Abstract
A dual drive driveline for a vehicle has a power source, a hydrostatic pump drivingly engaged with the power source, a first axle, a second axle, and a first hydrostatic unit in fluid communication with the hydrostatic pump. The first hydrostatic unit is drivingly engaged or selectively drivingly engaged with the first axle, and the first hydrostatic unit is not drivingly engageable with the second axle. A second hydrostatic unit in fluid communication with the hydrostatic pump, the second hydrostatic unit being drivingly engaged or selectively drivingly engaged with the second axle, and the second hydrostatic unit not being drivingly engageable with the first axle. A control unit is adapted to control a hydraulic displacement of at least one of the hydrostatic pump, the first hydrostatic unit and the second hydrostatic unit.
