I'm considering getting out of the Stone Age with my old tractors trying to figure what might be the best option. I have had several D7s. E, F and G over the years. They've all been good machines. that old school stuff is really all I know. I do General work of all sorts. Once in awhile a pond but mostly forestry roads and just general country work. Driveways land clearing Etc. I'm thinking of getting rid of my D6 C and D 7 e and getting one somewhat newer tractor to take place of both of them. A D6N looks like it would be a good fit. In the past six way blades just didn't hold up the forestry work. But the newer ones look like they are built pretty heavy. What might be the best General application Dozer for me. What is the difference between a d6m and the d6n? And what are the pros and cons? What a d6k be better? But I don't think I want or can spend that much money. And any other suggestions would be good. I don't want an LGP. Thank you
