An electric drive assembly for operation with a component of a work vehicle having an SAE standard hydraulic pump/motor mount includes an electric machine having a shaft and a mounting flange. An adapter housing defines an interior space between a component mounting flange and an electric machine mounting flange. The electric machine mounting flange is sized and configured to mate with the mounting flange of the electric machine. The component mounting flange has a bolt hole pattern and a mounting pad each of a complementary size and configuration to that of the SAE standard hydraulic pump/motor mount. A gear set at least in part disposed in the interior space of the adapter housing is configured to effect a gear ratio change and transfer power between the shaft of the electric machine and a drive shaft.

Electric drive with hydraulic mounting interface

A hydraulic power module for a crop harvester, and in particular a cotton harvester, having an engine. The hydraulic power module includes a main drive gear, a drive shaft extending through the main drive gear, and a clutch operatively connected to the drive shaft, wherein the clutch has an engaged position and a disengaged position. The engaged position of the clutch fixedly connects the main drive gear to the drive shaft and the disengaged position of the clutch disconnects the main drive gear drive from the drive shaft. The hydraulic power module further includes a first pump device directly coupled to the drive shaft, wherein the first pump device is driven by the drive shaft during rotation of the drive shaft. A second pump device is indirectly connected to the drive shaft through the clutch, and is driven by the drive shaft when the clutch is in the engaged position.
