Sorry, I'm not up on the terminology, I googled bucket types and the closest thing to what I'm looking for was called a sand bucket.
I was thinking light duty since I'd only be scooping muck, hence was hoping the BX could handle a 24" bucket. Aluminum even perhaps? I'll search for the old post you mentioned rayco.
Best solution is probably to bite the bullet and rent a mini excavator for a few very long days. I suppose a tractor backhoe set-up is impractical b/c there is no way to scoot along sideways. Great for making a ditch, terrible for maintaining one, unless it's narrow enough to straddle. Thanks for your help guys.
