The new Kubota 07 Series engines have been designed to comply with
EPA Interim Tier 4 (Option1) emissions regulations, which are the
most stringent in this size range. The Kubota 07 Series engines
also comply with EU Stage lllA requirements.
The Kubota 07 Series engines offer the benefit of one year longer
validity than Tier 3. Therefore, these engines are good through the
end of 2012 in both the North American and European markets, which
would save engineering resources for the future Tier levels.
Kubota’s unique cylinder block design was developed using Kubota’s
original casting technology allowing for a larger displacement
within the current 2.4 L compact engine package.
The improved cooling system with a main water gallery and water
passages between cylinder bores as a countermeasure against heat
load provides high power density and superior endurance.
