I guess I am mostly Cubs. If not because of loyalty because it's practical. I like having a bunch of tractors that have many of the same parts, functions, etc. I understand differences between models but I like common, practical stuff. I like steel over plastic, at least where it counts, frames, shafts, brackets, etc. Cyclops plastic doesn't bother me, they still have the humongous frame. The old seats on the 70s are a little harder to take over the nice padded ones. I don't have a bunch of different parts for a bunch of different tractors. It's easier for me to have a PTO clutch that will fit more than one tractor. Trans fluid that is good for many. I just priced the fluid for my 2186 yesterday and it was twice the cost of Hytran. The 2186 and 1554 are not nearly the tractors that my others are. I'm not sure I would buy a new Cub.
Truth be told, if the first tractor I spotted sitting in that yard 25 years ago would have been green I would probably own 8 or 9 of the green ones. I guess I don't change very easy. I'm not sure if that's loyalty or stupidity.
