Mid Mount Mower Deck Help

[smullen17]

I have a B8200 with a RCB60-1 60" mid mount mower. When cutting, the deck leaves a trail of grass down the left side (opposite side of discharge chute). This is my first year with the tractor, put new blades and belts on the deck. Underneath deck is clean. Is this something inherent with these decks? Any help suggestions appreciated. Thanks, Steve

Are all the anti-scalp wheels set to the same equal height?
