Nice write up on a a cheap chinese attachment. I agree these attachments have their place as long as the buyer understands what they are buying. For mobile concrete mixing for grouting manholes and pouring inverts is a concrete mixer bolted on the rear of our dump trailer. Dump a CY or 2 of sand in the front, slide the pallet of cement behind the mixer and we have a plastic tote we can pressurize for water. Works pretty well and we made a pintle hitch fork attachment to move it around with a skid steer.
