They do a "Long drawbar" and "Short drawbar" class. Where you extend the bar in our out. You will be surprised on who can make the full pulls. There isn't many on this track. Problem is weight. The Oliver has hardly any weight just to get into the highest weight class on the list. Where a Farmall 560 is fully weighted to max. And can get way more traction over the Oliver with nothing. Now if they did a higher weight class where you can stack it on the Oliver. Then you will really see it pull.missouri massey man said:It worked that time. Sure didn't make a full pull. I'd like to have seen the sled or the hook up. Something was off a bit. That engine is a screamer though.
