Abstract

A control system for an agricultural implement such as a large round baler includes a microprocessor-based implement module mounted to the baler and a microprocessor-based input device mounted within the cab of the tractor behind which the baler is towed. A communications link extends between the input device and the implement control device, for communicating signals therebetween. Sensors are interconnected with one or more of the components of the large round baler for sensing operation of such components, and providing signals to the implement control device microprocessor indicative of one or more baler operations. The sensor signals are analyzed by the microprocessor, and signals are communicated via the communications link to the cab module microprocessor. The input device includes a visual display, and the display is actuated responsive to the cab module microprocessor to provide a visual indication to the operator of the one or more sensed operations of the baler. The baler operations are controlled responsive to input commands provided by the operator to the cab module, which are communicated over the communication link to the implement module microprocessor.

Claims

1. A baler adapted to be towed by a towing vehicle comprising:

a bale-forming arrangement for forming a bale of crop material;

a bale wrapping mechanism for dispensing wrap material onto a bale; and

a control system for controlling operation of the bale wrapping mechanism in response to operator commands, the control system including an input device mounted in the towing vehicle for receiving input commands from the operator, the input device including processing means;

an implement control device mounted to the baler and interconnected with the bale wrapping mechanism for controlling operation of the bale wrapping mechanism, the implement control device including processing means; and

communication means between the input device and the implement control device for adjusting the control of the bale wrapping mechanism provided by the implement control device in response to manual input commands provided by the operator to the input device.

2. The round baler of claim 1, wherein the communication means comprises a communication link extending between and interconnected with the input device and the implement control device.

3. The round baler of claim 2, wherein the input device comprises a cab module including an operator-actuated keypad and a visual display, and wherein the processing means comprises a microprocessor housed within the cab module.

4. A baler adapted to be towed by a towing vehicle comprising:

a bale-forming arrangement for forming a bale of crop material;

a bale size monitor for determining the size of the bale formed by the bale-forming arrangement; and

a control system for controlling the bale-forming arrangement in response to operator commands to control the size of the bale, the control system including an input device mounted in the towing vehicle for receiving bale size input commands from the operator, the input device including processing means;

an implement control device mounted to the baler and interconnected with the baler for controlling operation of the baler so as to control the size of the bale, the implement control device including processing means; and

communication means between the input device and the implement control device for adjusting the control of the bale-forming arrangement provided by the implement control device in response to manual bale size input commands provided by the operator to the input device.

5. A method of forming round bales of crop material, comprising the steps of:

providing a baler having a bale-forming arrangement for forming a cylindrical bale of crop material and having a bale wrapping mechanism;

securing the baler to a towing vehicle;

mounting a processor-based implement control device to the baler;

mounting a processor-based input device in the towing vehicle for receiving input commands from the operator;

interconnecting the implement control device with the bale wrapping mechanism; and

establishing communication between the input device and the implement control device for communicating input signals from the input device to the implement control device to control operation of the bale wrapping mechanism, and for communicating signals indicative of operation of the bale wrapping mechanism from the implement control device to the input device.

6. The method of claim 5, wherein the step of establishing communication between the input device and the implement control device comprises interconnecting a communication link between the input device and the implement control device.

7. A method of forming bales of crop material, comprising the steps of:

providing a baler having a bale-forming arrangement for forming a bale of crop material and having a bale size monitor;

securing the baler to a towing vehicle;

mounting a processor-based implement control device to the baler;

mounting a processor-based input device in the towing vehicle for receiving input commands from the operator;

interconnecting the implement control device with the baler so as to control the size of the bale formed by the bale-forming arrangement; and

establishing communication between the input device and the implement control device for communicating input signals from the input device to the implement control device to control the size of the bale, and for communicating signals indicative of bale size from the implement control device to the input device.
