Your mower can be smoking for a number of reasons. First check your oil level and your spark plug. Next check your air filter. If the spark plug is not properly gapped this usually causes smoking on start up.

The smoke might be from oil that gets past the rings into the cylinder. When you start it up after it has been sitting the oil gets burned off causing the smoke only when you start it.

Lawn tractors usually smoke when they are in need of an oil change. To get it to stop smoking change the oil. If you just changed your oil and it started smoking then you probably added too much oil. All you need to do is drain some oil out of the crankcase.
