Safe Towing Procedures for the Bobcat S250 Skid Steer Loader

[MikePhua]

Bobcat’s S250 and Its Role in Heavy-Duty Compact Work
The Bobcat S250 skid steer loader was introduced in the early 2000s as part of Bobcat’s high-capacity S-series. With a rated operating capacity of 2,500 lbs and a turbocharged diesel engine producing around 75 hp, the S250 was designed for demanding tasks in construction, demolition, and agriculture. Bobcat, founded in 1947, has sold millions of loaders globally, and the S250 remains a respected model for its power-to-size ratio and hydraulic versatility.
The S250 features a vertical lift path, making it ideal for loading trucks and handling heavy pallets. Its robust frame and auxiliary hydraulic system support a wide range of attachments, but when the machine becomes disabled or needs relocation, understanding the correct towing procedure is essential to avoid damage.
Terminology Notes

• Hydrostatic Drive: A propulsion system using hydraulic fluid to power wheel motors, allowing variable speed and torque.
  
• Tow Valve: A bypass valve that allows hydraulic fluid to circulate freely, enabling the wheels to turn without engine power.
  
• Lift Arm Support Device: A mechanical lock that secures the lift arms during service or transport.
  
• Neutral Position: A state where hydraulic pressure is disengaged, allowing safe towing or movement.
  

Why Towing Requires Caution
The S250 uses a closed-loop hydrostatic system. If the machine is towed without releasing pressure in the drive motors, internal damage can occur. The motors are not designed to be back-driven under load without fluid bypass. Improper towing can lead to:

• Seal failure in drive motors
  
• Overheating of hydraulic fluid
  
• Gear damage due to forced rotation
  
• Brake system strain or lockup
  

In one case, a contractor in Arizona attempted to tow a disabled S250 using a chain and pickup truck. The loader’s wheels resisted movement, and the drive motors were damaged within 100 feet. The repair cost exceeded $3,000 and required full motor replacement.
Step-by-Step Towing Procedure
To safely tow a Bobcat S250:

• Ensure the loader is on level ground and the lift arms are lowered
  
• Engage the lift arm support device to prevent accidental movement
  
• Locate the tow valves on each hydraulic drive motor (usually behind access panels near the rear wheels)
  
• Use a wrench to rotate each tow valve counterclockwise 2–3 turns to open the bypass circuit
  
• Confirm that the wheels rotate freely by pushing the loader slightly
  
• Attach towing chains or straps to the designated tie-down points on the frame
  
• Tow slowly using a vehicle rated for the loader’s weight (~8,000 lbs)
  
• Avoid sharp turns or sudden stops during transport
  
• After towing, close the tow valves by turning them clockwise to restore normal hydraulic function
  

If the loader must be winched onto a trailer, follow the same valve procedure and use ramps with adequate weight rating. Never attempt to tow the machine with the tow valves closed.
Additional Recommendations and Safety Tips

• Use wheel chocks during valve adjustment to prevent unintended movement
  
• Wear gloves and eye protection when working near hydraulic components
  
• Label tow valve positions clearly for future reference
  
• Keep a dedicated tow kit with wrenches, gloves, and valve instructions in the service truck
  
• Train operators on emergency towing procedures during onboarding
  

For fleet operations, consider installing quick-access tow valve covers or decals to reduce confusion during breakdowns.
Design Simplicity and Serviceability
The S250’s hydrostatic system is compact and efficient, but its sensitivity to forced movement requires careful handling. Bobcat designed the tow valves for field accessibility, and the loader’s frame includes reinforced tie-down points for secure transport. The machine’s diagnostic panel can help identify drive system faults before towing is attempted.
Operators appreciate the S250’s responsiveness and lifting power, but towing procedures must be respected to preserve drivetrain integrity.
Conclusion
Towing a Bobcat S250 requires more than just muscle—it demands mechanical awareness and procedural discipline. By properly opening the tow valves and securing the loader, operators can avoid costly damage and ensure safe relocation. In compact equipment, precision matters even when the engine is off. The S250 proves that smart handling starts with knowing how to move a machine when it can’t move itself.
