Hi Thanks for the advice. What should I do, put half height cylinder bars in, or just put the regular forward bars in place of the reverse barsIJ Which would you recommendIJ Keep in mind this is for soybeans, wheat and corn. We are not afraid of a little bit of work to set the machine up to do the best job it can. These half height bars, are they forward bars or reverse barsIJ How much are theyIJ Do they come as a balanced pairIJ As well we heard of some guys shimming the helical bars out with washers, is this a good ideaIJ Thanks for any advice.
