I used the stump bucket for 5 minutes and blew one of the loader bucket cylinder piston packings. I have the approved Mahindra 7520 package - factory installed 275 FEL so it will be covered under warrantee. They are aware of the problem and have a design update to correct it.
In the short time I used it I could tell that you could fairly quickly make progress but only in small bites. The gist of it is that you cant push far. You are essentially pushing a prism with one open side into the ground. The wedge effect is bad enuff, but with low attack angle the backplate hits quickly and you are definitely stopped. So you try a higher attack angle and the heavy hydraulic loading under push pops a bucket cylinder. I didnt get a chance to learn any finesse, but I can tell this item can be a powerful tool. A 6" oak stump next to the 18" pine was not even felt. Good sized roots were coming out with each pass. You just have to figure out where to nibble next. You cant get much dirt in the bucket because of its small mouth. Im guessing some refinement is in order, but not near ready to decide on what. Ill post again after Ive used it a bit. First the loader cylinders!
