Thanks for pointing that out. I went back to take a closer look. Now I see the difference between low and high wire grate floors too. We have a 1990 R50(R5055) Hawk series s_n 3158 with low wire floor. Before removing the rotor I measured the clearance between rotor and cage, I found 1". The height of a rotor rasp bar is 1 1_4" by 2 1_4" wide, the spacing between grate bars is 1 1_2". I cut 1_2" from each side of wide spaced (corn) bars.(Grind off the chrome where you intend to cut with a torch) When dropped in place the height is now 5_8" above floor level. I seriously doubt this plan would work with a high wire grate. I don'tknow how far down the wire is below floor level. If it's 1_4" the result, my best guess, would be 0" clearance. A P1 reverse wide space rotor bar(new rasp height is 3_4" or less) cut to fit might be a better idea. I also took a closer look at the first picture on page 1 of the thresher grate. Notice the kernals of corn wedged between the rasps. Correct me if I'm wrong but that looks like a standard 7_16" spacing. In that case, even all forward bars can act like they're worn flat. Kinda like the difference between snow tread and highway tread driving in snow, when the tread is full, the tire's bald. I hope this helps.
