The Craftsman 120, the Cub Cadet RT and the Troy-Bilt Bronco are some good small tillers. Some small tillers are electrically powered, while others use conventional gasoline engines.
Craftsman's 120-volt electric trimmer has push-button controls, and it operates quietly while generating none of the odors or harmful emissions that their gas-powered counterparts do. Its tilling width is adjustable from 6 to 10 inches, but its cutting depth is fixed at 5 inches. With a light weight of 22 pounds, it is good for garden bed maintenance but large areas may take several passes.
The Cub Cadet and Troy-Bilt small tillers are both gasoline-powered, more powerful and more expensive. Both tillers have a wider cutting path and a deeper tine reach, which makes them suitable for larger tasks.
