I wholeheartedly echo the last post. This machine was designed by an idiot with a sadistic bent. The motor has to be assembled atop two spindly legs while lying on its side and the motor mount and the leg assembly are not the same width, so some intense jury-rigging and struggle is needed to put the two together. The biggest joke is the leaf slot--no wider than a mailbox, so just tiny handfuls of very dry leaves fit, even with the "pusher". And, don't get any sort of rhythm going with this tedious process, because it will clog at a moment's notice. Not meant for a yard full of leaves! It does chew up branches through a separate slot OK, but often leaves little half-chewed stubs that rattle through the machine for 5 minutes or longer until it finally spits them out.
