Self-propelled mowers are lawn care machines designed to move forward on their own, making it easier for users to cut grass without needing to push them. They typically have a drive system that allows the mower to adjust its speed based on the user's walking pace, providing a more comfortable mowing experience. These mowers come in various types, including gas-powered and electric models, catering to different preferences and yard sizes. Many self-propelled mowers also feature adjustable cutting heights and mulching capabilities, allowing users to customize their lawn care routine while ensuring a neat and healthy lawn.
