I miss the old days when the tractors were pretty much stock other than the M&W, etc kits put in them. There were no cut tires, aftermarket this and that, and properly tuned tractors and track reading lead to success. Having pulled since 1988, I went forward with some mods as time went on, but never sunk a huge investment in a engine, seeing others break or take unnecessary money away from my family. I remember a gentleman that applied and got several credit cards and maxed them all out building engines for more than one tractor, and just made the minimum payment.. lol. To each his own, but I always could not see the point in spending x amount to just obtain trophies or measly payouts. I kinda retired from it for the most part around 2001, and still pull but probably attend 6 or fewer pulls a season, because now my kids are older and require my support at sports, etc. I took home more than enough hardware thru the years beating some of these "million dollar babies" because the owners had the cash, but didnt have enough sense about reading tracks, weight balance, etc. You cant condemn people that have the means to buy/build these powerhouses of today, but in the early days, there were tons of people around here involved, all would come out have fun, some were old friends, and many new friends were made. Kinda like fellowship more than cutting each others throat. As prices to compete rose, and attitudes became crap, most went another direction and found new hobbies. Now its complaining, whining, etc, about each and everything at any pull. The days of going over a buds house and put a tractor together or help them with equipment problems at a pull itself, have turned into mostly snarly guys that show up, with no expressions, have their 45,000 pickups with color coordinated trailers, and their 20,000+ machine, jabbing at other brands, not even knowing anything about or appreciating the tractor or brand they have. there was a core of us, some my family and close friends that probably represented 40+ people and maybe 60 tractors. We for the most, part ran the circuit together, convoyed together, ate out afterwards, etc. Out of those 40+, maybe 5-10 still pull some or run the local circuit. Im really not trying to sound like Im bashing the current trend, but those were some great days in my life and a lot of fun, but you cant go back.. so I just pull when I can now, or if I want, and even my outdated stuff hangs in there still. As far as the last part of your question, in the days of non cut tires, and no stroking, Allis was tough in light classes, medium classes - Farmalls, JD's Olivers, molines were all competetive, heavy classes were ruled by slow tractors, JD A's, Cockshutts, and 60JDs that were 52 models. In those days, the tractors were seperated - 1939 and older, and 1940-1952. Anything newer? nope couldnt pull.
