You'll have to do some research. Find out the size of the wire going to the headlights. Get your model and spec number from the engine and found out what the charging system produces. Most mowers also have an electric blade clutch, you'll need to get the model number and find out how much current it draws. Google can answer any questions that you may have like "How do I find out what size wire I have?" To be safe and not draw any more power than you must, and to be assured that the battery will be charged, I wouldn't go over 50% of the rated allowable load between the clutch and headlights.
