The Toro TimeCutter® SS5060 zero turn model features a 23 hp 726cc Kawasaki V-Twin engine and 50? deep, dome mowing deck with a convenient washout port for under deck cleaning. It also features the Smart Speed® control system -- giving you greater control of speed and maneuverability. Shift to Mow & Tow for a higher speed range to cut large, open areas quickly or to drive from one end of your yard to the other. Shift to Trim & Tow for a slower speed range with more precise control for trimming around delicate areas or for properly pulling attachments.
