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.
