Abstract
A hydrostatic driveline has a power source, a transmission portion, a hydrostatic pump, a hydrostatic motor, a transfer case, a first axle assembly, an inter-axle drive shaft, and a second axle assembly. The transmission portion is drivingly engaged with the power source. The hydrostatic pump is in driving engagement with the transmission portion. The hydrostatic motor is in fluid communication with the hydrostatic pump. The transfer case is in driving engagement with the hydrostatic motor. The inter-axle drive shaft is in driving engagement with the transfer case and the transmission portion. The transmission portion, the hydrostatic pump, the hydrostatic motor, the transfer case, and the inter-axle shaft form a first power path for the hydrostatic driveline and the transmission portion and the inter-axle shaft form a second power path for the hydrostatic driveline.
