Performance Curves
Features and Benefits
Emissions
The D1703-M-DI engine complies with the EPA/CARB Tier 4 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 D1703-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
The fuel injection pressure has been increased to achieve lower particulate matter (PM) levels. 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. Indirect-Injection engines are also available.
