Here are the 3 Pins used on the Eagle Hitch linkage on the SC DC 400 700 800 730 & 830 tractors. We’ve searched for a long time to find the correct pins at an economical price, and here they are. Made in the USA. The last I checked, Case wanted 3 times this price. This set will be shipped as shown with the hair pin, as this is correct for the SC DC 400 700 800. The 730 & 830 use a cotter pin. Case most likely made this change to save a few pennies. Case part number O9213AB, later changed to A27657. You are buying the set of 3 as shown. If you need less than 3, contact us.
