Abstract:

An apparatus and method for controlling a work tool on a work machine are provided. The work machine may have first and second actuators, each actuator being operable in a vibratory mode and a non-vibratory mode, and each actuator being coupled to the work tool for changing the position of the work tool. The method may include simultaneously (i) operating the first actuator in a vibratory mode, (ii) operating the second actuator in a vibratory mode, and (iii) receiving a command to change the position of the work tool. The method may further include operating the first actuator in a non-vibratory mode to change the position of the work tool while operating the second actuator in a vibratory mode to vibrate the work tool, in response to receiving the command.
