Locality, locality, locality.
My package in my sig was 11.5.
So far I've dumped about $200 into chains and hooks.
For real price comparisons check
Used Kubota Tractors and sold prices at auctions.
Also - what are the parts worth to YOU?
I don't plan on mowing, I needed a box blade, backhoe, trailer,bush hog, PHD, grapple, 24 HP tractor.
Still have to get the backhoe, bush hog, grapple and PHD. A MMM would have been useless, seeders, tillers, subsoil plows are useless to me. I would have to sell a finishing mower.
So when buying used plan what you know you need.
Also - sounds like you are working with a dealer - what's the support likely to be?
My package I paid for what I hauled, no support envisioned.
Good luck!
