Aveling Barford’s Engineering Legacy
Aveling Barford, a British manufacturer with roots dating back to the early 20th century, was known for producing robust road construction equipment, including motor graders, dump trucks, and rollers. Their graders—especially models like the MG5, PG6, and SGN2—were celebrated for their mechanical simplicity, rugged build, and unique 6x6x6 configuration: six wheels, six-wheel drive, and six-wheel steering. This setup offered exceptional traction and maneuverability, particularly in uneven or compacted terrain.
The company’s emphasis on mechanical drivetrains over hydraulic or electronic systems made their machines ideal for remote operations with limited access to advanced diagnostics or spare parts. Many units were powered by Leyland, Perkins, or Cummins engines, and featured powershift transmissions for smoother gear transitions under load.
Why the 6x6x6 Configuration Still Matters
In regions with hard, sunbaked soils—where ripping is often required before grading—the 6x6x6 drive system provides superior stability and pulling power. Unlike modern graders that rely on electronically controlled hydraulic front-wheel drive, Aveling Barford’s mechanical front drive can be repaired with basic tools. This is especially valuable in rural areas where mechatronic systems are difficult to service.
Operators in Africa and parts of Asia continue to favor these machines for their reliability and ease of maintenance. A broken shaft can be welded. A failed bearing can be replaced without proprietary tools. This philosophy aligns with the needs of small contractors working in harsh environments with limited budgets.
Challenges in Sourcing and Alternatives
Finding a working Aveling Barford grader today is difficult. The brand was never mass-produced at the scale of Caterpillar or John Deere, and many units have been retired or scrapped. Export logistics, parts availability, and condition uncertainty add layers of complexity.
For those seeking similar performance, alternatives include:
Mechanical vs. Electronic Drive Debate
Modern graders often use hydrostatic or electronically controlled front-wheel drive systems. While efficient when functioning, these systems can be costly to repair. In contrast, mechanical drives like those in Aveling Barford machines offer transparency and field-serviceability. For small operators without access to diagnostic tools or dealer networks, mechanical simplicity is not just a preference—it’s a necessity.
Budget Considerations and Practical Advice
For buyers with limited budgets (under $20,000), sourcing a fully operational 6x6x6 grader is unlikely. Machines in this range may require extensive refurbishment. Instead, consider:
The search for an Aveling Barford motor grader reflects a deeper desire for mechanical reliability, raw power, and field-serviceable design. While sourcing such a machine is challenging, understanding the core needs—traction, simplicity, and durability—can guide buyers toward practical alternatives. Whether it’s a Caterpillar 140G or a FIAT-Allis FG, the goal remains the same: a grader that works hard, lasts long, and doesn’t break the bank.

For those seeking similar performance, alternatives include:
- Caterpillar 140G: Widely regarded as one of the most reliable graders ever built. Parts are abundant, and many units include rear rippers.
- FIAT-Allis FG series: Known for durability and mechanical simplicity. Popular in Africa and Latin America.
- John Deere 770/772 models: Good dealer support and parts availability. Some older units feature mechanical front-wheel drive.
- Champion/Volvo graders: Often equipped with rear rippers and straightforward hydraulics.

- Prioritizing availability of spare parts and dealer support
- Choosing machines with rear rippers for productivity
- Avoiding units with complex electronics unless support is guaranteed
- Inspecting undercarriage, hydraulics, and transmission before purchase
