Anybody try these grass kits for a 575 NH baler

  Has anybody tried these grass kits that New Holland has available one is a grass hay feeder kit #9861696 I see where it might help in short hay and the other one a left hand feeder wedge #9849260 says it works in medium to large windrows,I cant see how it will help unless it restricts some of the hay going into the chamber I hate to spend the money and not work HERE Mike 10 have yall installed any up there? All we have here is grass hay no alfalfa. Ford had a kit that went into the bottom of the feeder floor so the rotor could catch it better and move it to the other side better never heard anything about them. Hope somebody has seen these work
