The invention claimed is: 1. An agricultural windrower, comprising: a vehicle chassis; a lift frame movably mounted to said vehicle chassis; and a crop harvesting header coupled with said lift frame, said header including a main frame and an integrated header float system, said header float system having at least one float cylinder coupled with said main frame and a position sensor on said header indicating the relative position of said float cylinder. 2. The agricultural windrower of claim 1, wherein said header includes a suspension movably supporting said main frame from said lift frame, each at least one said float cylinder coupled between said suspension and said main frame. 3. The agricultural windrower of claim 2, wherein said suspension includes a plurality of links movably supporting said main frame, each said float cylinder being coupled between said main frame and a corresponding one of said plurality of links. 4. The agricultural windrower of claim 1, wherein said at least one float cylinder comprises two float cylinders. 5. The agricultural windrower of claim 1, wherein said header includes a hydraulic float circuit fluidly coupled with each at least one said float cylinder. 6. The agricultural windrower of claim 5, further including a controller receiving signals from said position sensor and which controllably actuates said hydraulic float circuit. 7. The agricultural windrower of claim 6, including at least one lift cylinder coupled between said vehicle chassis and said lift frame, said controller being configured with a terrain following mode for controllable actuation of each said lift cylinder to raise and lower said header dependent upon a relative vertical position between said main frame and said lift frame. 8. The agricultural windrower of claim 6, wherein said windrower includes an operators cab, and said controller is located on one of said operators cab and said header. 9. The agricultural windrower of claim 1, wherein said lift frame directly interconnects said header with said vehicle chassis. 10. The agricultural windrower of claim 9, wherein said lift frame is pivotally coupled with said vehicle chassis. 11. A crop harvesting header for use with an agricultural harvester, comprising: a main frame; a suspension movably coupled with said main frame, said suspension configured to selectively mount to one of a plurality of differently configured types of agricultural harvesters; and a header float system integrated into said header, said header float system having at least one float cylinder coupled between said main frame and said suspension and a position sensor on said header indicating the relative position of said float cylinder. 12. The crop harvesting header of claim 11, wherein said suspension includes a plurality of links movably supporting said main frame said plurality for links being configured to selectively couple with one of said plurality of differently configured agricultural harvesters. 13. The crop harvesting header of claim 12, wherein each said float cylinder is coupled between said main frame and a corresponding one of said plurality of links. 14. The crop harvesting header of claim 11, wherein said suspension is configured to selectively mount to one of a windrower and a combine. 15. The crop harvesting header of claim 11, wherein said suspension is configured to selectively mount to one of a lift frame on a windrower and a feederhouse on combine. 16. The crop harvesting header of claim 11, wherein said at least one float cylinder comprises two float cylinders. 17. The crop harvesting header of claim 11, wherein said header includes a hydraulic float circuit fluidly coupled with each said float cylinder.
