Tons of them used in the Willamete valley Columbia basing and Palouse for just that. We demoed a 8240 in bluegrass and red fescue (don’t raise ryegrass) we struggled with it in bluegrass couldn’t get it to separate (needed rotor block off plates but couldn’t get them in the time we had the demo) but was very happy in fescue. Ran the fan about as low as it would go, I think they had hard thres components in the rotor. I have friends in the willamete valley that run them. I would recommend calling N&S tractor out of Woodbury or Harrisburg Oregon, or JTI out of colfax Washington.
