Here we go it's winter time. You blew it with just one rule 3x3 turbo. What farm tractor ran that big of a turbo ? Heck it even takes the SF class to get to 3x3. No such thing as farm stock that I have seen in the last 10 years. Your rules do line up with what is called farm stock in our area of Pa..

Put it on the pto dyno, make sure the pto runs at least the correct no load speed, (600ish for 540, 1100ish for 1000) pull it down to rated speed and hold it there long enough to make sure it's not going to self destruct. Disregard the horsepower number it's making.

Let anything go as far as turbo's, engine swaps, ect is concerned. If it's legit able to be run at full load all day without hurting itself, it's a farm tractor.

If the puller/owner requests that you let off the dyno, he's out.

Factory stock would be a different story.

Farm stock. Unhook it from the manure spreader, turn the screw and go pulling.

I have been involved in all kinds of motorsports and the bigger the rule book the more it costs.I pulled when people stepped on the sled for weight[speed limit] and 200H.P.was a lot and it was fun.It seems as things evolved, the price to play went up, and fun level went down. Run what u brung and hope that's enough doesn't work either but tech doesn't take long.Merry Christmas!

You can have all the rules in the world the problem I see a lot is enforcement.so speed limits is the best way I see to have a farm stock class. Just my 2. Cents

Anytime you use the word farm stock you open a major can of worms.
