If you do 5 gal buckets, this is a great way to get them where they need to go and save your back. I had found some garbage can wheels . Needed something to nest my bucket in so it would stay on. Used 5 gal pot saucer. Screwed on and we’re rollin. I’ve had to recover from 3 hernias and really don’t like help. The only assistant I trust is my microbes.
