I have a chance to upgrade to used 6' KK tiller. The tiller was just bought this spring and I was told it was used to till about 50 acres. I currently have a 5' KK tiller that I have had for 4 years and I don't have 50 acres tilled with mine. To me, 50 acres seems like a lot. Is 50 acres a lot to have on a tiller? Chime in if you have a tiller and let us know what you think you have for acres tilled with it.
