Abstract: A method for displaying a position of a boom-mounted implement relative to a swing indicator for an excavator having boom swing capabilities comprises displaying a propulsor icon of a set of propulsion units of the excavator on a display screen, displaying a housing icon of a housing of the excavator relative to the propulsor icon on the display screen, displaying a boom icon of the boom-mounted implement relative to the housing icon on the display screen, displaying the swing indicator relative to the propulsor icon on the display screen, updating a rotational position of the housing icon relative to the propulsor icon based on real-world movement of the housing relative to the set of propulsion units, and updating a location of the swing indicator relative to the propulsor icon based on real-world movement of the boom-mounted implement relative to the housing from the boom swing capabilities.

Abstract: A follower pinion apparatus can include a swing gear system comprised of a swing gear and a swing motor pinion. The follower pinion apparatus can also include a nonmetallic follower pinion positioned to mesh with the swing gear and a sensor configured to sense a position of the follower pinion.

Abstract: A control system is disclosed for a machine having a work tool and a traction device. The control system may have an actuator configured to adjust a depth of the work tool relative to a ground surface, a tool sensor configured to generate a first signal indicative of a performance parameter of the work tool, a speed sensor configured to generate a second signal indicative of an actual speed of the traction device, and a controller in communication with the actuator, the tool sensor, and the speed sensor. The controller may be configured to determine that the work tool is engaged with the ground surface and, when the work tool is determined to be engaged with the ground surface, to make a comparison of the actual speed of the traction device with a rotational speed threshold. The controller may then be configured to selectively cause the actuator to adjust the depth of the work tool based on the comparison.

Abstract: A control system for controlling a position of an implement of a machine operating on a terrain includes a controller configured to generate a signal indicative of a desired cylinder velocity of an actuator associated with the implement of the machine and an operating mode sensor configured to generate a signal indicative of an operating mode of the machine. The control system includes an instability detection module which receives the signal indicative of the desired cylinder velocity of the actuator from the controller and the signal indicative of the operating mode of the machine from the operating mode sensor. The instability detection module detects an instability condition based on the signal indicative of the desired cylinder velocity of the actuator and selectively adjusts a controller gain associated with the desired cylinder velocity based at least in part on the instability condition and the operating mode of the machine.

Abstract: A drive system for a mobile machine is disclosed. The drive system includes a power source configured to generate mechanical power, and a transmission driven by the power source, a traction device driven by the transmission. The drive system further includes a first input device configured to generate a signal to operate the machine, a second input device configured to receive an operator selection of one of a plurality of transmission modes, and a controller in communication with the first input device and the transmission. The controller is configured to adjust operation of the transmission to control a speed rate of change of the traction device in response to the signal from the first input device and based on the operator-selected one of the plurality of transmission modes.
