Mowers are machines designed to cut grass and maintain lawns, gardens, and fields. They come in various types, including push mowers, riding mowers, and robotic mowers, each suited for different yard sizes and terrains. Mowers typically use sharp blades to trim grass to a uniform height, promoting healthy growth. Most mowers are powered by either gasoline or electricity. Gasoline mowers are often more powerful and suitable for larger areas, while electric mowers are quieter and more environmentally friendly. Some modern mowers, like robotic mowers, can operate autonomously, navigating around obstacles to keep lawns well-groomed.
