A yanker for releasing a trailer from a tractor, the yanker comprising a yanker shaft extending between a first end connected to a yanker handle, and a second end connected to a yanker lever, the yanker lever having a first linear section extending laterally away from the second end of the shaft, and the yanker lever having a second linear section extending laterally from the first linear section in a direction away from the yanker handle, anda yanker hook connected to the yanker shaft proximate the second end on a side of the yanker shaft opposite the yanker lever, the second linear section of the yanker lever pointing generally opposite the direction of the yanker hook, andwherein, when the second linear section of the yanker lever contacts a top surface of a frame of the tractor and the yanker handle is twisted clockwise or counterclockwise, the yanker hook moves upward. 2. The yanker of claim 1, wherein the yanker hook has a first linear segment and a second linear segment connected to the first linear segment, the first linear segment extending laterally outward from a surface of the yanker shaft, and the second linear segment extending at an angle from the first linear segment toward the yanker handle, the second linear segment and the axis of the yanker shaft being skew. 3. The yanker of claim 1, wherein the second linear section of the yanker lever extends parallel to the axis of the yanker shaft. 4. The yanker of claim 3, wherein the yanker lever has a third linear section extending laterally from the second linear section and parallel to the first linear section. 5. The yanker of claim 4, wherein the third linear section has a length that is less than a length of the first linear section. 6. The yanker of claim 4, the yanker having a fourth linear section extending from the third linear section and parallel to the second linear section. 7. The yanker of claim 6, wherein the fourth linear section has a length that is less than a length of the second linear section. 8. The yanker of claim 3, the yanker hook having a first linear segment and a second linear segment connected to the first linear segment, the first linear segment extending laterally outward from a surface of the yanker shaft, and the second linear segment extending at an angle from the first linear segment toward the yanker handle, the second linear segment and the axis of the yanker shaft being skew. 9. A yanker for releasing a trailer from a tractor, the yanker comprising a yanker shaft extending between a first end connected to a yanker handle, and a second end connected to a yanker lever, anda yanker hook connected to the yanker shaft proximate the second end, the yanker lever pointing generally opposite the direction of the yanker hook,wherein the yanker lever has a first linear section extending laterally from the second end of the shaft, and a second linear section extending laterally from the first linear section and parallel to the axis of the yanker shaft, a third linear section extending laterally from the second linear section and parallel to the first linear section, and a fourth linear section extending from the third linear section and parallel to the second linear section, andwherein, when the second linear section of the yanker lever contacts a top surface of a frame of the tractor and the yanker handle is twisted clockwise or counterclockwise, the yanker hook moves upward. 10. The yanker of claim 9, wherein the third linear section has a length that is less than a length of the first linear section. 11. The yanker of claim 9, wherein the fourth linear section has a length that is less than a length of the second linear section.
