The EZTrak Z425 is one of John Deere's top-selling riding lawn mowers for residential use. It is a zero-turn-radius mower, meaning you can maneuver it easily around flower beds and other lawn features. The mower's control levers are within reach, and you can adjust them to make operating your mower even easier. Starting the EZTrak Z425 may take patience if you are performing a cold start, but don't rush it, as doing so could damage the engine.
