Introduction to a Hidden Workhorse
Among seasoned equipment operators and collectors, certain machines are affectionately known as “hidden gems”—tools that quietly outperformed their contemporaries without ever becoming household names. One such machine is the Michigan 175B wheel loader, a heavy-duty, mid-20th-century powerhouse that earned its reputation through raw strength, simplicity, and dependability. Built before the era of electronic controls and plastic panels, the 175B represents the iron-and-oil era of heavy machinery.
Design Philosophy and Build Quality
The Michigan 175B was produced by Clark Equipment Company, which later became part of the VME Group and eventually evolved into Volvo Construction Equipment. The 175B was a heavy-duty loader in the 30,000–40,000 lb class, boasting mechanical drive, a robust steel frame, and powerful hydraulics. Key features included:
Performance Characteristics
While not as fast or refined as modern loaders, the 175B delivered in the areas that mattered:
The Appeal of “Old Iron”
What draws people to machines like the Michigan 175B decades after their prime?
Real-World Stories and Use Cases
One operator in northern Minnesota used his 175B for over 20 years in a gravel pit. Despite freezing winters and hard rock digging, the loader never failed to start—often running alongside much newer machines that suffered repeated electronic issues.
Another example comes from a scrapyard in Appalachia, where a 175B—paint faded and seat cracked—continued feeding shears and balers day after day. The owner claimed it cost less to maintain the 175B for five years than a single repair on a new Tier 4 loader.
A small group of collectors in the Midwest even restored a 175B to like-new condition, sourcing NOS (new old stock) decals and repainting it in its original industrial yellow. The machine now runs in parades and vintage equipment shows, a rolling tribute to American manufacturing.
Challenges and Limitations
Of course, the Michigan 175B is not without its drawbacks:
Terminology Explained
While the Michigan nameplate has faded into construction history, its machines continue to dig, lift, and move earth across North America. The 175B, in particular, stands as a testament to a time when brute strength and simplicity were the hallmarks of good engineering.
In a world of emissions modules, sensor arrays, and diagnostics ports, the Michigan 175B reminds us that there is still a place for levers, steel, and iron grit. As more enthusiasts rediscover these forgotten giants, they ensure the memory—and utility—of machines like the 175B will live on for decades to come.

The 175B was a heavy-duty loader in the 30,000–40,000 lb class, boasting mechanical drive, a robust steel frame, and powerful hydraulics. Key features included:
- Articulated steering, allowing tight turns in confined spaces
- Massive planetary axles, ideal for hard dig applications
- Basic but durable cab design, with analog gauges and manual levers
- Frame-mounted counterweight, enhancing lift capacity
- Straightforward mechanical systems, with little to no electronics
Performance Characteristics
While not as fast or refined as modern loaders, the 175B delivered in the areas that mattered:
- Excellent breakout force, due to its rigid boom geometry and hydraulic setup
- High lift capacity, making it suitable for rock, timber, and scrap work
- Simplicity in operation, with intuitive controls and easy access for repairs
- Durability, with many machines operating for decades under severe conditions
The Appeal of “Old Iron”
What draws people to machines like the Michigan 175B decades after their prime?
- Low cost of ownership: Compared to newer machines, parts are cheaper and the lack of electronics reduces diagnostic complexity.
- Ease of repair: Mechanics with basic tools and mechanical knowledge can keep these loaders running without laptops or dealer service calls.
- Sheer toughness: Built with thick plate steel and overbuilt components, these machines tolerate abuse that would cripple newer, lighter machines.
- Character: The throaty growl of a Detroit Diesel and the feel of solid levers create a visceral operating experience absent in digital cabs.

Challenges and Limitations
Of course, the Michigan 175B is not without its drawbacks:
- Parts availability: While common wear items like seals and filters are easy to find, specialty parts such as axles or transmission internals may require salvage or fabrication.
- Fuel consumption: Detroit Diesels are notoriously thirsty, particularly under load.
- Noise and comfort: The open cab and engine scream make for a rough ride by modern standards.
- Manual effort: Unlike modern pilot-controlled machines, the 175B requires some physical muscle to operate over long shifts.
Terminology Explained
- Breakout Force: The amount of force a loader can exert at the bucket edge to break into a pile or material.
- Powershift Transmission: A transmission that allows shifting gears under load without a clutch.
- Planetary Axles: Axles with internal reduction gearing, increasing torque and durability.
- NOS (New Old Stock): Unused parts manufactured during the original production era, often sought for restorations.
