@LouieDN You can split the main case open and get to the eccentric crank, split it apart and emory cloth it clean. Fertilizer, moisture get in there and make a rusty mess. Also, after it works, go buy a different kind.
@chumlykokesh @cullenjwilson Pull the big air supply hose off between the fan and CCS tanks and look in the manifold, sometimes mice like to party in there.
This is may be a long shot but does anybody need a full-time summer intern in their ag-related field? I have a student whose placement fell through due to COVID and needs something for the summer. Agronomy and livestock experience but is very interested in commodity marketing.
