I use my 20qt Hobart for everything. Grinding, mixing, veg prep, etc. It’s a tank. Very low maintenance, easy to clean and sanitize. Spend a little extra, get the attachments, you can’t go wrong.

Parksider I Have mixed 25# batches in mine, just start slow (#1) and increase speed when meat block starts to adhere. Make sure to turn unit off before switching speeds, can’t remember the number of “write-ups” and reprimands I have given for ‘speed shifting’. They do make a “collar” for the bowl to keep the product from spilling out, it is used primarily for liquids and batters, but could be used for anything. I have a stainless bowl, adds a little weight, but chills in the cooler great. I use the paddle for mixing, good protein extraction, and easy cleanup. A 20qt runs on 110, but you will need a 20A circuit, I have one dedicated to the mixer. Floor model or stand model? If stand model and you are going to use the grinder or any of the powerhead attachments, a stand of the proper height is important. I put my lug on a wheeled cart and grind or shred away. I have a stainless stand w/ undershelf for attachments. Heavy unit, you are not going to want to move it every time. You should be able to find most of the extras on C-list, eBay or local auction sites, unfortunately, restaurants go out of business every day
, their loss, your gain. Good luck!
