Abstract: A braking system for a machine includes a first valve assembly having a first electronically actuated proportional valve, and a second valve assembly having a second electronically actuated proportional valve. The braking system includes a first pressure sensor and a second pressure sensor disposed downstream of the first and second valve assemblies, respectively. The first and second pressure sensors are configured to determine a first pressure and a second pressure of a braking fluid from the first and second valve assembly. The braking system also includes a controller configured to receive a signal indicative of the first pressure and the second pressure of the braking fluid and compare the first pressure and the second pressure. The controller is configured to selectively actuate at least one of the first electronically actuated proportional valve and the second electronically actuated proportional valve to substantially equalize the first pressure and the second pressure.

Abstract: A method of operating a machine with at least one hydraulically actuated friction clutch. The method includes selecting, via a mode selector, a starting point defining an initial setting. An endpoint defining a peak setting is selected via the mode selector. A control curve is employed based on at least the selecting of the starting point and the selecting of the endpoint. An inching pedal of the machine is positioned to between 0 percent depressed and 100 percent depressed. At least one control command is generated as a function of the employing of the control curve and the positioning of the inching pedal. At least one control valve of at least one hydraulically actuated friction clutch is operated according to the at least one control command.

Abstract: A hydraulic valve assembly including a main control valve having a valve body housing a valve member that is movable between a first valve position and a second valve position. The hydraulic valve assembly further includes a mechanical interface operatively coupled to the movable valve member to manually move the movable valve member between the first valve position and the second valve position and one or more electro-hydraulic actuators operatively coupled to the movable valve member to automatically move the movable valve member between the first valve position and the second valve position in response to receiving a control signal from a controller.

Abstract: A hydraulic cylinder assembly having a first portion connected to a first bar. A rod is constrained within a cylindrical recess by a first end and a second end of housing. A maximum travel of a first end of the rod within the housing defines a stroke of the hydraulic cylinder assembly. At least two structures are coupled with each other along a first edge and a second edge to form a space therewithin. A second surface of the structures having a first profile being at a first predetermined distance, and a second profile being at a second predetermined distance, from an axis of each of the at least two structures. The second predetermined distance is greater than the first predetermined distance. The structures are mounted over rod proximate to second end of rod to form a collar for limiting the stroke of the hydraulic cylinder assembly of a machine.

Abstract: System and method for inhibiting damage to a moldboard of a mobile work machine including a blade pitch sensor, a camera configured to detect the blade cutting edge, and a controller configured to determine a maximum allowable pitch of the blade based upon current width of the cutting edge determined from a camera signal. The controller determines if the current measured pitch is greater than the maximum allowable pitch of the blade based upon characteristics of the mobile work machine and the current width of the cutting edge to prevent damage to the moldboard.
