I don't think plugging will be a problem, digging in very easy sandy loam soil. I am thinking that if I use a smaller bucket, can have one person on the tractor, me on the backhoe and almost dig at the tractor moves, it's that easy and fast...
I went and measured my bucket, it's an 18, not a 12, sorry for the confusion. Doesn't Kioti sell a 9 inch?
So far, I love the backhoe with one exception, it needs more reach (spend as much time moving the tractor as digging), but then it's a small backhoe, didn't expect much more.
On the other hand, I saw a BX series Kubota with a backhoe. I can't imagine that thing would be any more useful than a good shovel, and a **** of a lot more expensive...
