 Clean-running Kubota Engine

  • Clean-running Kubota Engine (Interim Tier IV)

Powerful and dependable, the KX91-3S2's diesel engine delivers superior horsepower and performance. It offers low noise and vibration levels, exceptional fuel efficiency and complies with interim Tier IV emissions regulations.


Angle blade

  • Angle Blade (Option)

Save time and work more efficiently. With a simple movement of the dozer lever, the hydraulic angle blade can be angled to the right or the left to push soil to the side as the machiine moves forward, eliminating the need for repetitive repositioning at right angles when backfilling trenches.


Adjustable max. oil flow on auxiliary circuit

  • Adjustable Max. Oil Flow on Auxiliary Circuit

This unique function lets you control the oil flow according to your needs or the attachment in use. It eliminates the hassle of using tools to change settings manually, so you don't have to leave the cabin. When using a tilt bucket, you can slow the flow to get just the right control to gently shape a swale. Alternatively, for a brush cutter, direct the oil flow to one side of the excavator arm. The system will even store your settings for the next time you need it, saving time and quickly regulating the flow requirements. Adjustable oil flow enhances performance and saves fuels.

  • Auto Idle as Standard

Save fuel with Kubota's Auto Idle. Reduce engine RPM instinctively when high engine speed isn't needed. When the control levers are in neutral for more than 4 seconds, the engine RPM automatically idles. Move any control lever and the engine RPM immediately returns. This innovative feature reduces noise and exhaust emissions while reducing operating costs.

  • Metallic Hood

The KX91-3S2 features long-lasting rear and side panels that open easily for quick inspection and routine maintenance. These panel are made of steel for enhanced strength and durability.


Standard third line hydraulic return to tank

  • Standard Third Line Hydraulic Return to Tank

When working with one-way hydraulic attachments, such as a breaker or brush cutter, the standard third-line hydraulic return system allows oil to flow directly back to the tank without running through the control valves. This contributes to less oil contamination, reduced back pressure, and greater oil flow efficiency.
