A liquid manure spreader is described which comprises a frame having a plurality of frame portions and having articulation means between each frame portion for permitting relative movement of each frame portion in response to directional changes of the liquid manure spreader. Such an arrangement facilitates turning of the liquid manure spreader. The liquid manure spreader also comprises two or more liquid manure tanks which are in fluid communication with each other. A pump may be used to re-circulate the liquid manure between the tanks, transfer the liquid manure to a spreader means, or both. Liquid manure can also be transferred between the tanks to thereby achieve a pre-determined weight distribution between the tanks. Such a fluid arrangement permits better weight distribution leading to better handling of the manure spreader.

Having described the invention, what is claimed is: 1. A liquid manure spreader comprising: a) a frame having a front end and a rear end, the front end having hitch means for connection to a towing vehicle, the rear end having spreader means for spreading liquid manure; b) two or more spaced apart tanks, each tank mounted on to a respective frame portion of the frame, the tanks in fluid communication with one another through one or more fluid conduits; c) a set of axles mounted beneath each frame portion having wheels mounted thereto on opposite sides of the frame; and, d) the frame having articulation means located between each frame portion permitting relative movement of each frame portion in response to directional changes of the liquid manure spreader. 2. The liquid manure spreader of claim 1, wherein the articulation means has a vertical pivot axis passing therethrough and wherein the articulation means permits relative pivoting movement of each frame portion about the vertical pivot axis. 3. The liquid manure spreader of claim 2, wherein adjacent frame portions pivot in opposite directions about the vertical pivot axis in response to directional changes of the liquid manure spreader. 4. The liquid manure spreader of claim 2, wherein the articulation means limits translational movement of the vertical pivot axis relative to the frame. 5. The liquid manure spreader of claim 1, wherein the articulation means comprises a pintle hitch. 6. The liquid manure spreader of claim 1, wherein the liquid manure is selectively transferred from a certain tank to achieve a pre-determined weight distribution. 7. The liquid manure spreader of claim 6, wherein the liquid manure is selectively transferred to another of the tanks to achieve the pre-determined weight distribution. 8. The liquid manure spreader of claim 1, wherein the center of each tank is mounted to its respective frame portion forward of the center of the set of axles. 9. The liquid manure spreader of claim 1, wherein the spreader comprises front and rear tanks, front and rear frame portions, a first set of axles mounted beneath the front frame portion rearward of the center of the front tank by a first distance, a second set of axles mounted beneath the rear frame portion rearward of the center of the rear tank by a second distance, the first distance greater than the second distance. 10. The liquid manure spreader of claim 1, wherein each tank has a fluid capacity of between 3,000 and 8,000 gallons. 11. The liquid manure spreader of claim 1, wherein each tank is in fluid communication with an adjacent tank through two fluid conduits. 12. The liquid manure spreader of claim 11, wherein the liquid manure is re-circulated between the tanks through one of the fluid conduits. 13. The liquid manure spreader of claim 1, wherein the liquid manure spreader comprises one or more pumps in fluid communication with one or more fluid conduits. 14. The liquid manure spreader of claim 13, wherein the liquid manure is re-circulated between the tanks using the pump. 15. A system for spreading liquid manure comprising: a) a liquid manure spreader comprising: a frame having a front end and a rear end, the front end having hitch means for connection to a towing vehicle, the rear end having spreader means for spreading liquid manure; two or more spaced apart tanks mounted to the frame and in fluid communication with one another through one or more fluid conduits; at least two sets of axles mounted beneath the frame having wheels mounted thereto on opposite sides of the frame; one or more pumps in fluid communication with the one or more fluid conduits; and, b) selectively transferring liquid manure from a certain tank to achieve a pre-determined weight distribution between the tanks. 16. The system of claim 15, wherein the weight distribution is pre-determined based on the total weight of the spreader, the angle with respect to horizontal, the available traction of the towing vehicle, or a combination thereof. 17. The system of claim 15, wherein the liquid manure is transferred from one tank to another of the tanks automatically according to pre-determined criteria. 18. The system of claim 15, wherein the liquid manure is selectively transferred to another of the tanks to achieve the pre-determined weight distribution.
