The Troy-Bilt TB210 21" Self Propelled Gas Lawn Mower features a dependable 159cc OHV Check, Don't Change™ engine. Simply check the oil level with each use and top off as needed – no more oil changes! This significantly reduces maintenance time and gets rid of the hassle of disposing old oil. In addition, the deck wash adaptor allows users to connect a standard garden hose to rinse grass clippings from the underside of the deck with ease. This mower also features variable speed front wheel drive which improves control and helps make faster turns. The integrated TriAction® cutting system makes lawns look well-groomed while the rake bumper, specialized blade & symmetrical deck work together to create finely mulched clippings and clean, even cuts every time. With a 1.9-bushel capacity, the rear grass bag makes clean up or composting fast and easy! Troy-Bilt mowers have been built in the USA with global parts since 1937.
