1. Overview of the Issue
The 2020 Kubota SVL75-2 is a compact track loader known for its high-performance capabilities, including the high-flow hydraulic system that provides additional power for operating attachments. However, some users on Panswork reported an issue with the lift arms and bucket curling functions, particularly under high-flow conditions. This problem has raised concerns about the overall effectiveness of the machine in demanding tasks that require full hydraulic power.
2. Symptoms of the Problem
The weak high-flow lift arms and slow bucket curl issue with the 2020 Kubota SVL75-2 can typically be attributed to problems with hydraulic pressure, blockages, or fluid contamination. Regular maintenance, including inspecting the hydraulic system, checking fluid levels, and cleaning or replacing any damaged components, will help ensure the machine performs at its best. Keeping the high-flow system in good working condition is crucial for maintaining the loader's power and efficiency in demanding tasks.
This article summarizes the common issues discussed on the Panswork forum and provides practical solutions for resolving the weak high-flow lift arms and bucket curl problems on the Kubota SVL75-2.

This problem has raised concerns about the overall effectiveness of the machine in demanding tasks that require full hydraulic power.
2. Symptoms of the Problem
- Weak High Flow Operation
Operators have noticed that when using high-flow attachments or trying to lift heavy loads, the lift arms seem weak. The high-flow hydraulic system doesn’t provide the expected power, resulting in slow or limited arm movements.
- Slow Bucket Curling
Another complaint is that the bucket curling function is sluggish, and in some cases, it does not curl to the desired position even with full control input. This could affect the loader's ability to perform tasks such as grading or scooping.
- Hydraulic Pressure Issues
A weak high-flow system may indicate a problem with the hydraulic pressure. If the pump is not delivering sufficient pressure, it can affect the lift arms and the bucket curl. This could be caused by a malfunction in the hydraulic pump, low fluid levels, or air trapped in the hydraulic lines. Operators should check the hydraulic fluid level and ensure that the pump is operating at the correct pressure.
- Blockage or Restrictions in Hydraulic Lines
Another possible cause of weak high-flow performance is a blockage or restriction in the hydraulic lines. Clogged filters, dirty hoses, or kinks in the lines can restrict the flow of hydraulic fluid, reducing the system’s efficiency. Inspecting and cleaning the hydraulic system, including the lines, filters, and valves, is necessary to resolve this issue.
- Faulty Valves or Solenoids
The problem might also stem from faulty valves or solenoids, especially those controlling the high-flow hydraulic system. If these components are damaged or malfunctioning, they can affect the performance of the lift arms and bucket curl functions. Replacing or repairing any malfunctioning components will restore full functionality.
- Hydraulic Fluid Contamination
Contaminated hydraulic fluid can lead to poor system performance, including weak lift arm operation and slow bucket curling. Ensure that the hydraulic fluid is clean and free of debris. Regular fluid changes and filter replacements will help prevent contamination and ensure smooth operation.
- Regular Hydraulic System Checks
Conduct regular checks on the hydraulic system, paying attention to fluid levels, pressure settings, and any signs of leaks. Keeping the hydraulic system in optimal condition will prevent issues like weak high-flow performance.
- Hydraulic Oil and Filter Changes
Follow the manufacturer’s recommendations for changing hydraulic oil and replacing filters. Clean oil is essential for maintaining the power and efficiency of the high-flow system.
- Inspect Hydraulic Lines and Components
Regularly inspect the hydraulic lines, valves, and solenoids for any signs of wear, damage, or blockages. Clean or replace parts as needed to ensure proper flow and pressure in the system.
