Has anyone "upgraded" to the newer Accel Deep mower deck from the old Edge Xtra deck? I have a 2012 x534. I like mulching, when conditions permit because I don't have to worry where clippings get thrown and I can mow around trees/obstacles in any direction. (I have a lot of trees) Taking the mulch kit on and off is a PITA which generally requires dropping the deck to get it on and off. Fine once or twice a season, but not every few weeks. From what I've read, the Accel Deep is a direct fit to the older X series machines. List price looks to be about $1200 or so, plus the mulch control kit. Guessing I can get around $500 for selling my current 54" deck and mulch kit. I'm curious if anyone has done this, and if they think it's worth the money. Thanks!
