As well as making walk-behind mowers and garden tractors, Simplicity also make a good range of zero-turn mowers. The Simplicity Axion zero-turn mower is one of them. If you buy it new, you can choose between two engines. An 18. 5hp or 21hp Briggs & Stratton Extended Life Series engine (which, as you’ll probably guess from the name, is designed to have a longer life than similar engines of the same size). These engines are started with a 12-volt battery that provides the engine with 230 cold cranking amps. The engine is fueled by gasoline from a 11. 4 liter (3 US gallon) tank.
The Simplicity Axion’s transmission transfers power from the engine to the wheels. This is a Hydro-Gear EZT hydrostatic transmission that gives the mower infinite speeds in both forward and reverse. This transmission is also the reason the Axion can execute zero radius turns, as it allows the operator to control each rear wheel independently, using the turn bars. Pushing the lap bars in alternate directions is what allows the operator to make a turn with no radius.
Since the Simplicity Axion’s rear wheels do most of the work, from driving the machine forward to providing traction, as well as supporting the weight of the machine, they are also much larger than the front wheels. The rear wheels each measure 18×8. 5 (18 inches in diameter, 8. 5 inches wide) while the front tires, whose primary job is to keep the mower deck off the ground, are much smaller at 11×4-4 (11-inch diameter, 4-inch width, 4-inch rim diameter). The deck on this model has a 33- or 42-inch width of cut. Similar models are the Simplicity ZT2000 and the Simplicity ZT3000.
