A tag axle assembly for an agricultural machine, such as a harvester, and method for redistributing weight of the harvester from the rear axle of the harvester when a header is removed, or when replaced by a lighter header, at the front of the harvester. The tag axle assembly includes a tag axle with tires that may be lowered so that the tires contact the ground when no header is attached to the machine to absorb loads transferred from the front of the harvester to the rear axle and rear tires at the rear of the harvester. The tag axle and tires may be raised up from the ground, or the tag axle assembly may be removed from the harvester, when a header is attached to the front of the harvester causing redistribution of load from off the rear axle and rear tires.

1. A harvester comprising: a feeder connected at approximately a front end of the harvester, wherein the feeder comprises a connection point for a header to attach;at least one pair of front wheels, wherein each front wheel of the at least one pair are connected to opposing ends of a front axle for supporting loads about the front end of the harvester with the front wheels in contact with a ground surface; the front axle to serve as an axis that balances a moment of force that is exerted by the header; a replacement of the header with a light header reduces the moment of force around the axis,at least one pair of rear wheels, wherein each rear wheel of the at least one pair are connected to opposing ends of a rear axle for supporting loads about a rear end of the harvester with the rear wheels in contact with the ground surface;a tag axle assembly comprising: one or more rigid members connected approximately near to the rear end of the harvester;a tag axle connected to the one or more rigid members; andone or more tag tires connected about the tag axle to rotate in connection with the tag axle, wherein the one or more tag tires contact the ground surface to support loads about the rear end of the harvester upon replacement of the header with the light header; andan actuator that offloads a particular weight from the rear axle, that is adjustable based on a position of the tag axle as set by an operator. 2. The harvester of claim 1, wherein the tag axle assembly further comprises: a pivot rod connected to the one or more rigid members wherein the pivot rod is free to rotate within the connection to the one or more rigid members;one or more pivot members connected to the pivot rod and to the tag axle, wherein the pivot members rotate from the connection with the pivot rod in the direction of rotation of the pivot rod; andone or more actuating cylinders associated with the actuator and further connected at one end to a control device in the harvester for controlling extension and retraction of the one or more actuating cylinders and connected at another end to the tag axle; wherein when the one or more actuating cylinders are retracted, the one more actuating cylinders pull the tag axle away from the ground surface with the one or more pivot members rotating in direction of the pivot rod to allow for the tag axle to raise up and wherein when the one or more actuating cylinders are extended, the one or more actuating cylinders push the tag axle towards the ground surface with the one or more pivot members rotating in opposite direction with the pivot rod to allow for the tag axle to lower down. 3. The harvester of claim 2, wherein the one or more actuating cylinders are selected from a hydraulic actuator, an electro-mechanical actuator, a mechanical actuator, or a pneumatic actuator. 4. The harvester of claim 2, wherein the one or more actuating cylinders are retracted to pull up the tag axle into a position for storage about the rear of the harvester. 5. The harvester of claim 2, wherein the control device is located in a cabin of the harvester and wherein the control device is selected from a lever, button, switch, or touch display to extend and retract the one or more actuating cylinders. 6. The harvester of claim 1, wherein the tag axle assembly further comprises a tie rod connected between two or more tag tires so that the two or more tag tires caster in the direction of travel of the harvester. 7. The harvester of claim 1, wherein the one or more tag tires contact the ground surface to support loads about the rear end of the harvester when a light weight header is attached at the connection point with the feeder. 8. The harvester of claim 1, wherein the header weighs within a range of 3,000 lbs. to 15,000 lbs. 9. The harvester of claim 1, wherein a tag tire of the tag axle assembly has a larger diameter than other tires of the rear axle assembly. 10. The harvester of claim 9, wherein the tag tire with the larger diameter has a larger width than other tires of the rear axle assembly. 11. The harvester of claim 1, wherein the header is a corn header.
