Sorry to revive an old thread but I am a new owner of a JD 4500 with about 2675 hours and was looking to purchase the adjustable draft links to make it easier to swap between my rotary mower and chain harrow. Based on other's experiences from reading some of the posts, I was hoping they would cost around $200-$300 for the set. I asked my dealer and all he could come up with was a listing for the right and left sides individually (LVA10608 and LVA10609) at $850 EACH!! Even on-line, the best I could find was $650 each so $1,300 for the pair. Am I missing something? Any ideas for me? I am new to this so I appreciate any help.
