Abstract: A system for controlling an operation of a machine is disclosed. The system includes an image capturing device and a controller. The image capturing device generates a signal indicative of a surrounding area of the machine. The controller is in communication with the image capturing device. The controller determines a preceding work cycle of the machine comprising a dig segment and determines a preceding segment associated with the preceding work cycle to be a dump segment. The controller further identifies a work aggregate within the surrounding area of the machine, when the preceding segment of the preceding work cycle is the dump segment. Further, the controller determines a distance between an implement of the machine and the work aggregate and issues a shift request to downshift a gear drive of a transmission system of the machine, if the distance is less than a predefined distance.

Abstract: A hydraulic system for a machine is provided including a first cylinder, a pump and an operator input device for entering a commanded rate of flow of hydraulic fluid to the first cylinder. A control valve operatively is connected between the pump and the first cylinder. A sensor is configured and arranged to provide signals relating to a first operating characteristic of the machine. A controller is in communication with the operator input device, the control valve and the sensor. The controller is configured to determine a skill level of an operator of the machine based on a comparison of the first operating characteristic of the machine and a first threshold and to direct the control valve to provide hydraulic fluid to the first cylinder at an adjusted hydraulic fluid flow rate if the skill level of the operator is below a predetermined level.
