New design plastic fuel tank. The fuel tank in the model is plastic. A plastic tank does not attract moisture like a conventional metal tank. So no more corrosion from inside out and no more rough running because you have water in the fuel. New exhaust system. Better quality build and appearance and less dB output. New design front control panel. Again designed and manufactured form plastic for both safety reasons and appearance. Ergonomic in design and very user friendly and easy to use. Supplied with two front wheels and handles that fold away for easy mobility.
