I'm looking to purchase a RC5615 batwing rotary cutter. I will need the wings to flex down a significant amount to mow over the top of a pond levee with the wings drapped down the sides of the levee. The levee is too steep for me to side hill the tractor and currently I can mow the land side with my zero turn but not the water side. This is just a long way of saying, I need the wings to flex down and cannot find the angle that they will in the spec sheet or the manual. John Deere and Brush Hog brands both say operating angles are 45 up and 22 down. I found a RC5615 I want to pull the trigger on, but I can't find if it flexes down!
