Some rotary cutters come with brush blades and some come with lift type blades , my Bush Hog Sqealer came with straight blades and left a poor cut in grass, I changed the blades to lift type blades and it made a huge difference , one other thing I did was cut some conveyor belt and put on my mower instead of chains to keep things from flying out from under it, it seemed to improve the cut even more as I believe it created almost a vacuum like a lawn mower deck does , so yes you can get a good cut and lift some of that mashed down grass with the right setup on a rotary mower.
