Here is my almost complete homemade leaf vacuum. Still needs a mower deck to engine hose but otherwise complete. I fabricated the frame, bought a new 7 hp engine from Tractor supply, salvaged an old aluminum leaf vac blower and hopper that needed extensive work. Hopper tilts and self locks the gate when the hopper is dropped back down. I built a lever at the front of the hopper to release and tip the hopper. I decided to make it a 3pt hitch attachment instead of a trailer for a couple reasons. First, I don't have to worry about tires going flat and second, the vacuum trails behind me perfect so I don't have to worry about backing up a short trailer. Total cost was around $300.
