Pulled my cdf rotor this afternoon to make some minor changes on the discharge helicals and replace row C bars on the rotor. In this process I noticed something interesting. 2 years ago I installed the partial steep slope helical system on my R75 and at the time replaced row C bars as they were getting worn. Seems like with the standard helicals there is a lot of pressure and wear on the left side of the concave and row C takes the brunt of this wear. I made the mistake of purchasing some bars from shoup as they were less expensive than agco bars and after two seasons they have worn down enough to justify replacement. Actually they were the most expensive due to their short life but that's another story. The interesting thing is how evenly the bars were worn from one end to the other. With the previous helical setup, the left end of the row C bars usually wore considerably more than the right end probably because of all the rethreshing. The soft bars proves to me that the steep slope helicals are doing a more even job of loading the left side of the concave as I would have expected the wear on the soft bars to have been considerable on the left end vs. the right end. The soft bars merely made it possible to observe the benefits of the steep slopes sooner than if better chrome bars had been installed in row C. I believe that without the steep slope helicals, these soft bars would have had a difficult time lasting two seasons as they should have worn the left rasps down nearly flat. Hope this makes some sense.
