Proper angle for middle buster/ripper

[djw250]

I'm rebuilding an old middle buster that I turned into a pretzle a while back, and I'm wondering what the best angle for the plow point is. It was originially at probably about 35 degrees from horizontal when the point was touching the ground, and I personally think it was too flat. I have seen some more modern designs that seem to be much more vertical, but I'm not sure what would work best. I plan to use it mostly for ditching, and I'd like to set it up so I can change points and use it as a subsoiler or trencher. Anybody have any suggestions?

Thanks,
Dave

Here's what works for me and my 21-hp Kubota B7510HST. That's a King Kutter XB middle buster/subsoiler combo. I'm using the middle buster to plow the ground before rototilling (putting in landscaping around the house). Don't know if that's the "proper angle" in the photo but it works for me. In rain-softened ground like we have now here in the North Valley and with the 3pt in float, I can bury the MB deep enough so the lower link arms are almost dragging on the ground.

BTW, the snow-covered peak just visible behind the eucalyptus trees is Mt. Lassen.

I've never seen a middle buster with the point mounted backward like that, but if it works, I suppose it doesn't make such a wide ditch, can you show us a pic of what the ground looks like after you've worked it up before you run the tiller over it, just might be on to something there.

The MB works either way its mounted. I reversed it because the next step in my landscaping chore is to cut trenches for water lines running from the well to the front yard landscaped area. For that job the backward-mounted MB seems to make a better trench with less loose dirt to remove from the trench.
