The soil aeration apparatus of claim 1, wherein the handle is connected to the frame forward of the rear roller and rear of the front roller, wherein the handle extends at an angle upward and back from the frame. 3. The soil aeration apparatus of claim 1, wherein the aeration rotor has a radius extending from the first axis to each of the second and third axes of between about 3 inches to about 4 inches, wherein at least some of the plurality of aeration tines have a length exceeding the radius, wherein the soil aeration apparatus weighs between about 200 pounds and about 300 pounds. 4. The soil aeration apparatus of claim 1, wherein the aeration rotor has a radius extending from the first axis to each of the second and third axes of between about 2 inches to about 6 inches, wherein at least some of the plurality of aeration tines have a length exceeding the radius, wherein the soil aeration apparatus weighs between about 100 pounds and about 500 pounds. 5. The soil aeration apparatus of claim 1, wherein the soil aeration apparatus further comprises a relief spring system connected between the motor and the aeration rotor, wherein the relief spring system comprises a first spring, a second spring, and a linkage, and wherein the relief spring system has a spring capacity that is greater than the weight of the soil aeration apparatus such that the soil aeration apparatus is lifted before the relief spring reaches a maximum limit when the aeration tines strike an object. 6. The soil aeration apparatus of claim 1, and further comprising means for driving the aeration rotor. 7. The soil aeration apparatus of claim 1, and further comprising means for containing soil plugs within a rotor cavity, allowing soil particles from broken soil plugs to pass out of the rotor cavity, and allowing for ingress and egress of the aeration tines during rotation of the aeration rotor. 8. The soil aeration apparatus of claim 1, wherein the aeration rotor has only the first and second tine-holder shafts without any additional tine-holder shafts and wherein rotation of the first and second tine-holder shafts causes the aeration tines to sweep through a central portion of the aeration rotor. 9. The soil aeration apparatus of claim 1, wherein the motor is operably connected to the first and second tine-holder shafts to rotate the first and second tine-holder shafts with respect to the first and second carriers. 10. The soil aeration apparatus of claim 1, wherein rotation of the first and second tine-holder shafts causes the aeration tines to sweep through a central portion of the aeration rotor. 11.
