I own the 1.5 hp grinder it's heavy I'll tell you that! I used it to grind up and produce 75lbs of burger! I had my 7 year old helping and even she could do it! The grinder grinds faster than you can feed it so be ready when you start.. I cut the meat in 2x2 strips when the meat was to big for the opening… I would also suggest keeping the fat in larger chunks it seems to work with them better.. Everything worked great and clean up was super fast! This is going to handle anything a private or small operation can throw at it!
