I am putting in a driveway. Had to dig out the topsoil/roots. I didn't have a box blade (and have never used one before) but had a single ripping tooth which worked OK to tear up the roots and get everything nice and loosened up. I wanted a box blade - thought it was one of those essential implements - but had a hard time finding one. Online was all back -ordered. Used ones, what few there were, were ridiculously priced almost as much as new ones for rusty old hulks. Finally I went to my JD dealer and he had a 48" sitting out back for a descent price so I brought it home. And I have been thoroughly disappointed. I'm sorry I bought it. I wanted it to smooth out the dirt/sand to level prior to putting gravel and pavers down. But it does not work well. It digs in when you don't want it to or comes up too high. You can't put any down force if needed, only gravity. I tried it twice now and quickly reverted to using my FEL bucket. I quickly became a master with that and smoothed that driveway out nicely. You can really fine-tune with that by varying the bucket angle and down force. Now I think my box blade will sit out back and not get used. Wondering if anyone else feels the same.
I guess it would work for smoothing out an old gravel driveway, but can't think of much else, and certainly not this project. Thought it would be more useful.
