Abstract
A machine configured to prevent unintentional motion in a linkage pivotally connected to a frame may include a first hydraulic actuator connected to the linkage and a second hydraulic actuator connected to the linkage. The machine may include a sensor and an electronic control module in communication with the sensor. The electronic control module may be configured to close a valve of the first hydraulic cylinder and/or cancel an actuation command to one of the first hydraulic actuator and the second hydraulic actuator in response to the electronic control module determining unintentional motion of the linkage has occurred based on the sensor.
