Previously owned a GT245 with a Mulching Deck for 19 years. The machine worked perfectly. Bought a new X590 with an Accel Mulching Deck that does not Mulch. Had it back to the point of purchase ( James River in Danville, Va. and they tried several different things yet I am still having to cut my Grass 2x's due to the new deck just doesn't mulch Correctly. I'd like to have someone from JohnDeere call me. someone from John Deere User's recommendation: Dont Buy until they fix the accel deck.
