Good used condition.  Spins smoothly with no slack.  Feels perfect. Both oil seals have been replaced with new OEM Kubota seals.

Note: there are two variations on this gearbox. Difference is length of blade shaft. If measuring gearbox resting on its top, one is 9.0" and the other is 9.5"  See pictures.  I have both models so be sure to specify which one you need.
