This paper describes some of the design criteria, major components, unique features, hydraulic circuitry, and durability testing used to develop a new power shift transmission for the JD844 Front End Loader.The planetary pack with four forward and three reverse speeds, drop train gears, output shaft with a parking collar and hydraulic valving were designed to fulfill the JD844 requirements.High torque and energy capacity along with a new pressure modulating valve provides smooth and rapid shuttle shifting from this transmission at full power, which is vital to the productivity of the JD844 Loader.Extensive laboratory, dynamometer, and field testing has proven the performance and reliability of the JD844 Loader transmission.
