Emission Reduction


The Toro Company has worked with its suppliers to use engines compliant with applicable worldwide exhaust and evaporative emission standards set by the U.S. Environmental Protection Agency (EPA), California Air Resources Board (CARB), and the European Union.

Emission ReductionDiesel-powered equipment:

  • The Environmental Protection Agency (EPA) Tier 4 emissions regulations for non-road diesel engines (25-74 horsepower) took effect January 1, 2013. These regulations require particulate matter emissions to be reduced 90 percent, plus additional reductions in Nitrogen Oxides emissions.

  • To ensure compliance with these emissions regulations, Toro has partnered with Yanmar America to supply Tier 4 compliant engines.


Gasoline-powered products:

  • EPA Phase 3 emission standards for small off-road engines, implemented during 2011 and 2012, have reduced exhaust hydrocarbons by roughly 35 percent and evaporative emissions by about 45 percent.

  • Our product specifications have been changed in accordance with EPA and CARB guidelines to incorporate low permeation fuel lines and tanks, sealed and tethered fuel caps, carbon canisters, and other modifications.
