Skid Steer Lifting Arms and Bucket Tilt Issue

[MikePhua]

A user on the panswork forum reported an issue with their skid steer when attempting to lift the arms and tilt the bucket down simultaneously. The machine seemed unable to properly handle both actions at the same time, which led the user to believe there might be an issue with the hydraulic system, control system, or another component. The user sought advice on possible causes and solutions for this problem.
Hydraulic System Inspection
The first suspicion was a fault within the hydraulic system. According to forum discussions, issues with hydraulic response and pressure can cause problems when attempting to perform two actions simultaneously. Several users suggested starting with an inspection of the hydraulic oil quality and level. Dirty oil or low oil levels could prevent the hydraulic pump from providing the necessary pressure to handle both actions at once. Additionally, inspecting the hydraulic valves for any blockages or damage was also recommended, as these could affect the machine’s ability to perform multiple tasks simultaneously.
Hydraulic Valve Issues
Hydraulic valves are responsible for directing the flow of hydraulic oil based on control commands. If a valve malfunctions, it could prevent certain actions from occurring at the same time or cause delayed responses. Forum users advised checking the hydraulic valves for the bucket tilt and lifting arms to ensure there were no blockages, wear, or improper adjustments. Any issues with the hydraulic valves could interfere with the machine's ability to perform smooth, multi-functional tasks.
Control System and Electrical Checks
Apart from the hydraulic system, another potential cause for this problem could be issues with the skid steer’s control system. The user reported that the sensitivity of the control levers might not be optimal, making it difficult for the machine to properly interpret and execute commands when multiple actions are required. It was recommended to check the signal transmission between the control levers and the hydraulic system. Electrical wiring issues or sensor malfunctions could lead to unstable hydraulic functions and improper operation.
Additional Recommendations
Other users on the forum suggested regularly inspecting the skid steer's hydraulic lines and connections, especially after extended use. Leaks, loose fittings, or worn hoses could reduce hydraulic efficiency and lead to operational issues. Ensuring that all hydraulic components are in good working condition is crucial to preventing such problems.
Solutions and Recommendations

1. Inspect the Hydraulic System: Check the quality and level of hydraulic oil to ensure it’s clean and at the correct level. Inspect the hydraulic pump and valves for any blockages or damage.
   
2. Check the Hydraulic Valves: Focus on the hydraulic valves controlling the bucket tilt and lifting arms. Ensure they are functioning properly and have no issues with blockage or adjustment.
   
3. Inspect the Control System: Examine the signal transmission between the control levers and the hydraulic system. Ensure there are no electrical wiring issues or sensor malfunctions.
   
4. Regularly Check Hydraulic Lines and Connections: Ensure all hydraulic lines and fittings are leak-free and properly tightened to maintain system efficiency.
   

Conclusion
When a skid steer struggles to lift the arms and tilt the bucket simultaneously, the issue is often linked to the hydraulic system, hydraulic valves, or the control system. By inspecting the hydraulic oil, valves, control system, and connections, users can troubleshoot the problem. Regular maintenance of the hydraulic system components will help maintain the machine’s performance and prevent recurring issues.
