| Abstract: | Tractor hydraulic fluids are tested to maximize their performance levels and to ensure manufacturer's standards are met. Common tractor hydraulic fluid tests include: Gear Wear Protection, Brake Chatter Reduction, Wet - Clutch Capacity, and Pump Performance tests. These tests are run by Southwest Research Institute, in the U. S. A. , for tractors built by John Deere and Case - New Holland. This paper details current methods for evaluating tractor hydraulic fluids. The tests that are described utilize full size equipment and were developed by the tractor' s original equipment manufacturers (OEMs). |
