PERFORMANCE CURVES

FEATURES and BENEFITS

Emissions

The Kubota Super Mini Series features compact multi-cylinder
liquid cooled industrial diesel engines which comply with EPA /
CARB Tier 4 emissions level.

Durable Power

The Kubota Super Mini Series has been chosen as a power source for a variety of applications. The D722 engine offers a seamless transition from E3 to E4 by maintaining the same level of performance and physical characteristics. Alternative fuel engines WG752-G (gasoline) and WG752-GL (dual fuel: gasoline / LPG) are available with the same footprint as the D722 engine.

Clean and Quiet Power

Kubota’s original E-TVCS (Three Vortex Combustion System) has
been improved. The piston recess has been optimized to achieve
lower particulate matter (PM) levels at an extremely small size.
The half-float valve cover and MoS2-coated pistons reduce noise
levels and decrease vibrations transmitted from the valve area.
