The massive model 4300 tractor was International's entry into the large four-wheel drive market. The tractor was built by Hough (manufacturer of the Pay Loader) and the final design was influenced by a desire to be larger than the John Deere 8010. Unfortunately for International, the 4300 was "too big, too soon" and production was limited.
