I anguished a lot on which rotary cutter to buy with new 4044r. The three choices my dealer offered were JD MX6, Frontier RC2072 or a Bush-Whacker MD72. I ruled out the Frontier as it just looked too light to my eyes. The JD and BW are both rated for 2" material with the JD weighing 1,050 lbs and the BW weighing 1,180 lbs. the blade tip speed was 14,000 for BW vs 17,000 for JD. Cut height ranges were advertised similar. I had decided to spend the extra coin for JD but when I went to pick it up they could not find it or another. I made a haste decision to take the Bush-Whacker since I was planning to use it the next few days and I was almost going with it anyway.
