Just was reading nunns basic chess endings and I think it is a draw but black has to get his king into the action.

6...Nxa6 or 6...Kb6

If you can't hold off three lone pawns with a king + knight, you need to think about the moves more carefully because it should be very easy.

can you please post a game

Your first post isn't even a win for white in the final position, but you're right that the knight can't stop the pawns by itself.

Source for that post I forgot to mention was out of John Nunn's Understanding Chess Endgames.

I have been in a similiar position but my game ended as a draw....

wow
