Having coffee this morning and watching the sun rise over my heavily frosted garden, I decided today was the day to till it under. I considered using the plow, but really liked how the tiller does it all with only one implement hook up and basically no adjustments. So I swung by the local rental yard and scored the same tiller for $65, which is pretty reasonable for 9:30 AM Saturday until "any time before 5PM on Monday".
It sure made short work of the garden. It's easy to understand why I haven't seen any decent used ones come up for sale locally. I wouldn't sell mine if I had one either.
Maybe after Thanksgiving I'll start looking for a dealer with a leftover to move.
