My dad and I started a tractor pull in our town a year ago and we have a lot of local boys pull their old parade tractors and some have modifieds. I pull a '41 A JD, 4030 JD and next year I think Ill pull the 4430. It might be too heavy though. Its alot of fun watchin them old tractors pull. I wish we could start pullin semis, that would be sweet! I love watchin them pull, they sound pretty good when they start bellerin under load. Lots of black smoke! Any of you out there pulled semis or watched em before?
