At Troy-Bilt, our history is a source of deep and ongoing pride. We pioneered the first residential rototiller back in 1937 and for over 80 years, our passion for tillers has stayed straight as an arrow. Most Troy-Bilt rear tine tillers have a cast-iron encased, bronze gear transmission that is engineered for heavy duty performance and is covered by a limited lifetime warranty. Rear tine tillers are best for breaking new ground and powering through hard-packed, challenging soil in medium to large garden beds. Front-tine tillers and cultivators are more compact, making them best for tasks in small to medium existing garden beds. If clearing leaves, sticks and other debris from your yard is a priority, Troy-Bilt's chipper shredders and chipper vacuums can make that easier and provide nutrient-rich garden mulch or compost at the same time. The chromium steel chipper blades and cast-steel flails quickly chip through branches and reduce the amount of yard waste. The Troy-Bilt chipper vacuum features an on-board vacuum hose to help you easily clean out corners, tight spots and under shrubs.
