Abstract
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.
