A backhoe loader comprises a front chassis, a rear chassis, a rotatable operator workstation, and a chassis lock mechanism. The front chassis comprises the loading assembly and the rear chassis is connected to the front chassis along a vertical axis joint by a pin lock assembly. The rotatable operator workstation is positioned in the rear chassis, which is positioned inside a bearing mounted cabin which is slewable in clockwise and counterclockwise directions. The operator workstation enables manoeuvring of the front chassis with respect to the rear chassis using the pin lock assembly. The chassis lock mechanism is achieved using two single acting hydraulic cylinders that are mounted horizontally on rear chassis. These hydraulic cylinders are actuated during the excavation operation which in turns locks the oscillation of vehicle and front and rear chassis acts rigidly like a single body. This rigidity of the vehicle provides the required stability during excavation.
