Hey guys, I run a 52" wright stander rapid height with a 19hp kaw. I was wondering if any of you guys use high lift blades for this mower. I seem to have no luck with them as I can't fill the grass catcher completely with the high lift blades. The standard blades pack the grass better for some strange reason. I think they're too heavy for the mower or I could be wrong. Any comments would be great. thanks!
