Thang bout a hammermill, is the clog up REAL easy. Specially if you don't have a horse of a tractor running them. One they clog, youll know it right away. The belt will throw off the pulley, or the tractor will die. If its being run by a puny tractor, the tractor will die. Whichever, when that happens, YOU GOT A MESS to clean out. Don't usually happen with grain, but it can with corn. It SURE can with hay. ASK ME N O T HOW I KNOW. lol. I usta take flakes of hay, and put the corners in till the flake got small enough I could put it all in. When it went ALL in, it let the tractor know it had better wake up, and that's a big CC Case. I finally realized why they made the trough/tray as long as they did. It was to keep most people from being able to stick their hands in the mill standing behind it, But dummy me, Ive had it plugged, and went to the side and gave it a shove, flat handed. NEVER want to hold onto something, at that point, cause it can whisk in there in a millisecond, when its been plugged for a minute, not doing anything.
ALSO, IF your using a belt, you want to know which way the mill is supposed to turn. DONT ASK lol.
When I used to fire it up, I always wondered what the neighbors thought I was doing down here.
