I just removed the mulching kit from my exmark and reinstalled the ultra vac and no longer need the kit. I purchased it brand new in December from the stealer for 256 plus tax. It has been used on about 12 yards to mulch leaves. Has new mulching blades, used one time. Still have the original box it came in and all hardware and instructions. The part number is MK483Q. My hp has the 48" deck. Selling for $135.
