building what you want, from what you can find... commendable, and this mini dozer from a lawn mowing Cub Cadet is great

They were built by International Harvester, but they also had about 101 other attachments. They were over-engineered to the point of being indestructible. Cast iron Kohler engines, cast iron transaxles, and very little plastic makes them highly desirable now.

The even number Cub Cadet models were mechanically driven, the odd numbers were hydros.

Dan took his circa 1963 Cub Cadet 100 and decided it would make a sweet crawler tractor. It looks like something the factory would have turned out. He had to make clutches and controls to steer this baby, just like the early Caterpillar tractors.
