i called them last week, the guy i talked to didn't know much so he sent me some literature and a video. The video only showed their trailer that they make for dumping grass. Price for my 60" deck was 140$. They don't recomend resharpening the blades but to buy new when they get dull for $3.50 each. So, instead of resharpening it woulkd cost $31.50 each time they get dull. Also, it doesn't look like there is any lift on them.
I think I'll stick to my MEG MO blades, instead of a copy cat design.
