The MF200 Crawler and Its Mechanical Legacy
The Massey Ferguson MF200 crawler was introduced in the 1960s as a compact, rugged tracked tractor designed for light construction, land clearing, and agricultural tasks. Built during a time when mechanical simplicity was prized, the MF200 featured a dry steering clutch system and mechanical final drives. Massey Ferguson, a company with roots tracing back to the 19th century, was known for its durable agricultural and industrial equipment. The MF200 was never mass-produced in the same volumes as its wheeled counterparts, but it earned a reputation for reliability in tough terrain.
Understanding the Steering Clutch System
The MF200 uses a pair of dry steering clutches—one for each track—to allow the operator to disengage power to either side and steer the machine. These clutches are housed within the final drive compartments and are actuated via mechanical linkages. Over time, especially in machines that sit idle for extended periods, these clutches can seize due to:
Initial Remedies and Penetrating Fluid Techniques
One of the first steps in attempting to free a stuck clutch is to apply penetrating fluids such as WD-40, diesel fuel, or ATF-acetone mix into the clutch housing. The challenge lies in locating the correct inspection or access port—often a small plug or plate on the side of the final drive housing. Once located, the fluid can be sprayed or poured in, ideally while rocking the machine or applying gentle pressure to the steering lever to encourage movement.
This method is not guaranteed but has been successful in cases where the clutch is only lightly seized. It may take several days of soaking and repeated attempts to see results.
Mechanical Intervention and Disassembly
If penetrating fluids fail, the next step involves mechanical disassembly. This is labor-intensive and requires:
Preventive Measures for Long-Term Reliability
To prevent future clutch seizure:
A landowner in Ontario inherited an MF200 that had sat idle for over a decade. When attempting to move it, he found the left steering clutch completely frozen. After several days of soaking with diesel and rocking the machine with a pry bar, the clutch finally broke free. He later installed a small inspection plug to allow future lubrication without disassembly—a simple modification that saved him hours of labor.
Conclusion
Stuck steering clutches in the MF200 crawler are a predictable outcome of age, moisture, and inactivity. While penetrating fluids may offer a low-effort solution, full mechanical disassembly is often required for long-term reliability. With proper care and occasional use, even a vintage crawler like the MF200 can continue to serve for decades, a testament to the enduring legacy of Massey Ferguson engineering.

These clutches are housed within the final drive compartments and are actuated via mechanical linkages. Over time, especially in machines that sit idle for extended periods, these clutches can seize due to:
- Corrosion from moisture ingress
- Friction disc adhesion caused by rust or oil contamination
- Lack of use, which allows the clutch plates to bond together
- Deteriorated seals, leading to oil leakage and contamination

Mechanical Intervention and Disassembly
If penetrating fluids fail, the next step involves mechanical disassembly. This is labor-intensive and requires:
- Removing the track and final drive cover
- Extracting the clutch pack
- Cleaning or replacing the friction discs and pressure plates
- Inspecting the throwout bearing and linkage for wear
Preventive Measures for Long-Term Reliability
To prevent future clutch seizure:
- Operate the machine regularly, even if only for short periods
- Store the crawler under cover or use tarps to reduce moisture exposure
- Apply rust inhibitors or fogging oil into the clutch housing during long-term storage
- Ensure all seals are intact to prevent water ingress
