Who said ONLY a mini? I would use my tractor for rapid material movement, and I would use my mini for rapid material extraction. At the same time my tractor would have a rake or box blade on it and excel at it at the same time.
I never said don't get a tractor, I think most people should start with a tractor. I also never said don't get a bh. Based on my experience, I would say it is a small window of users that the 10K is well spent on, that is all. The bottom end would be better off renting, the top end would be better of with a mini.
I guess you all missed the Andrew reference. Your backhoe is the handiest tool you will ever own.... right up until you have an excavator, loader etc. Once you have those the backhoe sits and collects rust.
My mini has a 25HP Yanmar in it, I can pick my tractor up with it. The BH77 (the bh that would fit my tractor) doesn't come close to it in ANY category. Depth, force, lift capacity etc etc. not even close by half. Production on the mini is on another scale compared to anything backward facing with stabilizers.
