Last summer I looked at the Meg-Mo blde system out at Louisville. This is the flail type blade mounted on a central disc. I liked the looks of it, but the guy is a fast talker and I hate to commit dollars to what could be a hair brained scheme. I like the idea of four cutting blades per spindle and the fact ahtthey can swing back when they clock something. It's a sizeable investment to set up the first time, having to buy both the hubs and the blades tips themselves.
