Could be either deck pitch (front is higher than back), or rounded off corners of your blades...probably your blades needed to be replaced. Check them.
Hope that helps.

Is this an actual whole mulching kit on this, or is it just a plate over the discharge? If that is all it is, then that will give you just a bunch of clumped up grass under the right side of the deck. The same thing happens when you close an OCDC and try to mow with it. All the grass is blown over to the right side of the deck, but then stays there. With a mulching kit, the grass stays in the individual, seperate chambers or bays. If you were side dicharging, then we could go on to something else - like a blade issue or something. While we're on this subject, I had something similar to this happen with my older Gravely Promaster rider. I was geting anarrow streak of grass being left right at the edgeline of the discharge chute. It would only form toward the rear of the discharge, of course. After watching and studying it carefully in different types and lengths of grass (one person cutting slowly while another walking beside watching), we realized what it was doing. It was sucking a portion of the discharging grass back INTO the discharge chute, and dropping it, leaving the line. These discharge chutes are extremely wide on the machines, and you can see that part of the sweep of the blade as it goes back in is somewhat exposed. I ended up going with a blade with a bit less vacuum, and it cured the problem. I realize this may be irrelevent to your situation, but I just thought while we were on this subject I'd just mention it for anyone else's interest, as well.
