:welcome: to TBN
Can you tell us more about your request.. add in some details for guidance and what 855 attachments you have now that maybe don't work on the 4410?
Would help to know what you call a "tiller".
I use a John Deere 660 with my 4410. Just be careful how you compare tillers. Some come with 4 tines per spider and some come with 6. Some are also built a lot heavier than others. I've worn out 4 sets of tines since I bought the tiller new in 2004.
Great, now where are the pics... to go along with the thread title...
