I bought a used B2650 with 200 hours on it. I am having issues with the mount of the mower. If i hook up the mower the way the book says the front linkage will lift the front on the mower deck off the ground and that is with the front link arm extended as far as it will go. It needs about another 1/2 to be right if not more but the front link is extended all the way.
