This is a rear-wheel drivetrain that is supposed to automatically sense the speed of the operator and match it. It still has a Briggs and Stratton engine, with 6.75 ft.-lbs. of gross torque and Ready Start, which means that no priming is required. It uses the Super Recycler cutting system with veneered blade and accelerators. The cutting width is 21" and the deck is made of aluminum, and can discharge clippings to the side, mulch, or optionally bag them. The drivetrain makes the mower heavier than the standard push model, at 77 lbs. Toro suppots the 20091 with a five-year full warranty as well.
