Abstract

A variable payload towing vehicle with several storage containers for carrying bulk crop inputs. The storage containers are releasably attached to the vehicle and can be changed based on the type of crop inputs applied and any implements towed by the vehicle. The vehicle is also equipped with high flotation tires or tracks to minimize soil compaction. A delivery system in combination with a control system coordinates the movement of the crop inputs from the vehicle to places located off the vehicle. The vehicle may be equipped with articulated steering and all wheel steering to increase maneuverability.

Claims

1. An agricultural system for application of crop inputs to a field, the system comprising:

a variable payload towing vehicle comprising a plurality of primary crop input storage containers and low impact ground engaging mean;

a crop input applicator implement coupled to the towing vehicle, the implement comprising a plurality of secondary crop input storage containers, wherein a capacity of the primary storage containers on the towing vehicle is greater than a capacity of the secondary containers on the implement;

a control system associated with the towing vehicle and applicator implement that controls a flow of crop inputs from the primary storage containers on the towing vehicle to the secondary storage containers on the implement, controls a rate of release of crop inputs from the crop input applicator implement, and coordinates an application of multiple crop inputs so that the crop inputs are applied at a prescriptive rate; and

a delivery system configured to move crop inputs from the primary storage containers on the vehicle to the secondary storage containers on the applicator implement.

2. The system of claim 1 wherein the crop input implement is a planter.

3. The system of claim 1 wherein at least one primary crop input storage container on the towing vehicle carries liquid crop inputs.

4. The system of claim 1 wherein at least one primary crop input storage container on the towing vehicle carries dry crop inputs.

5. The system of claim 1 wherein the low impact ground engaging means on the towing vehicle is a plurality of high flotation tires.

6. The system of claim 1 wherein the delivery system is air assisted.

7. The system of claim 1 wherein the control system compensates for time it takes to move the crop inputs from the primary storage containers on the towing vehicle to the secondary storage containers on the implement.

8. The system of claim 1 wherein the control system is configured to control the application of multiple crop inputs from the implement as a function of the position of the vehicle in a field and site specific data which defines a prescription designed multiple crop inputs for various positions in the field.

9. The system of claim 1 wherein the control system includes a plurality of sensors and actuators on the implement to communicate a crop input level on the implement to the towing vehicle.

10. The system of claim 1 wherein the capacity of the primary crop input storage containers on the vehicle is at least twice the capacity of the secondary crop input store containers on the implement.

11. The system of claim 1 wherein the capacity of the primary crop input storage containers on the vehicle is about five times the capacity of the secondary crop input storage containers on the implement.

12. The system of claim 1 wherein the capacity of the primary crop input storage containers on the vehicle is greater than about 25,000 pounds.

13. A variable payload towing vehicle, the vehicle comprising:

a plurality of storage containers for holding bulk crop inputs on a chassis;

low impact ground engaging means;

a delivery system for moving the crop inputs from the storage containers to a towed implement;

a control system configured to control an application of multiple bulk crop inputs from the towed implement as a function of the position of the vehicle in a field and site specific data so that a prescription of desired crop inputs is applied at a desired positioned in the field; and

a hitch on the chassis for towing an implement.
