Powermate Front-Tine Gas Tiller
For the most bang for the buck, you can't beat the Powermate (21") 140cc Front Tine Gas Tiller, the lowest priced full size tiller here. Weighing 105 pounds, it comes with 3 adjustable tilling sizes, including 11, 16, and 21-inches. Able to till down to a depth of 8 inches, the Powermate Gas Tiller also comes with a 4 horsepower motor, making it prefect for smaller to medium-sized gardens.
This tiller also has a self sharpening tine feature for keeping blade edges sharp, and the big 8-inch wheels keep it rolling over rough terrain. The reality is that, most suburban gardeners don't need a tiller better than this, and with a 2 year warranty you can't do better for the price.
