I,v posted this before but is worth bring up again.From a bobcat feild rep thier fluid is simply a GL4 with wet brake additive[nothing special]. I told the factory rep that if I needed the special b-c only fluid,that the magnusson moss act required them to provide it free.I havent checked for sure but I think this fluid is what most hyd trans use.I see no reason to pay bobcat 4 times the price.:laughing:
