No more vaccum

Hello, I have a John Deere LA135 that no longer vacuums grass, the chute continually plugs, even after a belt change, new blade and under deck scraping. Always had an issue but has gotten worse. It also does a terrible job on mulching, just leave a trail of chunky grass. Thoughts?

What are you running for blades? This time of year can be difficult to bag. Slow down, raise the deck up a bit or cut while discharging, let the grass sit and dry out a bit and then go back over it bagging.
