ok so i want to get into racing mowers, and i went to letsmow.com and printed off those rules. my problem is they didnt seem very detailed. it seemed as if those were just updates. where do i need to go to get a detailed set of rules with all the do's and don'ts? like legal measurements and all that kind of stuff. am i to start in a certain class? there just seemed to be alot of info missing, any help would be great, thank
