FAQ
What type of lawn mower should I choose for my yard?
The best type of lawn mower for you will depend on the size and terrain of your yard. For small yards, a manual reel mower is a great option as it is environmentally friendly and requires no gasoline. However, for larger yards, a gas-powered mower may be a better choice as it can cover more ground quickly. Electric mowers are also a good option for smaller yards as they are quieter and cleaner than gas-powered mowers. Ultimately, the best type of lawn mower for you is the one that best suits your needs and preferences.
How often should I tune up my lawn mower?
It is generally recommended to tune up your lawn mower once a year, preferably before the start of the mowing season. This will help to ensure that your mower is running smoothly and efficiently. However, if you notice any problems with your mower, such as a decrease in power or an increase in noise, you should take it in for a tune-up sooner rather than later.

If you are not comfortable checking these components yourself, you can take your mower to a local lawn mower repair shop.
