John Deere 520 530 clutch belt pulley B3760R. We have lots of new, used, and rebuilt parts available the following John Deere models: A, B, D, G, H, M, R, 320, 330, 40, 420, 430, 50, 520, 530, 60, 620, 630, 70, 720, 730, 80, 820, and 830. We try our best to describe EVERY part accurately. We will not describe something as “rebuilt” or “re-manufactured” just because something has a couple new or shiny parts. If we describe it as rebuilt, we will have done it, had it done, or be sure it was actually rebuilt. The parts we sell are usable and in nice shape unless otherwise noted in the description. About us: We repair, restore, and use John Deere two cylinder and new generation tractors. We take pride in what we sell, whether it is a part or a tractor. Thank you for you time.
