johnny, for goodness’ sake, who on earth could have enough zucchini? p.s. Mt. Sg was very curious about your sunflower propulsion thingie. He’s interested in how you keep the bearings from self destructing.
The only bearings in it are the bearings in the leaf blower motor. They are sealed. When the seeds drop in, they hit the impeller blade and get blown out very fast. There isn't any reason for the bearings to go bad. They run just like it was still an electric leaf blower.
