i believe this loader to be a GB however I’ve yet to find any identifying SN or mark to prove it. It is JD green with ford blue paint underneath. It has mounting brackets that had been on a 1972 4320 JD so should bolt up to any 10-20 series JD small frame row crop or wheatland tractor. 78” bucket and no visible cracks or breaks. Hi lift. Comes with triple spool valve and hoses to connect to tractor SCV. Spool valve mounts in cab or on floor deck above rear axle on right side. Cylinders are good and loader is straight. $1800.00 OBO. Delivery available.
