I am a big fan of the speed limit rule and tire limitations. I love the way Brad Peters runs his events and look at the turn out!
3.5 no cut, saftey rpm limit, agriculture motor that is of the same make of the tractor
5.5 any cut "
Open with same as above.
People end up where they belong some drop into a lower class, but the speed limit makes balances it out in my opinion espically with a even transfer pan (no drop pans).
