  • Large rectangular baler having hydraulically powered functions, and control system therefor
    Patent number: 6651416
    Abstract: A large rectangular baler includes pick-up and packer rotors, a pivotable stuffer, a plunger head, a knotter shaft and a needle yoke, and tension panels that are all driven hydraulically and independently controlled through electrically controlled valves that actuate the various hydraulic power devices used to power the various functions. An electronic control unit is coupled to each of the control valves and receives feedback signals from the controlled functions which are compared with values representing desired function results so as to further control the valves to attain the desired results. In addition to the feedback signals from the powered functions, signals from a bale length sensor and a ground speed sensor are also coupled to the electronic control unit for use in controlling the powered functions.
