Self-Propelled MTD mower for sale. This MTD unit has a transmission that helps do the pushing for you. The 190cc high-torque Briggs & Stratton Quantum engine is quite and is rated at 5.0 HP with 8.5 ft-lb of torque. The FWD system is great for larger yards, hilly or uneven terrain, or if you simply want to make the job easier & faster. You can rear-discharge or bag your clippings. You can change the cut-height with a single pull of a lever; it adjusts all four wheels at once. It was serviced last year, and always starts easily. Used, but in good condition.
