I have a 2009 Polaris 550 XP EPS. I tried to remove the seat and It won’t come off. I pulled up from the back of the seat and the first 6 to 8 inches of the seat seemed to flex and to be loose. But the rest of the seat did not budge. I am afraid to pull any harder I don’t want to break it. Are there any fasteners that I need to remove?
