This yard vacuum machine has a 6 hp Briggs & Stratton engine which fires up easy enough and runs ok . It is designed to suck up, shred, and deposit leaves in the rear bag. It also has a wood chipper for small branches. Works pretty good for what it’s designed to do. It will also vacuum Pine needles up. It is not self-propelled. The bag does have a couple holes in it, but I just put clamps to seal them up. You don’t even have to do that as it self-seals the holes once it starts sucking up the leaves. Available for pick up in Charlton.
