Sorry for asking what is probably considered a dumb question, but I just don't have the experience yet. I purchased a 2305 this morning that is missing the top link for the rear hitch. I called my local JD dealership and they quoted me a price of $384 for the link. Since a cat 1 top link at Tractor Supply is around $20, I am assuming the JD link is higher quality? Is that it? Do I need the OEM JD link for grading my driveway with a 5' rear blade? Or will a standard cat 1 aftermarket link work? I'm just trying to understand if their is more than meets the eye here. Thanks guy's.
