Sounds to me like a brake is hanging up or water (doesn’t take much) frozen in the rear end on one side. Was the tractor setting level? If not, was the side that the wheel turns the high side? If so it might be water in the rear end that has frozen and preventing the bull gear from turning. If it warms up, loosen the drain plug below the PTO until it is loose enough for water to drip out but not the gear oil. This will temporarily fix this problem.

If the tractor was setting level, then I suspect that a brake has hung up on the side that won’t turn.

The reasoning is based on the following which is assuming the engine is not running and the clutch is engaged. One wheel turning and the other doesn’t means the pinion shaft AND differential spider gears have to be turning. (The differential spider gears must be working for one wheel to turn and the other stand still and since the differential housing must turn when one wheel turns and the other stands still, that means the pinion shaft is turning and the transmission has to be in neutral or the clutch disengaged.)

If the spider gears are locking, both wheels would have to rotate the same direction at the same speed. (Their function is to allow the wheels to rotate at different speeds.)

If the transmission is stuck in a gear, and the differential is working, the wheels will turn opposite directions, since the pinion shaft and differential can’t turn, the spider gears must or neither wheel will turn.
