You're right, my math was faulty, $2400, not $3400. The Deere tiller is a lot of bucks, if you do a search in the attachments forum you'll see many threads on tillers. Howse is one company mentioned that makes a good tiller for a lot less $$$.
I have a cheapie 5ft blade on my 2210....$249 scratch and dent special...and after $10 in spray paint it looks good and worked great this winter plowing snow. Right now I have a small tiller on my 335 but when I replace it with one for the 2210, it probably won't be a Deere - too much $$$ for a device I use 1-2 weekends a year.
