The story of the biggest tractor ever built - the 1977 Big Bud. See it... Hear it... Feel it! A 16-cylinder Detroit diesel engine; the biggest injectors ever made; 900 horse power; 130,000 pound weight; 1000 gallon fuel tank; pulls an 80-foot chisel plow and works 60-70 acres an hour! Watch it all work in Montana
