Abstract: A method for retrofitting a high drive track-type tractor with a rear entry electric drive motor module. The method includes inserting the rear entry electric drive motor module into a frame housing. The rear entry electric drive motor module includes an electric drive planetary gear assembly, and an electric motor. The method further includes attaching a reaction member to the rear entry electric drive motor module.

Abstract: An electric drive retrofit kit includes a rear entry electric drive motor module that includes an electric drive planetary gear assembly and a second electric drive planetary gear assembly which can be inserted into a rear final drive cavity of a frame housing for a tracked tractor with a high track drive. The electric drive retrofit kit may further include a generator, a cooling package, an additional water pump, a steering pump, a steering motor, power inverters with control modules, and electric cables.

Abstract: An electric drive system including an electric drive motor module. The electric drive motor module includes an electric drive planetary gear assembly, and an electric motor having a rotor shaft. The electric drive system further includes a first output member, a second output member, and a reaction member operatively associated with the rotor shaft.

Abstract: A hydraulic system is disclosed for use with a machine. The hydraulic system may have a tank, a motor with a fluid inlet and a fluid outlet, and a pump configured to draw fluid from the tank and discharge the fluid at elevated pressures to the motor. An output of the pump is adjustable to regulate a speed of the motor. The hydraulic system may also have a low-speed valve located between the fluid outlet of the motor and the tank. The low-speed valve may be configured to reduce a positive speed of the motor below a lowest positive speed attainable through control of pump output.
