I was wondering if Case still has parts for the model 56 corn planter. I tried looking up the model number on Messicks site but couldn't get the corn planter to come up. I've seen a couple listed cheap as parts coming up. They look like they could be useable but can't tell with out a visit and the fertilizer parts are the big mystery. I know they have been around a long time but a lot less time than the planter I currently have which needs a rope to raise the markers. Planter I have works but lifting the markers is a pain and since I only plant 3-4 acres a year can't justify big bucks on another planter just to get markers that lift when the planter is raised.
