We process most all of our own game meat. We had acquired an 'older' model (1960)grinder and had been using it for several years. It has always been a little challenging to get it all done. Well we bit the bullet, so to speak and went to Alaska Butcher Supplies for help. I thought that we were going to have to get a new grinder, thinking that they were going to tell us that we were not able to get parts for the old one. One of the first things they asked was when the blade and cutter were last replaced. As far as we knew they were never replaced, just sharpened once in a while. Well we bought a complete set of NEW blades and WOW what a big difference they made. We ground and packaged 80lbs in a hour! We were very surprised and happy.
So, if anyone as grinding their own game meat, and your blades/cutters have not been replaced for a while. check them out. It might make a big difference!
