Running and Maintaining the Massey Ferguson 600C Dozer

The Massey Ferguson 600C and Its Hanomag Origins
The Massey Ferguson 600C dozer is a product of a unique cross-continental collaboration. Originally designed and built by Hanomag in Germany, the machine was later rebranded under Massey Ferguson following their acquisition of Hanomag’s construction division in 1974. The 600C represents a transitional phase in European-American equipment manufacturing, blending German engineering with North American branding. Though Massey Ferguson eventually exited the construction equipment market, the 600C remains a rare but capable machine in the field.
Standard configurations included a Hanomag D962K six-cylinder diesel engine rated at 144 net horsepower, a full powershift transmission (MF-Hanomag G.523), and optional ripper or winch attachments. Operating weight ranged from 31,100 to 35,050 pounds depending on blade type and undercarriage configuration. Buyers could choose between standard, long-track, or low ground pressure (LGP) versions, with either straight or angle blades.
Terminology Clarification

• Powershift Transmission: A hydraulic transmission allowing gear changes without clutching, ideal for dozing under load.
  
• Torque Converter: A fluid coupling that multiplies engine torque, especially useful during acceleration or pushing.
  
• LGP Undercarriage: Tracks designed for soft terrain, distributing weight over a larger surface area.
  
• Tilt Blade: A blade that can angle left or right, improving grading precision.
  
• Steering Clutch: A mechanism that disengages one track to allow turning.
  

Operational Controls and Layout
The 600C’s control layout reflects its era—mechanical, intuitive, and built for durability. On the left side of the operator’s seat, three levers typically control throttle, gear selection (high, medium, low), and a safety lockout. On the right, two levers manage blade lift and tilt, and auxiliary hydraulics if equipped.
The floor pedals include:

• Left and right steering clutches with integrated brakes
  
• Center pedal for emergency braking or track lock
  
• Optional decelerator pedal depending on configuration
  

Shifting between forward and reverse is typically done via the gear selector lever, with directional changes requiring throttle modulation to avoid drivetrain shock. Operators are advised to avoid using third gear in reverse due to accelerated undercarriage wear.
Performance and Practical Use
Despite its age, the 600C remains a viable machine for small-scale earthmoving, land clearing, and farm use. Its torque converter and powershift transmission allow smooth operation under load, and the tilt blade adds versatility for slope work and finish grading.
However, the machine’s age and limited parts availability pose challenges. With over 8,000 hours on many surviving units, wear in the undercarriage, hydraulic seals, and electrical systems is common. Owners often resort to creative solutions, such as retrofitting more common undercarriage components or swapping engines. One notable example involved a Mack truck engine being installed in a loader variant of the same platform.
Parts Availability and Historical Context
The 600C’s lineage is complicated. After Massey Ferguson sold Hanomag to the IBH Group in 1980, the company collapsed in 1984 due to financial fraud. Hanomag limped along until Komatsu acquired it in 1989, eventually discontinuing the original Hanomag equipment lines in favor of manufacturing Komatsu machines for the European market.
As a result, parts for the 600C are scarce. Some components may be sourced from salvage yards, while others require custom fabrication. Manuals can occasionally be found online or ordered through AGCO, which inherited Massey Ferguson’s agricultural legacy.
Maintenance Recommendations
To keep a 600C running:

• Change engine oil every 100 hours
  
• Replace hydraulic filters every 500 hours
  
• Inspect track tension monthly
  
• Grease blade pivots and steering clutches weekly
  
• Monitor transmission fluid for contamination
  

Operators should throttle down briefly before shifting directions to reduce drivetrain stress. Avoid high-speed reverse operation and inspect blade tilt cylinders for leakage or drift.
Cost and Value Considerations
Purchasing a 600C today is a gamble. Machines may sell for under $7,000 at auction, but repairs can quickly exceed that if major components fail. However, for light-duty use—such as grading driveways, clearing brush, or building ponds—the machine can deliver excellent value. Even 20 hours of productive use may justify the purchase price when compared to rental rates.
In 2024, a Missouri farmer acquired a 600C for $6,400 sight unseen. Despite lacking experience with dozers, he found the machine started easily and performed basic tasks. With scrap value estimated at $3,000, even limited use could yield a favorable cost-per-hour ratio.
Conclusion
The Massey Ferguson 600C dozer is a relic of a complex industrial history, yet it still holds practical value for owners willing to learn its quirks and maintain it with care. While parts are scarce and documentation limited, the machine’s robust design and straightforward controls make it a rewarding project for mechanically inclined operators. Whether clearing land or grading a farm road, the 600C proves that even discontinued iron can still move dirt with authority.
