I have a TC33 but was wondering, never had owned one of the older models like 1620, 1920, 1710, (I think those are right model numbers), were these tractors more dependable and better built then the new Boomer TC models? I really like the old look with the white fenders and more square front ends. I know they make the TC30 which has the older look but would like to know which one was or is better??????
