Troybilt Super Bronco Tiller


Product Details

The Troy-Bilt 21D-65M8766 Super Bronco 16 in. 208 cc OHV Engine Rear-Tine Counter-Rotating Gas Tiller with One Hand Operation and Power Reverse offers an outstanding value for a small or mid-size garden. The gas tiller gives you counter-rotating technology plus features normally found only on larger models – such as Patented Bolo Tines. Powerful enough to till deeply, yet small enough to fit between rows, the gas tiller is designed to tackle any task in your garden with ease. The power reverse option on the gas tiller allows for flexible handling around rocks and other obstacles. Get the job done right with this counter-rotating gas tiller!

  • All Troy-Bilt rear-tine tillers feature patented Bolo tines, which are 3 uniquely shaped tines; each tine is designed to do a separate task, yet work together to create finely tilled soil, ready for planting
  • Rear-tine gas tiller uses a patented cast-iron encased transmission with bronze gear drive that provides so much extra strength and durability; Troy-Bilt covers it with a limited lifetime warranty
  • 208 cc OHV Troy-Bilt engine packs enough power to turn over large amounts of tough soil
  • Just 1-hand operation lets you guide the gas tiller with literally 1-hand, because the machine is engineered to be well-balanced and easy to control; it does the work not you
  • Counter- rotating tines are best for breaking new ground and power through hard-packed challenging soils
  • Power reverse helps you back out of tight corners and dense soil
  • Larger front bumper provides extra protection from accidental damage to landscaping or the engine
  • Gear-drive transmission with 1 forward speed helps keep gas tiller moving through soil
  • Wider 1 in. handles improve stability and handling
  • Adjust handle height quickly, in the garden, with no tools required
  • Ergonomically designed depth stake handle makes it easier to adjust tilling depth and is more comfortable to use
  • 13 in. agricultural tires enhance traction and maneuverability
  • Addition to gardening, counter-rotating gas tiller can also aid in prepping areas for seeding, mixing compost in the pile or mixing compost into your soil
  • Limited-lifetime warranty on the transmission, including all gears, shafts and housings, against defects in material and workmanship for the life of the tiller (to the original purchaser only)
  • 2-year limited warranty
  • Some assembly required upon delivery
  • California residents see Prop 65 WARNINGS
