PERFORMANCE CURVES
FEATURES and BENEFITS
Emissions
The D1503-M engine complies with 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 D1503-M 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’s original E-TVCS (Three Vortex Combustion System) has
been improved. The airflow, combustion chamber, and piston
recess have been optimized to provide low particulate matter
(PM) levels, matching the stringent level of the 37 kW class and
higher (EPA Interim Tier 4 Option 1).
The half-float valve cover and MoS2-coated pistons reduce noise
levels compared to conventional diesel engines and decrease
vibrations transmitted from the valve area, providing enhanced
noise reduction.
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.
