I don't know what the old tires looked like, but I've been tractor pulling for going on 23 years now. I've never had good luck with new tires. The rubber is just too soft, the bars will just curl over and you lose traction. But I wish you luck. 💯
First the H, then the Super H, then the Farmall 300, then the Farmall 350. The engine bore was increased with each model. The 300 Utility was a clean sheet design. The W-4 and Super W-4 that preceded it are standard tractors and the 300 is a redesigned utility tractor. This increased the versatility of the tractor and therefore the sales. Although the Super H and Farmall 300 were both produced about 2 years each, they had similar production numbers. The 300 Utility outsold the Super W-4 several times because of its versatility, but some did not see the 300 Utility as a true replacement for the W-4 series. But when the 350 Utility was introduced, IH offered a package for mainly for Western Canadian W-4 customers. Those tractors had wide crown fenders that covered the tires, a full platform, updraft exhaust, and a rear auxiliary fuel tank. These were known as the 350 Wheatland Special. This package was also available on 460 utility tractors and they are known as the 460 Wheatland.
