A rotary soil cultivator manufactured by MTD Products under the Yard Machines brand is a common tool for garden preparation. These gasoline-powered machines use rotating tines to break up and aerate soil, making it suitable for planting. A typical example features a set of adjustable tines, powered by a compact internal combustion engine, and controlled by a set of handlebars.
Soil cultivation improves drainage, nutrient absorption, and root development, leading to healthier and more productive plants. The mechanization of this process, beginning in the early 20th century, revolutionized agriculture and home gardening. This type of equipment allows gardeners to prepare larger areas for planting more efficiently than manual methods. This reduces labor and time required for soil preparation, particularly for large gardens or tougher soil types. The benefits extend to weed control, as the tilling action disrupts weed growth.
