This is my fourth year with the tractor (300 hours) and I couldn't manage this hilly 3 acres without it. It had a common deck breakage the first year (covered under warranty). I've had no other problems, I just need to be careful on steep property (tipping with FEL full). I welded up a bucket extension for brush and leaves, (I'm not sure Kubota would approve).
The four wheel drive is great for snow removal. 54" mower and grass catcher works pretty well for picking up mulched leaves. You think you have leaves, we have over 200 oak trees! The ability to dig is ok, not great, we have rocky red clay soil. You just have to go slow.
I added a Land Pride rear blade this year, it works very nice, great for grading roads. The Tractor is a little pricey, or I would have given it a 5 everywhere.
