Top Link Pin Diameter | Lift Arm Pin Diameter |
|---|---|---|---|
| 0 | Up to 20 | 5/8 in | 5/8 in |
| 1 | 20 to 45 | 3/4 in | 7/8 in |
| 2 | 40 to 100 | 1 in | 1⅛ in |
| 3 | 80 to 225 | 1¼ in | 1 7/16 in |
| 4 | 180 to 400 and up | 1 3/4 in | 2 in |

Famous quotes containing the words size and/or categories:
“O hideous little bat, the size of snot,
With polyhedral eye and shabby clothes,”
—Karl Shapiro (b. 1913)
“All cultural change reduces itself to a difference of categories. All revolutions, whether in the sciences or world history, occur merely because spirit has changed its categories in order to understand and examine what belongs to it, in order to possess and grasp itself in a truer, deeper, more intimate and unified manner.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
