Nice dozer! My friend just sold his JD450C and bought a skidsteer instead. The dozer was great when building his house but a skidsteer is more useful for small stuff. Plowing snow with a dozer is....well....a little overkill I guess! Nice yours works on that trailer - we never had the ability to tow his around as it weighed about 20K with the backhoe on it.
Love the storage/barn. I could use one of those for my poor trailers (2) skidsteer (1) plus attachments, dirt bikes (3), TC's (2, though one is just a shell now) and other assorted junk I have that is pretty much all stored outside at 8400' mountains in Colorado. My stuff gets some harsh weather. If my dad taught me that lesson it was about not having any stuff as we had no garage and so had no extra vehicles! If it didn't fit in the basement I guess we didn't have it. :)
