Skid steers are widely used in construction and agricultural industries due to their versatility and high efficiency. Their unique steering mechanism, which allows them to turn in tight spaces, makes them incredibly useful for various tasks. However, sometimes skid steers may encounter issues with turning, especially when they fail to counter-rotate. This problem is typically related to the hydraulic system, and addressing it is key to restoring the machine’s functionality.
Problem Description
When a skid steer fails to counter-rotate, it means the machine is unable to perform its normal turning function, particularly when both sides of the machine should be rotating in opposite directions. This issue is generally caused by a hydraulic failure. Normally, skid steers use a differential between the speeds of the left and right drive motors to steer the machine. When the hydraulic system fails, this control is lost, and the machine will not be able to steer properly or at all.
Common Causes
The failure of a skid steer to counter-rotate is often a hydraulic issue, typically involving low or contaminated hydraulic fluid, pump failure, valve malfunctions, or issues with the drive motors. Regular maintenance and timely troubleshooting of the hydraulic system can help prevent such problems. By diagnosing and repairing hydraulic system failures promptly, you can ensure that the skid steer continues to perform reliably, minimizing operational delays and costly repairs.

Common Causes
- Low or Contaminated Hydraulic Fluid: The hydraulic system depends on high-quality fluid to operate the motors and actuators. If the hydraulic fluid is low or contaminated, it can cause unstable hydraulic pressure, affecting the responsiveness and efficiency of the drive motors.
- Hydraulic Pump Failure: The hydraulic pump is the heart of the hydraulic system, responsible for generating the necessary pressure to operate various components. If the pump fails or is damaged, the system won't generate enough pressure to drive the skid steer in the desired direction.
- Hydraulic Valve Sticking or Malfunction: The hydraulic valve regulates the oil flow, controlling the direction and speed of the drive motors. If the valve becomes stuck, damaged, or requires cleaning, the control signals may not be transmitted properly, leading to a failure in counter-rotation.
- Drive Motor Issues: Each drive motor is responsible for driving one side of the skid steer. If a drive motor malfunctions or has internal damage, it may result in poor steering control or a complete inability to counter-rotate.
- Hydraulic Line Leaks: Any leaks in the hydraulic system will cause oil loss, leading to reduced system pressure. This can affect the drive motors' performance and prevent proper steering.
- Check Hydraulic Fluid: Begin by checking the fluid level and condition. If the hydraulic fluid is low or contaminated, replace or top it off with fresh, high-quality fluid. Ensure the system is clean and free of contaminants.
- Inspect the Hydraulic Pump: Check the hydraulic pump for proper operation. If the pump is failing to generate stable pressure, it may need to be repaired or replaced.
- Examine Hydraulic Valves and Lines: Inspect the hydraulic valve for any signs of sticking or malfunction. Clean or replace the valve if necessary. Also, check all hydraulic lines for leaks or blockages, ensuring oil flows freely through the system.
- Check Drive Motors: Inspect the drive motors for any signs of failure or internal damage. If the motors are faulty, they may need to be disassembled and repaired or replaced.
- Perform a Pressure Test: Conduct a pressure test on the hydraulic system using a pressure gauge. If the pressure is below the specified level, this may indicate a problem with the pump or another component of the system that needs further investigation.
- Regular Hydraulic System Checks: Regularly inspect the hydraulic fluid level, quality, lines, and valves to ensure the system is operating smoothly. Catching problems early can prevent costly repairs and downtime.
- Use High-Quality Hydraulic Fluid: Always use the recommended hydraulic fluid for your skid steer and keep the system clean. This helps prevent damage to the hydraulic components and ensures the system works efficiently.
- Routine Drive Motor Maintenance: Periodically inspect and maintain the drive motors to avoid wear and tear that can affect the skid steer’s steering capabilities.
