I wanted to go to a farm sale 20yrs ag0, but wife, X then passed now, held me up. I got there just as they sold the good drill. There was another, older McCormick Deering drill that the box was about shot. I got it for $1.50. A friend had bid $1.00. I bid the $1.50 on it. He turned around, saw me, and I saw him, and he let it pass. I got it home, and paid $7,99 for new wood. I replaced the bottom as best I could. Finally, setting outside with tin over it, I replaced the wood again $37.00 this time 4yrs ago. It flows faster from one side than the other. I cant tell it in the yield, but I know its there. Is there a adjustment I can make to slow down one side. I know that theres a cup/flap that has 3 or 4 settings, but I dont know if adjusting them closer might crack the seed, Sudan Grass
