  • Patent number: 9840273
    Abstract: A steering system for a machine is disclosed. The steering system may include a first pilot system including a first pilot source and a first set of electrohydraulic valves, and a second pilot system including a second pilot source and a second set of electrohydraulic valves. The first pilot system and the second pilot system may be configured to move the steering valve via pilot flow of the hydraulic fluid. The steering system may further include an electrohydraulic selector valve configured to regulate pilot flow to the first set of electrohydraulic valves and the second set of electrohydraulic valves. The electrohydraulic selector valve may be a two-position, five-way valve.
    Type: Grant

  • Patent number: 9016513
    Abstract: A splashguard is disclosed for use with a tank. The splashguard may include a main channel formed by an elongated base plate and side walls extending generally orthogonally from the elongated base plate by a first distance. The splashguard may also include a first end channel formed by a base plate and side walls extending generally orthogonally from the base plate by a second distance greater than the first distance. The first end channel may also be formed by an end wall extending generally orthogonally from the base plate by the second distance. The splashguard may further include a second end channel substantially identical to the first end channel. A first flow path may be maintained between the elongated base plate of the main channel and the base plate of the first end channel. A second flow path may be maintained between the elongated base plate of the main channel and the base plate of the second end channel.
