Disclosed is a vehicle. The vehicle comprises a first hydraulic pump, a first hydraulic motor, a first axle shaft, a second hydraulic pump, a second hydraulic motor, a second axle shaft, a first bypass, a first linkage, a second bypass and a second linkage. The first hydraulic motor is connected to the first hydraulic pump by a first hydraulic porting. The first axle shaft is driven by the first hydraulic motor. The second hydraulic motor is connected to the second hydraulic pump by a second hydraulic porting. The second axle shaft is driven by the second hydraulic motor. The first bypass is associated with the first hydraulic porting. The first linkage is connected to the first bypass. The second bypass is associated with the second hydraulic porting. The second linkage is connected to the second bypass. The first bypass and the second bypass are actuated substantially simultaneously by a single actuating mechanism.
A vehicle comprising:
A vehicle comprising:
A method of placing a pair of hydrostatic closed loop systems in a bypass mode, comprising actuation of a single handle connected to a linkage system that is connected to a pair of bypass actuators, thereby placing both hydrostatic closed loop systems in a bypass mode, wherein each hydrostatic closed loop system is located in a separate housing.
