Ariens zero turn

Ariens edge.. 6 hrs...as new , used 3 times and the blades have hit nothing but grass, bought from healys last summer but change of circumstances dictate sale. Has the mulching kit on it. I have the side discharge unit and blades which are unused, I have the manual and original receipt from healys for new owner. I paid 6k for this machine and its a great machine to use and also very comfortable(read the reviews) i then paid 400 for the mulching kit so it stands me 6,400 Looking for 5,500 for it,
