Abstract

A tractor includes a cab mounted analysis/display unit (1) connected to a number of on-board sensors for detecting speed, fuel flow, etc and also capable of receiving data input manually or via a data carrier. The unit (1) is also connected to an on-board GPS navigation system (24), and includes means for generating maps of tractor-related parameters and/or parameters derived therefrom. The math usefulness of the system is in derby “on the go” maps of cost related data for a given field operation. Cost maps for cumulative operations and maps of gross profit margin are possible by adding “on the go” generated cost data to previously generated cost and/or yield data as the tractor performs an operation in a field.

Claims

1. An apparatus for mapping the performance of an agricultural tractor during operation in an agricultural field comprising:

a sensor that generates a signal that is representative of an operating characteristic of the agricultural tractor; and

a controller that is responsive to said signal from said sensor and that generates a performance map of the performance of the agricultural tractor as a function of an area in the agricultural field in which the agricultural tractor is operated.

2. The apparatus defined in claim 1 wherein said sensor is an engine sensor that generates a signal that is representative of an operating characteristic of an engine provided on the agricultural tractor.

3. The apparatus defined in claim 2 wherein said engine sensor is a sensor that generates a signal that is representative of the speed of the engine.

4. The apparatus defined in claim 2 wherein said engine sensor is a sensor that generates a signal that is representative of the amount of fuel supplied to the engine.

5. The apparatus defined in claim 1 wherein said sensor is a speed sensor that generates a signal that is representative of the speed of the tractor.

6. The apparatus defined in claim 1 wherein said sensor is a power take off sensor that generates a signal that is representative of an operating characteristic of a power take off provided on the agricultural tractor.

7. The apparatus defined in claim 6 wherein said power take off sensor is a sensor that generates a signal that is representative of the speed of the power take off.

8. The apparatus defined in claim 1 wherein said sensor is a linkage sensor that generates a signal that is representative of an operating characteristic of a three point linkage provided on the agricultural tractor.

9. The apparatus defined in claim 8 wherein said linkage sensor is a sensor that generates a signal that is representative of the draft force of the three point linkage.

10. The apparatus defined in claim 8 wherein said linkage sensor is a sensor that generates a signal that is representative of the position of the three point linkage.

11. The apparatus defined in claim 1 wherein said sensor is a position sensor that generates a signal that is representative of the position of the tractor in the agricultural field.

12. The apparatus defined in claim 11 wherein said position sensor is a global satellite navigation system.

13. The apparatus defined in claim 1 further including an actual speed sensor that generates a signal that is representative of the actual speed of the agricultural tractor over ground, said controller being responsive to said signals from said sensor and said actual speed sensor and generating the performance map.

14. The apparatus defined in claim 1 further including a theoretical speed sensor that generates a signal that is representative of the theoretical speed of the agricultural tractor over ground if no wheel slip is occurring, said controller being responsive to said signals from said sensor and said theoretical speed sensor and generating the performance map.

15. The apparatus defined in claim 1 further including a manual input device that generates a signal that is representative of a parameter, said controller being responsive to said signals from said sensor and said manual input device for generating the performance map.
