National and online dealers of Troy-Bilt rototillers include Lowe's, Sears and TillersDirect.com. Local dealers can be found using the company website's dealer locator, including Webster County Tractor in Strafford, Missouri; Pocahontas Equipment Company in Pocahontas, Iowa and Beaver Mower, Inc in Des Moines, Iowa.
All of the dealers carry the full line of Troy-Bilt's lawn and gardening equipment, but pricing and models in stock may vary by store. The company's rototiller line has numerous models that range in price from around $500 to almost $2,500, as of 2015. The pricing is usually dictated by the unit's motor size, tilling width and features.
Making the correct selection of the proper tiller depends on several factors, including the size of the garden to till, the type of soil, the garden layout and whether it is a new or existing garden. Front-tine tillers are usually selected for gardens less than 5,000 square feet that have existing patches needing to be maintained. Rear-tine models, however, are best for new plots or large gardens up to 10,000 square feet.
Engine sizes range from 160 to 305 cubic centimeters, and the larger engines are not always more expensive. Tilling width sizes are 14, 16 and 20 inches. The wider till widths reduce the time required to cover the same area as smaller sizes, but they do cost more.
