  • Patent number: 11079921
    Abstract: A method includes, with a processor executing computer-readable instructions stored within a memory device, displaying, on a display device and via at least one graphical user interface (GUI), a first interface element associated with a machine selection, receiving, via the first interface element, a first input comprising an indication of a machine, displaying, on the display device and via the at least one GUI, one or more second interface elements associated with tool parameters, receiving, via the second interface element, a second input comprising an indication of the tool parameters, determining, based at least in part on the machine and the tool parameters, one or more tools for use with the machine, and presenting, via the at least one GUI, a graphical representation of the one or more tools.

  • Patent number: 10184295
    Abstract: A machine comprising a frame including a front-right portion, a front-left portion, a rear-right portion, and a rear-left portion. The machine includes a first jack coupled with the front-right portion for raising or lowering the front-right portion, a second jack coupled with the front-left portion for raising or lowering the front-left portion, a third jack coupled with the rear-right portion for raising or lowering the rear-right portion, and a fourth jack coupled with the rear-left portion for raising or lowering the rear-left portion. The machine includes a front jack leveling system operatively coupled with the first jack and the second jack. The front jack leveling system controls the first jack and the second jack such that a first movement of the first jack in a first direction corresponds to a second movement of the second jack in a second direction that is opposite from the first direction.

  • Patent number: 8943702
    Abstract: A guard for a sensor apparatus in a tilting arrangement. The guard includes a first tubular portion supported on the tilting arrangement, a longitudinal portion extending from the first tubular portion, and a second tubular portion extending from the longitudinal portion. The first tubular portion provides a first cavity adapted to partially enclose a first mounting stud of the sensor apparatus. Similarly, the second tubular portion provides a second cavity adapted to partially enclose a second mounting stud of the sensor apparatus. And, the longitudinal portion provides a recess adapted to partially enclose a lever member of the sensor apparatus.

  • Patent number: 8387755
    Abstract: A lubrication system is provided that includes a pump operatively connected to one or more supply lines for delivery of a lubricant, the system including a first pressure sensor associated with the supply line at a first position, and a second pressure sensor associated with the supply line at a second position downstream of the first position and pump, a controller configured to receive pressure signals and control operation of the pump based upon the pressure differential between the pressures at the first position and second position. The pressure differential may be employed to determine when a pressure at a third position downstream of the second position has been achieved. At least one of the pressure sensors may be positioned adjacent to the pump, the controller further being operable to deactivate the pump in the event that a maximum pump pressure has been met.
