Proportional Flow Control 

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.
You can program up to five different oil flow rates depending on the task at hand and call on them when needed. The system will 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 fuel. AUX1's max flow is now up to 60 litres so you have the convenience of being able to operate more accessories than eve before.
Third Line Hyd Return to Tank
When working with one-way hydraulic attachments, such as a breaker or brushcutter, 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.
Large-Capacity Variable Displacement Pump

Smooth operation is a must when you're working in close quarters. Kubota's unique hydraulic system and large capacity variable displacement pumps put the U35-4's speed and power under smooth, precise control. The performance-matched boom, arm, and bucket movements are the best in the industry and improve job efficiency. With all that hydraulic power harnessed in the front working group, you're guaranteed superior digging force whenever you need it.
