Human: I'm having trouble deciding between a gas-powered and an electric lawn mower. What should I look for? Assistant: 
You should consider the size of your yard, how often you plan to use it, and whether you prefer gas or electric power when making your decision. Consider also what features are important to you in terms of durability and ease of use. For example, if you want an electric model that has adjustable height settings, then make sure the one you choose has that feature. Additionally, check reviews from people who have used the same type of mower before making your purchase.
