I have lots of diesels around but, it was hard to justify the cost. I almost bought a used one, but in the end I went with a new Grillo 107D with the Honda because it was the best value and I liked the tiller design much better. I also liked the fairly low noise of the Honda.
I would love to have a new 853 diesel, but I just couldn't swallow the cost with the gas Grillo option that is such a capable machine at about half the cost.. Maybe if it was my only tractor, but I have other diesel tractors already. I guess it really depends on how many hours you put on per year, I'm probably around 50 or so.
