I would be surprised if you haven't damaged part of the drive mechanism by applying the power tool. That manual drive is meant to be an emergency method of moving the seat by turning the mechanism normally turned by the electric motor. The gears are plastic, and not designed for any significant torque.

However, that isn't what is causing your limited seat motion forward. Something is binding on the track, or both of the threaded rods that the seat travels along are stripped at that point. In any case, your best bet will be to try to apply steady, firm pressure directly to the back of the seat while either turning the mechanism manually or by electric power. Of course, check for anything like carpet or similar obviously preventing the seat from moving at the front. You might want to first move the seat as far back as possible to carefully inspect the condition of the rails at the front.
