I attend a few pulls a year and am wanting to get involved in helping out at a local pull and would like some advice on how tractor are chosen to pull in the "plow" classes. At some pulls a 350 international has to pull against an sc case, in the 2 bottom classes. I can understand the sc being a 2 bottom but not the 350. I also see the 560s pulling in 4 plow classes but when the 560 come out it was advertised as the "most powerful row crop tractor capable of pulling 5 bottoms."
These are just a few of the instances that I can think of. Is there a list of which tractor was advertised to pull in which class anywhere? Or do different areas pull differently.
I was trying to think of a equation that would be accurate for most tractors. Right now the most accurate thing I can come up with is 1 horsepower per plow inch. For instance the sc case was designed to pull 2-12" plows. So 2(12)=24 and the sc had 24 horse. This works pretty well with the row crop tractors all the way up to the 4020 which was 96 horse or capable of pulling 6-16".
The only problem I can see right now are with the standard tractors. The have a lot more weight than the row crops but usually not as much horse. Short of dynoing every tractor at the pull what is the best way to determine which plow class a tractor should pull in.

plow classes are a joke unless you weight them to keep them half way honest. you will have some old boy slip in there with fluid in his tires and be about a thousand lb. heavier than everbody else

I have never heard of a pulling plow class. Is this like a plowing match? I have a Super A the puts out 25hp and I pull a 2/12 plow in a plowing match every summer in Big Rock IL.

one club I know of that uses plow classes uses the 'honor' system. (MM U in the 3 bottom class, MM G in the 4 and so on). The system they use to keep people honest is that if you win two times in a row (win the 3 bottom class one week and win the 3 bottom class again at the next pull you attend) you must move up to the next class. I don't know if you stay in that class the rest of the year or not, but it keeps the U's (or like size tractors) out of the two bottom class.

The only way to get close is to get a book of all tractors(like an encopedia I know its not spelled right but close to me!) that list info.on most tractor and usally list plow rating. I would love to see a 96hp 4020 pull a 6-16 Our 4230 stock pulls 5-16 and all its want for an all day duty.
