D9 cable dozer - Heritage Machines
The D9 was a series of heavy, tracked-type tractors, carried on continuous tracks and usually used as bulldozers. The series began in 1954, with a prototype tractor called the D9X. Ten D9X prototype models were built in 1954. Then, in 1955, the 286hp D9 was introduced to compete against the more powerful Euclid TC-12.
