I have an X485 with a 62c deck. the left blade is fine but the center and right blades are not cutting even and it looks horrible. I just put a new belt on it and checked the deck and it doesnt appear to be bent or damaged and the blades are installed correctly and the pulleys look fine. I used a JD blade measurement tool and there is an inch to inch and a half difference in the blade from front to back and from left to right on both the center and the right blades. Is there a way that I am unaware of to check out the deck...like I said, it looks fine. Help please!
