Looking into pulling a massey 44 standard in div 2 3mph class. Tractor has 14.9x 30 rears with cast centers and 6.50-16 fronts pressed steel. Will remove pto and belt pully drive. What can a standard front axle 44 get down to? Still need to build weight brackets wheelie bars and hitch. The club I will be pulling with allows the 44 to start at 5000lbs. Is this obtainable with the cast centers on rear? Also it is a bone stock fresh rebuilt motor in it, will this do ok in 5000, and 5500 lb class 3 mph? Or should I just stop looking at this route and find a different way to go to get back into pulling?
