thanks for the info on the case, but after reading the rules and regs for the club my son will be pulling with, decided to look for a smaller tractor for him to start with. came across a craftsman frame and a 12hp ohv engine that i will build into puller. dont know anything about the freme yet and as soon as i can figure out how to put pics in this post i will add them. its an older frame, dont think its a suburban, but fingers are crossed. will probably run with stock trans, but have read that a cub trans is better, so will start lokking into that for future pulls. any info on this would be great, for again this is all new to me. again my son and i appreiciate all the info given.
