Way back in the 1960's Howards made a similar thing called the "Haytimer". It was not in production very long and I know why! We had one for about 2 seasons before we traded it in for a Fahr drum mower. Believe me, cutting hay with a flail mower is NOT a good idea, especially if it rains after the hay was cut. I seem to remember my dad calling it "The hay destroyer".
