PERFORMANCE CURVES

FEATURES and BENEFITS

Emissions

The V2403-M naturally aspirated engine complies with the EPA /
CARB interim Tier 4 + EU Stage IIIA emissions regulations.

Durable Power

The Kubota 03-M Series is well known for its industrial applications.
With numerous features such as a built-in solenoid, low fan position,
and single-side serviceability, this engine provides excellent
performance and flexibility.
The cooling water passages between the cylinder bores features
Kubota’s original casting technology as a countermeasure against
the heat load caused by high power density, providing both
superior endurance and reliable engine performance.
The V2403-M-DI naturally aspirated engine offers a seamless
transition from EPA Tier 2 to EPA interim Tier 4 by maintaining
the same footprint and hardware mounting points with minimal
performance changes from EPA Tier 2 engines.

Clean and Quiet Power

Kubota has increased the fuel injection pressure to achieve more
complete combustion to reduce particulate matter (PM) levels.
The half-float valve cover and MoS2-coated pistons reduce noise
levels by 1.0-2.0 dBA compared to conventional diesel engines
and decrease vibrations transmitted from the valve area.

Options

Kubota 03-M Series engines offer side power take-off (PTO) in
response to the trend of the use of hydraulic control devices in
industrial machines. A hydraulic pump can be installed at the two
side PTO locations.
Indirect-Injection engines are also available.
