I agree with RichardInKy. This is an eating machine! It really does take at least a good hour to bolt all the parts on this thing, and what really perturbed me was the inability to access the oil filler after the machine was finally put together. The manual says that the tall oil filler is an accessoriy as are the side oil dip sticks, but I can't find them anywhere. Another migraine came along when one of the outward hopper bolts broke right off into my socket bit. I'm going to try to flatten it out with a hack saw and then drill through it to create something that will help me to rebolt that area. It was too much trouble to call Sears after we had just put the thing together. One broken bolt can be fixed with some imagination I suppose, but the darn thing should have never broken off so easily. GR-R-R! The Briggs & Stratton engine started right up the very first time and took care of a half-acre (so far) of brush in a flash. This thing feeds itself as long as you guide the branches a bit while pushing them into the hopper. As for the shredder, don't put wet leaves in as it will clog the machine. Other than that, this is a very sturdy, well-built machine that we hope to have for a long time to come.
