Subaru Launches Vertical Shaft Engine for Lawnmowers

The new EA175V Engine from Subaru is the first in its extensive engine line ideally suited for use with walk-behind lawnmowers. Featuring an innovative and completely original design, the engine is built lightweight, yet rugged and powerful enough for demanding mower applications, and is also designed for use on a variety of other vertical-shaft engine applications. By incorporating industry-leading technology and numerous advanced features, the vertical shaft, 174 cm3 displacement engine offers superior power and reliability when compared to competitive engines.

Subaru’s EA175V is the first to bring chain-driven overhead cam (OHC) technology to the small, air-cooled, vertical shaft engine market, allowing it to offer easier starts, quieter operation and more power than similar-class engines. OHC technology combined with a highly efficient hemispherical combustion chamber allow the intake and exhaust valves to be positioned to offer lower resistance for the air/fuel mixture flow, thus optimizing engine performance. This allows the engine the ability to utilize a high compression ratio, thus producing higher power and torque.

Durable, high-quality materials and added features are included to extend engine life. Heavy-duty piston rings and a cast-iron cylinder liner reduce engine wear, while a patent-pending oil delivery system increases longevity. Cooling fins and air circulation have been engineered to optimize cooling capacity to effectively reduce heat and further enhance engine life. The EA175V offers a perfect balance of easy starts in cold weather and superior cooling, making it ideal for lawnmowers and other pieces of multi-seasonal outdoor power equipment.

For use with lawnmower applications, an aluminum alloy flywheel ensures smooth engine operation. The low-mount configuration combined with the aluminum alloy construction furthers the engine’s lightweight design. The flywheel also features a safety brake, which, when released, automatically stops the mower blade within three seconds. For all other equipment applications, a high-mass flywheel is standard.

Subaru Industrial Engines are manufactured by Fuji Heavy Industries Ltd., Japan. Fuji Heavy Industries is a diversified manufacturer of Subaru automobiles, aircraft, ecotechnologies and industrial engines and equipment. Subaru engines are marketed and supported in North America by Robin America, Inc., a subsidiary of Fuji Heavy Industries.

Subaru Industrial Engines will be exhibiting at CONEXPO-CON/AGG 2011.
