TC-30hst , loader and tiller 20K sounds very high,
first off you can shop on the web for prices on all brands on tractors and implements, there are packages galore, get a base line on pricing then find local dealers to check out feel and fit. I would stay in the 60" rear wheel track group, close to 30 hp range. I have a TC-30, gear, loader, King Kutter tiller plus a few more implements. Close to 300 flawless hours this is its 4th summer, there is a lot of very good tractors in that group. I was just partial to blue at that point.
mine in 2003 TC-30 gear, 7308 loader, KK 60" tiller < 16K
plus 1K for hst, 17K, plus 3 years worth of inflation.
people will say that dealer support is very important, especially for first time tractor owners like me. I bought some rear remotes and filters, fluids only so far. Either it is a very good tractor or I'm very lucky, Naw it must be the tractor.
