hustler raptor 42

I bought a hustler raptor 42 last year and added the mulching kit and it strips between the 2 blades everytime I mow. It also doesn't clean out under the deck until I hit the end of every row. Ive tried lowering the deck, raising the deck. going at a crawl and going faster nothing seems to help. I've even tried to replace the blades with gator g6 blades and nothing. It also doesn't cut very good where the front tires push down the grass in front of the deck. I am really getting frustrated with it to the point of looking for a different mower. I hate having to mow my whole yard 2 times every time I mow.
