Thank you for the replies. My tractor width on rear tires is also 63". I have a HST also and I was mainly concerned with the performance of a larger tiller. It sounds like a 60" tiller would be fine if I go slowly. Are there any tillers I should stay away from?
I'm looking to buy a rototiller for my CK2610 but haven't been able to find good info on what would work well. I don't want to buy something that my tractor will struggle to pull. If you can help with weight, width, and overall performance I would be grateful.
