3 pt hitch specs

[paynelea]

I am trying to build some cultivators for sale at an auction using some excess equipment. Is there a source of information somewhere for the dimensions of 3 pt hitches? I am looking for the nominal horizontal dimensions between the lower arms for Cat 1, 2 & 3 hitches. Also looking for the vertical distance from the lower arm mounts to the top link mount on the implement.

Here are some of the specs for 3 pt hitches.

dbHp Spread Mast Height Stud Dia Stud Length to hole
Cat 1 20-45 26.8 18 0.86 1.53
Cat 2 40-100 32.4 19 1.11 1.91
Cat 3 80-225 38 22 1.43 1.91

I hope this table holds together over the wire. There is a whole page of specs in the American Society of Agricultural Engineers Standards if you need more.
