Toro and Yanmar form partnership

The Toro Co. has announced a partnership with Yanmar America Corp. Yanmar will provide diesel engines for select Toro commercial turf maintenance equipment. The Yanmar diesel engines will allow Toro to comply with the U.S. Environmental Protection Agency's Tier 4 emissions regulations, which go into effect Jan. 1, 2013.

The first Toro products to feature Yanmar's Tier 4 compliant diesel engine technology will be select commercial mowers over 25 horsepower. 

Tier 4 is the strictest EPA emissions requirement for off-highway diesel engines. The regulations set specific limits on the amount of pollutants, specifically oxides of nitrogen and particulate matter, that can be released into the environment. The requirements are part of the federal Clean Air Act to reduce air pollution because of its potential hazards to human health and the environment. In May 2004, as part of its Clean Diesel Program, the EPA finalized a comprehensive rule to reduce emissions from non-road diesel engines. The rule consists of four tiers of emissions standards; Tier 4 is the final stage.

"We are pleased with our new partnership with Yanmar," said Darren Redetzke, VP for Toro's Commercial Business. "Toro is confident that our customers will appreciate the state-of-the-art Yanmar diesel engine technology which has been developed to ensure both high quality performance and the cleanest emissions."
