March of 2018 we installed new disc openers and valion seed tube guards on our Kinze 12-30 2200 planter. March of 19 we thought that we would not need to change any parts. He found a line of hard dirt on all the disk openers. The valions had a worn groove that matched the dirt ridge. The planter only ran on 960 acres. We were expecting several thousand acres before another rebuild. What went wrong? How do we avoid the problem for 2019. Of course when calling the company we were told, "I've never heard of that".
