Abstract

An agricultural system including a tractor and an implement powered by the tractor. The implement having a plurality of hydraulic fluid using devices, at least one transducer, and a communications device. The transducer is configured to generate a signal representative of a hydraulic load requirement of the plurality of hydraulic fluid using devices. The communications device conveying the signal to the tractor. The tractor is configured to alter a hydraulic fluid characteristic supplied to the implement dependent upon the signal.

Claims (32)

1. An agricultural system, comprising:

a tractor; and

an implement powered by said tractor, said implement including:

a plurality of hydraulic fluid using devices;

at least one transducer configured to obtain hydraulic load requirements of said plurality of hydraulic fluid using devices;

a resolving means resolving a highest hydraulic load requirement from said load requirements;

a generating means to generate a signal representative of said highest hydraulic load requirement of said plurality of hydraulic fluid using devices; and

a communications means for conveying said signal to said tractor, said tractor being configured to alter a hydraulic fluid characteristic supplied to said implement dependent upon said signal.

2. The agricultural system of claim 1 , further comprising a plurality of valves interconnecting at least two of said plurality of hydraulic fluid using devices, said at least one transducer being fluidly coupled between said plurality of valves, said plurality of valves being configured to convey a hydraulic pressure therethrough such that said at least one transducer is exposed to a higher of a fluid pressure from said at least two of said plurality of hydraulic fluid using devices.

3. The agricultural system of claim 1 , wherein at least one of said plurality of hydraulic fluid using devices is a fan motor.

4. The agricultural system of claim 1 , wherein at least one of said plurality of hydraulic fluid using devices is a seed drive motor.

5. The agricultural system of claim 1 , wherein said implement is an agricultural planter.

6. The agricultural system of claim 1 , wherein said at least one transducer is a plurality of transducers each associated with at least one of said plurality of hydraulic fluid using devices.

7. The agricultural system of claim 6 , wherein said plurality of transducers are arranged such that said signal represents a highest of the hydraulic load requirement of said plurality of hydraulic fluid using devices.

8. The agricultural system of claim 1 , wherein said signal is used by said tractor to alter a pressure of the hydraulic fluid supplied to said implement.

9. The agricultural system of claim 8 , wherein said plurality of hydraulic fluid using devices includes a fan motor and a seed drive motor.

10. The agricultural system of claim 9 , wherein said signal represents a higher of a hydraulic load requirement of said fan motor and a hydraulic load requirement of said seed drive motor.

11. An agricultural implement powered by a tractor, the implement comprising:

a plurality of hydraulic fluid using devices;

at least one transducer configured to obtain hydraulic load requirements of said plurality of hydraulic fluid using devices;

a resolving means resolving a highest hydraulic load requirement from said load requirements;

a generating means to generate a signal representative of said highest hydraulic load requirement of said plurality of hydraulic fluid using devices; and

a communications means for conveying said signal to the tractor, the tractor being configured to alter a hydraulic fluid characteristic supplied to the implement dependent upon said signal.

12. The agricultural implement of claim 11 , further comprising a plurality of valves interconnecting at least two of said plurality of hydraulic fluid using devices, said at least one transducer being fluidly coupled between said plurality of valves, said plurality of valves being configured to convey a hydraulic pressure therethrough such that said at least one transducer is exposed to a higher of a fluid pressure from said at least two of said plurality of hydraulic fluid using devices.

13. The agricultural implement of claim 11 , wherein at least one of said plurality of hydraulic fluid using devices is a fan motor.

14. The agricultural implement of claim 11 , wherein at least one of said plurality of hydraulic fluid using devices is a seed drive motor.

15. The agricultural implement of claim 11 , wherein said implement is an agricultural planter.

16. The agricultural implement of claim 11 , wherein said at least one transducer is a plurality of transducers each associated with at least one of said plurality of hydraulic fluid using devices.

17. The agricultural implement of claim 16 , wherein said plurality of transducers are arranged such that said signal represents a highest of the hydraulic load requirement of said plurality of hydraulic fluid using devices.

18. The agricultural implement of claim 11 , wherein said signal is used by the tractor to alter a pressure of the hydraulic fluid supplied to said implement, thereby supplying said implement with hydraulic fluid at a pressure representative of said highest hydraulic load requirement.

19. The agricultural implement of claim 18 , wherein said plurality of hydraulic fluid using devices includes a fan motor and a seed drive motor.

20. The agricultural implement of claim 19 , wherein said signal represents a higher of a hydraulic load requirement of said fan motor and a hydraulic load requirement of said seed drive motor.
