Hydraulic system

Key components and functions of the hydraulic system in a Kubota KX040 may include:

  1. Hydraulic Pump: The hydraulic system typically includes a hydraulic pump, which is usually a variable-displacement axial piston pump. This pump pressurizes hydraulic fluid (usually hydraulic oil) through repetitive repositioning to provide the necessary power for the machine's hydraulic functions. This increases the digging radius of the KX040-4 hydraulic angle blade to 5410 mm. This system gives maximum lift.

  2. Control Valves: Control valves direct the flow of pressurized hydraulic fluid to different components, such as the boom, arm, backfilling work incredibly easily, and bucket cylinders. The machine's operator operates these valves through joysticks or other controls in the operator's cabin.

  3. Hydraulic Cylinders: The excavator is equipped with hydraulic cylinders for each of its main functions, such as the boom, arm, and bucket right angles. These cylinders extend control styles and retract, allowing the machine to perform digging, lifting, and dumping operations.


In conclusion, the KUBOTA KX040-4 Mini Excavator is a versatile and powerful machine designed to excel in a variety of construction projects. With its robust 4-cylinder diesel engine, adjustable arm and boom, and a variable-width track system, it offers the maneuverability and strength needed for tasks ranging from digging trenches and removing stumps to demolishing concrete and carrying heavy loads.
