A bale lift device is provided by the invention. The bale lift device includes a back frame, a spear member, and rotation axis. The back frame includes a first end, a second end, and at least one extension separating the first end from the second end. The back frame includes a first area for attaching to the loader hydraulic cylinder of a front end loader. The back frame includes a second area for attaching to the loader arm of a front end loader. The spear member includes at least one spear having a first end for penetrating a bale and a second end attached to the back frame. The rotation axis allows the spear member to rotate relative to the back frame. A front end loader having a bale lift device and a method for transporting a bale are provided. A method of assisting the removal of a bale lifting device from a bale without additional levers or hydraulic controls or hydraulic cylinders is provided. The method can utilize the controls already existing in the operational functions of the loader.

We claim: 1. A bale lift device comprising: (a) a back frame having a first end and a second end, and being constructed for attachment to a loader arm and to a hydraulic cylinder attached to the loader arm; (b) a stabilizing member and a plurality of teeth extending from the stabilizing member, and
We claim: 1. A bale lift device comprising: (a) a back frame having a first end and a second end, and being constructed for attachment to a loader arm and to a hydraulic cylinder attached to the loader arm; (b) a stabilizing member and a plurality of teeth extending from the stabilizing member, and wherein the plurality of teeth are constructed for spearing a bale; and (c) a rotation axis attached to the back frame and the stabilizing member to allow rotation of the back frame relative to the stabilizing member as a result of extending or retracting the hydraulic cylinder attached to the loader arm so that when the bale lift device holds a bale and the hydraulic cylinder extends, the back frame first end pushes against the bale as a result of rotation of the back frame relative to the stabilizing member. 2. A bale lift device according to claim 1, wherein the back frame first end comprises a first end stabilizing member, and the back frame second end comprises a back frame second end stabilizing member. 3. A bale lift device according to claim 2, wherein the back frame further comprises back frame extensions for holding the first end stabilizing member and the second end stabilizing member in place. 4. A front end loader comprising: a pair of hydraulic cylinders and a pair of loader arms; a bale lift device attached to the pair of hydraulic cylinders and the pair of loader arms, wherein the bale lift device comprises: (a) a back frame having a first end and a second end, and being constructed for attachment to the pair of loader arms and to the pair of hydraulic cylinders attached to the loader arm; (b) a stabilizing member and a plurality of teeth extending from the stabilizing member, and wherein the plurality of teeth are constructed for spearing a bale; and (c) a rotation axis attached to the back frame and the stabilizing member to allow rotation of the back frame relative to the stabilizing member as a result of extending or retracting the pair of hydraulic cylinders attached to the pair of loader arms so that when the bale lift device holds a bale and the pair of hydraulic cylinders extend, the back frame first end pushes against the bale as a result of rotation of the back frame relative to the stabilizing member. 5. A front end loader according to claim 4, further comprising a quick attachment device having a first member and a second member provided for rapid attachment and detachment, the first member being attached to the bale lift device and the second member being attached to the pair of hydraulic cylinders and the pair of loader arms. 6. A bale lift device according to claim 4, wherein the back frame first end comprises a first end stabilizing member, and the back frame second end comprises a back frame second end stabilizing member. 7. A bale lift device according to claim 6, wherein the back frame further comprises back frame extensions for holding the first end stabilizing member and the second end stabilizing member in place. 8. A method for transporting a bale, the method comprising: engaging a bale with a bale lift device provided on a front end loader of a tractor, wherein the front end loader has left and right attachment hydraulic cylinders and left and right loader arms, and the bale lift device is attached to the left and right attachment hydraulic cylinders and the left and right loader arms, the bale lift device comprising: (a) a back frame having a first end and a second end, and being constructed for attachment to the left and right loader arms and to the left and right cylinders attached to the left and right loader arms; (b) a stabilizing member and a plurality of teeth extending from the stabilizing member, and wherein the plurality of teeth are constructed for spearing a bale; (c) a rotation axis attached to the back frame and the stabilizing member to allow rotation of the back frame relative to the stabilizing member as a result of extending or retracting the pair of hydraulic cylinders attached to the left and right loader arms so that when the bale lift device holds a bale and the left and right attachment cylinders extend, the back frame first end pushes against the bale as a result of rotation of the back frame relative to the stabilizing member; and moving the bale to a new location. 9. A method according to claim 8, further comprising a step of disengaging the bale from the bale lift device. 10. A method according to claim 9, wherein the step of disengaging comprises extending the left and right hydraulic cylinders to cause the back frame and the plurality of teeth to rotate relative to each other. 11. A method according to claim 8, wherein the back frame first end comprises a first end stabilizing member, and the back frame second end comprises a back frame second end stabilizing member. 12. A method according to claim 8, wherein the back frame further comprises back frame extensions for holding the first end stabilizing member and the second end stabilizing member in place.
