I came across a mulching blade design today that is new to me. I found them out on a blade rack and they had no identifing marks as to who made them and the dealer couldn't remember who supplied them either. Here's the discription.... They look like a straight highlift blade with a notch cut across through the highlift foil. The upper portion was then twisted to form another cutting edge right there in the foil. It was done in such a way as to cause a downward flow of part of the clippings that hit it and an upper flow of part of the clippings as they are recut by this area. They looked to be very thick steel like a Gator blade. I thought about giving them a try. But they are 125% of what a Gator costs each. I'd hope they'd be good at that price. Anyone else seen these at all???
