The E-Series is the perfect choice for professional landscape contractors who want the innovative engineering and\commercial-grade quality of a Lazer Z, but in a value package. The E-Series features the same welded, heavy-duty, 1.5" x 3" tubular steel unibody frame found on more expensive Lazer Z models. A digital operator diagnostic module simplifies system monitoring and troubleshooting, while the fuel gauge uses ultrasonic waves to provide a more accurate reading. In short, the Lazer Z E-Series strikes a perfect balance of value and performance.
