Draining gas from a lawn mower is an essential maintenance task that every owner should know how to perform properly. Whether you’re preparing your mower for winter storage, performing routine maintenance, or troubleshooting engine issues, removing old gasoline is often necessary. While siphoning is a common approach, many homeowners don’t have siphoning equipment readily available or prefer not to use this messy method. Fortunately, there are several alternative techniques that are just as effective and often cleaner. This comprehensive guide will walk you through multiple safe and practical methods to drain gasoline from your lawn mower without needing a siphon.
