Abstract: A monitor display system for giving warning of the existence of an undesirable state of one or more of a plurality of monitored operating conditions of an engine-powered vehicle. The system comprises a self-contained logic circuit which energizes both master warning lamps and an audible buzzer providing a two-level warning by discerning the severity of the operating condition, and a display panel-fault indicator module including a fault indicating circuit as a part thereof electrically connected with each operating condition by a pair of sensing switches of different actuation settings, and with the module having a componetized design which provides infinite display panel shapes and formats for non-dedicated display of monitored conditions.

Abstract: A rear steer angle indicator unit for an agricultural or earth moving tractor having a steerable mainframe articulately connected to an independently wheel-mounted rear engine frame: the rear steer indicator unit comprising a sensing unit (33) capable of converting mechanical motion to electrical signals and mounted on a portion (22) of a mainframe (12) spaced away from the articulation joint (18) for the tractor (11); a gauge (37) mounted in the tractor cab (13) and electrically connected to the sensing unit (33) for receiving signals therefrom indicating the direction of movement of the engine frame (14) relative to the mainframe (12); a sensing arm unit (40) mounted independently of the sensing unit (33) in a bushing (42) provided therefore in a portion (22) of the mainframe (12); and a linkage unit (45) connected between the sensing arm unit (40) and a tongue member (27) of the engine frame (14) for translating movement of the engine frame (14) to rotation of the sensing arm (40) within the sensing unit (

Abstract: A saddle construction for use in a motor grader having a fore-and-aft extending main frame comprising an upper portion having a generally longitudinal extending section forming a forward facing and a rear facing. The facings have a generally vertical orientation. The main frame has first and second pins slidably mounted transversely in the main frame in longitudinal spaced apart relationship. The forward facing of the saddle upper portion straddles the main frame and is fixably mounted to opposite ends of the first pin. In like manner, the rear facing straddles the main frame and is fixably mounted to opposite ends of the second pin. The saddle further includes a lower portion straddling the main frame and fixably mounted the rear facing. The main frame has a plurality of recesses formed in respective side walls of the main frame in longitudinal spaced apart relationship for seatably receiving inwardly directed landings formed on the facings.

Abstract: A steering unit and control console for a vehicle comprising a pedestal assembly for supporting the vehicle steering unit and at least one vehicle control lever, a platform device secured to the vehicle and pivotally mounting the pedestal assembly in an upwardly position thereon for movement of the pedestal assembly about a transverse axis to adjust the position of the pedestal assembly, a locking unit pivotally mounted on the platform device for locking the pedestal assembly against the pivotal movement out of any one of a plurality of adjusted positions of the pedestal assembly, and a release unit for disengaging the locking unit whereby the pedestal assembly is pivotally movable to an adjusted position, the console including further the release unit having a handle which protrudes forwardly from the pedestal assembly and which is disposed below the steering unit, and further wherein the locking unit provides for a firm locked engagement of the locking mechanism to eliminate potential means of looseness.

Abstract: A method of arranging function controls for a vehicle, which method provides a control system that is easily converted from a two-hand control for left and right blade lift functions to a one-hand control for the same functions. The method comprises the steps of placing the blade lift levers at the extreme left and right ends of a pivot shaft inserted through the control console, with the third lever for the optional functional control placed adjacent to the right blade lift lever; and placing the left and right blade lift control valves at opposite ends of the control valve stack similarly to the placement of the left and right control levers, with the optional functional control valve placed adjacent to the right blade lift control valve as with the optional control lever.

Abstract: The function control levers of an earth moving vehicle such as a motor grader are mounted on a pedestal which may be selectively pivotally tilted for optimum position for the operator, sitting or standing. The pedestal comprises a trapezoidal-type configuration of an upwardly extended pair of parallel panels pivotally mounted at their base and pivotally connected across their upper ends by a steering wheel unit such that two horizontally spaced pairs of vertically spaced shafts define the articulating corners of the pedestal. A series of hydraulic valves are mounted forwardly of the pedestal. The function controls are pivotally mounted on one of the upper pedestal shafts for manipulation and includes linkage connecting the function controls to the valves which maintain the controls in a substantially constant position relative to the operator regardless of the pedestal tilt position.
