The Vermeer FlexTrack 75 is a versatile, compact tracked vehicle designed for a variety of tasks, from trenching to landscape work. Known for its impressive power and reliability, this piece of equipment is frequently used in applications where maneuverability in tight spaces is essential. However, like any complex machinery, it can encounter mechanical issues. One common problem faced by operators of the Vermeer FlexTrack 75 is when the machine won’t turn, causing frustration and delays in the workflow. Understanding the potential causes of this issue and knowing how to address them is critical for maintaining productivity and ensuring the equipment's longevity.
Overview of the Vermeer FlexTrack 75
The Vermeer FlexTrack 75 is engineered for both efficiency and ease of operation. Its rubber-tracked design provides enhanced traction, making it ideal for soft or uneven ground conditions. The machine is powered by a robust engine, and its advanced hydraulic system ensures smooth operation in a variety of challenging tasks.
Despite its reliability, the FlexTrack 75, like other tracked vehicles, can face issues with its steering system. The turning mechanism is integral to its functionality, and when it malfunctions, it can severely impact performance. Addressing these problems quickly and accurately is essential to avoid costly repairs and downtime.
Common Causes of Steering Problems in the Vermeer FlexTrack 75
When a Vermeer FlexTrack 75 fails to turn, there are several potential causes that could be behind the issue. Understanding these causes will help operators diagnose and fix the problem more efficiently.

1. Hydraulic System Issues
   • The FlexTrack 75 relies heavily on its hydraulic system for steering. If the hydraulics are not functioning correctly, the machine will struggle to turn. Some common hydraulic-related problems include low hydraulic fluid levels, air in the hydraulic lines, or worn-out hydraulic components.
     • Low Hydraulic Fluid: Insufficient hydraulic fluid can cause the steering to become unresponsive. Regularly check the fluid levels and ensure the system is properly filled with the manufacturer-recommended fluid.
       
     • Air in the Lines: Air trapped in the hydraulic lines can cause the system to behave erratically, including failure to turn. Bleeding the lines can help restore proper function.
       
     • Worn Hydraulic Components: Over time, hydraulic valves, pumps, and cylinders can wear out. These parts should be inspected regularly and replaced when needed.
       
2. Steering Drive Motor Failure
   • The steering drive motors are responsible for turning the tracks. If one or both of the motors are malfunctioning, it can prevent the machine from turning. Motor failure can occur due to internal wear, contamination of hydraulic fluid, or a broken connection.
     • Motor Wear: Over time, the internal parts of the steering drive motors may wear out, leading to reduced performance. Regular maintenance and timely replacement of worn parts are crucial.
       
     • Contaminated Hydraulic Fluid: Contaminants in the hydraulic fluid can cause damage to the steering motors. Ensuring clean fluid and maintaining the filtration system is essential to prevent motor damage.
       
     • Broken Connections: Loose or broken connections to the motors can interrupt the flow of power, preventing the tracks from turning. These connections should be inspected and tightened regularly.
       
3. Track or Tension Issues
   • If the tracks are too tight or too loose, it can cause problems with turning. Track tension should be checked periodically, as incorrect tension can lead to premature wear of both the tracks and the drivetrain.
     • Track Tension: The tracks should have proper tension to ensure smooth operation. Too tight a track can increase strain on the machine's engine and steering, while a loose track can slip and prevent turning.
       
     • Obstructions in the Tracks: Sometimes, debris or dirt can get lodged in the tracks or undercarriage, causing the tracks to stick or drag. Cleaning the tracks regularly will help prevent these issues.
       
4. Electrical System Problems
   • Electrical issues can sometimes interfere with the operation of the steering system, particularly if there are sensors or electronic components involved. A faulty sensor or an issue with the wiring can cause the machine to fail to respond to steering inputs.
     • Faulty Sensors: Some models may have electronic sensors that control the steering system. If these sensors fail, the steering may not engage properly. Diagnosing the sensors with a diagnostic tool can help identify the issue.
       
     • Wiring Problems: Loose or damaged wiring can cause intermittent steering issues. Inspecting the wiring and connectors for damage or corrosion can prevent these problems.
       
5. Control Valve Malfunctions
   • The steering control valve directs the hydraulic fluid to the appropriate steering motor. If the valve is malfunctioning, it may not direct the fluid properly, preventing the machine from turning.
     • Clogged Control Valve: Over time, dirt and debris can clog the control valve, restricting fluid flow. A thorough cleaning or replacement of the valve may be necessary.
       
     • Internal Valve Damage: If the valve's internal components become damaged, it may fail to function properly. Regular inspection of the control valve can prevent such failures.
       

Steps for Troubleshooting the Turning Issue
If your Vermeer FlexTrack 75 won’t turn, follow these steps to diagnose the issue:

1. Check Hydraulic Fluid Levels
   • Ensure the hydraulic fluid is at the proper level and that it is clean and free from contaminants. Top up the fluid if necessary, and consider flushing the system if the fluid appears dirty or contaminated.
     
2. Inspect the Steering Drive Motors
   • Examine the steering drive motors for signs of damage, leaks, or wear. Listen for any unusual noises when operating the machine, as this can indicate motor problems. If necessary, replace the motors or their components.
     
3. Verify Track Tension
   • Check the track tension and adjust it according to the manufacturer’s specifications. Make sure the tracks are properly aligned and free from obstructions that could impede their movement.
     
4. Inspect the Electrical System
   • Inspect any electrical components, including sensors and wiring, that could be affecting the steering. Use a diagnostic tool to check for error codes related to the steering system.
     
5. Examine the Control Valve
   • Inspect the steering control valve for any blockages or damage. If the valve is clogged or damaged, clean or replace it as needed.
     

Preventative Maintenance Tips
To prevent steering issues on the Vermeer FlexTrack 75, it is important to maintain the machine regularly:

• Regular Hydraulic Fluid Checks: Monitor hydraulic fluid levels and condition regularly to ensure the system remains in good working order.
  
• Track Maintenance: Inspect and adjust track tension periodically, and keep the tracks free from debris.
  
• Component Inspections: Regularly inspect the steering drive motors, control valve, and electrical system to catch issues before they become serious problems.
  

Conclusion
The Vermeer FlexTrack 75 is a powerful and versatile machine, but like all equipment, it can experience issues that affect its performance. If the machine is not turning, the problem could be due to a variety of factors, including hydraulic system malfunctions, track issues, motor failures, or electrical faults. By performing regular maintenance, troubleshooting effectively, and addressing issues promptly, operators can ensure that their FlexTrack 75 continues to operate at its best, minimizing downtime and maximizing productivity.
