Abstract: A machine having a powertrain including an engine operably connected to a torque converter and a transmission. The machine includes a control system receive an activation signal indicative of an automatic mode operation of the machine and command the torque converter to remain in a direct-drive mode while the transmission shifts from a first gear ratio to a second gear ratio. The control system also limits engine speed below a first engine speed limit when a gear ratio setting of the transmission is indicative of the second gear ratio.

Abstract: A machine includes an engine, an electronic display device, and a controller configured to: receive one or more signals indicating an identification of a machine operator; retrieve a name of the operator associated with the identification of the operator in a first data set of machine operators; retrieve one or more saved machine parameters associated with the name of the operator in a second data set of machine parameters; and set one or more current machine parameters to the one or more saved machine parameters.

Abstract: A system and method to access a machine through a mobile device includes sending a machine key to a controller on-board the machine, and a mobile device key to the mobile device using a remote server. The mobile device sends a mobile device ID to the controller. The controller determines the mobile device key based on the mobile device ID and the machine key. The controller sends a random number to the mobile device. The mobile device processes the random number to derive a first processed random number, and sends the first processed random number to the controller. The controller processes the random number to derive a second processed random number. The controller enables a start button to send a request to start the machine, when the first processed random number matches the second processed random number. The controller starts the machine upon receiving the request to start the machine.
