Abstract
A work vehicle includes a front axle, a rear axle, a chassis, a cab pivotally coupled to the chassis, a boom movably mounted on the chassis, and a boom cylinder for raising and lowering the boom. A rear suspension member raises and lowers the cab with respect to the rear axle. A front suspension member raises and lowers the chassis and the cab with respect to the front axle. An operator controlled command unit generates boom raise and lower signals. An electronic control unit (ECU) is connected to the front suspension member, the rear suspension member and the command unit. If vehicle speed is below a threshold speed, the ECU automatically operates the front and/or the rear suspension members to raise and lower the cab to improve visibility of the loader from the cab in response to the command unit operating the boom.
