1973 Case 580 CK weight / Center of Gravity

Hi Andy that information i quote directly from the National Farm &power Equipment Dealers Association "Industrial Equipment Guide" that every dealers in north America use and still use today because this books also gives you the factory price of all those equipment coming out of the factory and also gives you the price to pay for used equipmednt as is or depending on the year. in other word I do not think of anything else more reliable.We always used it when we did trade. A 580CK with the loader is weighing 6262lbs. and a 580CK with the loader and the backhoe with a 24" bucket is weighing 10,289 lbs for diesel   and 10,089lbs for gaz . They don't list the weigh of the bucket alone but you can fairly guess it at 400 lbs. Hope this to be helpful. Jcmarleau.
