Evaluating the Dresser 175C Track Loader for Modern Utility Work
#1
The History Behind the Dresser 175C
The Dresser 175C track loader emerged during a transitional period in the heavy equipment industry. Originally developed under the International Harvester brand, the machine was later rebranded as Dresser following corporate restructuring in the 1980s. Dresser Industries, known for its oilfield and construction equipment, continued production of the 175C into the early 1990s before the line was absorbed into Komatsu’s portfolio. The 175C was designed to compete with Caterpillar’s 955L and similar mid-sized loaders, offering a balance of power, maneuverability, and affordability.
Though exact production numbers are difficult to verify, the 175C was widely distributed across North America and parts of Europe, particularly in forestry, land clearing, and agricultural sectors. Its reputation for mechanical simplicity and ruggedness has kept many units in operation decades after their release.
Core Specifications and Performance Profile
The Dresser 175C is powered by a DT-466 diesel engine, a 6-cylinder inline unit producing approximately 140–150 horsepower. Known for its reliability and ease of service, the DT-466 was also used in medium-duty trucks and school buses, making parts relatively accessible.
Key specifications include:
  • Operating weight: ~35,000 lbs (15,875 kg)
  • Bucket capacity: 2.5 to 3.0 cubic yards
  • Transmission: Powershift with torque converter
  • Undercarriage: Sealed and lubricated track system
  • Hydraulic system: Open center with gear-type pump
The machine features two-lever bucket controls, which many operators find more intuitive than the three-lever setups on comparable Caterpillar models. This configuration simplifies clamshell bucket operation and reduces operator fatigue during repetitive loading tasks.
Advantages in Field Operations
Operators who’ve spent time on both the Dresser 175C and the Caterpillar 955L often cite the 175C’s smoother grading performance and more responsive bucket control. The two-lever system allows for quicker clamping and dumping, especially when using a 4-in-1 bucket. In land clearing and truck loading scenarios, the Dresser’s hydraulic response and visibility from the cab offer a practical edge.
Additional benefits include:
  • Easier access to engine components for maintenance
  • Lower initial purchase cost compared to Caterpillar equivalents
  • Robust frame and loader arms suitable for forestry attachments
  • Compatibility with aftermarket parts due to shared engine lineage
One operator in Alabama used a 175C for clearing brush and grading trails across a 200-acre property. He noted that the machine’s balance and traction allowed him to work on slopes that would challenge wheeled loaders.
Known Limitations and Maintenance Challenges
Despite its strengths, the 175C has several drawbacks that prospective buyers should consider:
  • Visibility from the cab is slightly more restricted than on newer models
  • Parts availability can be inconsistent, especially for proprietary hydraulic components
  • Electrical systems may suffer from age-related corrosion and require rewiring
  • Undercarriage wear is common in older units, and track replacement can be costly
The sealed track system, while durable, requires regular inspection to prevent internal seal failure. Replacing track chains and rollers can exceed $10,000 depending on supplier and labor rates.
Additionally, the torque converter transmission, while smooth under load, may exhibit sluggish response if fluid levels drop or filters clog. Regular fluid changes and filter replacements are essential to maintain performance.
Comparing to the Caterpillar 955L
The Caterpillar 955L, produced during a similar timeframe, is often viewed as the benchmark in this class. It offers slightly better visibility and a more refined cab layout. However, the three-lever bucket control system can be cumbersome for operators unfamiliar with the setup.
In terms of resale value, Caterpillar machines tend to hold their price better due to brand recognition and dealer support. That said, the Dresser 175C can be a more economical choice for owner-operators who prioritize function over brand prestige.
Comparison highlights:
  • Dresser 175C: Better bucket control, lower cost, simpler maintenance
  • Caterpillar 955L: Superior visibility, stronger dealer network, higher resale
Recommendations for Buyers and Owners
For those considering a Dresser 175C, here are practical suggestions:
  • Inspect undercarriage components thoroughly before purchase
  • Verify engine compression and check for oil leaks around the valve cover
  • Test hydraulic response with a full bucket load
  • Confirm transmission shifts smoothly in all ranges
  • Source a parts manual and identify local suppliers for filters, seals, and hoses
If possible, find a unit with a 4-in-1 bucket and auxiliary hydraulics, which greatly expand the machine’s versatility. Adding LED work lights and a backup camera can also improve safety and usability.
Conclusion
The Dresser 175C remains a capable and cost-effective track loader for land clearing, grading, and general farm maintenance. While it may lack the polish of newer machines, its mechanical simplicity and responsive controls make it a favorite among operators who value hands-on reliability. With proper maintenance and a thoughtful approach to parts sourcing, the 175C can continue to serve as a dependable workhorse for years to come.
In a world increasingly dominated by electronics and emissions controls, the 175C stands as a reminder that sometimes, simpler is better—especially when the job is dirty, the terrain is rough, and the work never stops.
