Well, down here in the willamette valley oregon the JD walkers are the only ones that run pretty much UNaltered. Some will run spikes, but they do a good job stock in the ryegrass and fescue here. The Case's all have to be modified somewhat to run grass. They'll run it ok without mods, but not very satisfactorally. I dont know a lot about bluegrass, I think you guys up north grow the majority of it anymore. I would think if you could get a machine to thresh and seperate bluegrass, it should pretty much do any other kind of grass, dont you thinkIJ Do you remember the old Class CS systemIJ It had the main cylinder down front and then a series of smaller cylinders and grates behind it to transport and seperate the material. If I could find one of those somewhat local and in good shape, I think I'd buy it now. The tunability and potential tunability of them in grass would really do well I think. I would think if one could spin the cat rotors slow enough to only use them as seperators they may work fairly well. Perhaps a few home built mods to lessen the aggresion of them for thresh but make them transport faster would do the trick. As you know ryegrass is allmost threshed in the feederhouse

fescue is allmost as easy if its dry but bluegrass may need more, I dont know. I currently run a 1680 with a few mods. This year I installed a set of gorden bars and helical concaves and was able to run the rotor at less than 500rpm. It still threshed and seperated better than the stock specialty, but left the straw in great shape. I had to completly reset the machine as it was a complely different machine to run. The load on the chaffer was so much reduced I had to turn the wind down over 100rpm from where it was with the stock bars and concaves. I'm still fine tuning the thing as it will take a while to get used to it. If you want to you can email me and I'll keep you informed as I find anything around here. Who knows, maybe cat will get into the grass harvesting business someday
