Do you have to put the choke on to start a lawn mower?

Whether you need to use the choke to start a lawn mower depends on the specific model and its engine type. Generally, if it's a cold start, using the choke helps enrich the fuel mixture, making it easier to start the engine. However, some modern mowers have automatic chokes and don’t require manual adjustment. Always refer to the owner's manual for specific instructions for your mower.
