Low Vibration & Low Noise

Superior vibration and noise reduction is achieved through the use of precision balancers. This leads to operating comfort even under long work hours.

Compact, Diesel Injection Engine = Easy Installation & Low Fuel Consumption

Keeping with the tradition of compact design, the new LV series is simple to install. It fits in cramped spaces without sacrificing power and performance. YANMAR’s proprietary direct injection technology allows the engine to sip rather than gorge on fuel. This means lower running cost in the world of rising fuel prices.

Quick and Easy Start

Starting is a breeze with the standard recoil starter. Starter motor and switch are also available as an option.
