The Hough wheel loader is one of the pioneering machines in the field of construction and material handling equipment. Known for its versatility and strength, the Hough loader series laid the groundwork for modern wheel loaders that are now integral to many industries. This article takes a deep dive into the history, features, and evolution of Hough wheel loaders, with a focus on their design, performance, and legacy.
History and Evolution of Hough Wheel Loaders
Hough Manufacturing Company, founded in the early 1900s, was one of the earliest companies to produce wheeled loaders, starting with the Hough H-60 in the 1950s. These early models were designed to improve efficiency in loading and transporting materials in construction, mining, and agriculture. Prior to this innovation, most material handling was performed using bulldozers or other tracked equipment, which were not as fast or maneuverable.
By the 1960s, Hough loaders became a staple in the construction and mining sectors, with improvements made in lifting capacities, engine power, and hydraulic systems. The Hough H-70, introduced in the 1960s, was one of the key models, providing enhanced performance and efficiency in material handling.
In 1964, International Harvester acquired the Hough Company, further advancing the Hough loaders with more modern designs and innovations. By the 1970s, the Hough loaders were recognized as durable and reliable, often being used for years beyond their expected lifespan.
Design and Features of the Hough Wheel Loader
Hough wheel loaders were designed to operate in tough, demanding conditions, and their features reflected this need for reliability and efficiency. Some key design features included:
Hough loaders were designed with an emphasis on power and lifting capacity. Early models like the Hough H-60 and H-70 had capacities ranging from 1.5 to 3 cubic yards, which were significant for the time. The lifting capacity was crucial for moving bulk materials such as sand, gravel, and aggregate.
These machines were also known for their fast cycle times, especially when compared to tracked loaders. This made them ideal for operations that required quick turnaround times, such as in construction or quarrying.
Common Issues and Troubleshooting
Like any heavy machinery, Hough wheel loaders have their share of potential issues, especially as they age. Some common issues and troubleshooting tips include:
While Hough loaders are no longer in production, their legacy continues through the machines that followed. Today, International Harvester, which later merged with Case Corporation, eventually became part of CNH Industrial, a major player in the construction and agricultural equipment industry. The design principles and innovations developed by Hough continue to influence modern wheel loaders, particularly in terms of lifting capacity, operator comfort, and hydraulic systems.
The legacy of the Hough wheel loader is also evident in the continued popularity of machines like the Case 570N Tractor Loader and the CAT 966M, which carry forward many of the features pioneered by Hough, including ergonomic controls, increased hydraulic efficiency, and superior durability.
Comparing Hough with Other Early Wheel Loaders
In the early days of wheel loaders, companies like Hough faced competition from other manufacturers such as Clark Michigan, Caterpillar, and Allis-Chalmers. However, Hough's focus on versatility and durability gave it a strong reputation in various industries, including construction, mining, and agriculture. While other manufacturers also produced reliable machines, Hough's early adoption of hydraulic systems and advanced features helped it carve out a strong niche in the market.
Why Hough Wheel Loaders Are Still Relevant Today
Many older Hough wheel loaders are still in use today, particularly in regions where the cost of new equipment may be prohibitive. These machines continue to provide reliable service in material handling tasks, as their rugged design and strong build quality allow them to endure years of heavy use.
Moreover, the mechanical simplicity of older Hough machines makes them easier to repair compared to modern, electronically controlled wheel loaders. This ease of maintenance is a significant advantage, especially for operators working in remote areas or developing countries, where spare parts may be difficult to obtain.
Conclusion
The Hough wheel loader represents a significant milestone in the evolution of construction machinery. Its innovative design and emphasis on performance, durability, and versatility laid the foundation for modern wheel loaders. Though no longer in production, Hough loaders are still found in service today, a testament to the quality and reliability of their design.
The Hough series not only influenced the development of future wheel loaders but also played a critical role in shaping the future of construction equipment. Whether in the hands of collectors or still in daily use on job sites, the legacy of Hough’s engineering continues to be felt in the construction industry today.

Design and Features of the Hough Wheel Loader
Hough wheel loaders were designed to operate in tough, demanding conditions, and their features reflected this need for reliability and efficiency. Some key design features included:
- Hydraulic Lifting Systems
The Hough loaders were among the first to incorporate hydraulic lifting arms, significantly improving lifting capacity and precision. These systems allowed for better control and maneuverability, especially in situations requiring precise material handling.
- All-Wheel Drive
Many Hough models featured all-wheel drive (AWD) to enhance traction in rough terrain. This feature was crucial for improving stability when operating in environments like mines or construction sites with uneven surfaces.
- Durability
The rugged build of Hough wheel loaders was a key factor in their popularity. The use of high-strength steel and reinforced components made these machines capable of handling large loads and enduring harsh operating conditions.
- Operator Comfort and Control
While the technology in the early Hough loaders was relatively basic compared to modern standards, the company made early strides in improving operator comfort. For instance, the operators’ cab was designed to offer better visibility and control, enhancing productivity and safety.

Common Issues and Troubleshooting
Like any heavy machinery, Hough wheel loaders have their share of potential issues, especially as they age. Some common issues and troubleshooting tips include:
- Hydraulic Leaks
Hydraulic systems in older Hough loaders may experience leaks due to worn-out seals or damaged hoses. Regular inspections can help identify leaks early, which can be repaired by replacing seals or hydraulic hoses.
- Engine Wear and Tear
Older models, particularly those from the 1950s and 1960s, may face engine-related problems such as overheating or excessive exhaust smoke. These problems are often caused by improper maintenance, such as failure to replace filters or oil. Regular oil changes and cooling system maintenance are essential for preventing engine damage.
- Transmission Issues
The transmission in older Hough loaders may experience slipping or difficulty shifting due to worn-out clutch plates or low transmission fluid levels. It is important to inspect the fluid levels regularly and replace any worn-out parts to prevent further damage.
- Electrical Failures
Electrical issues, such as dead batteries or faulty alternators, are common in older loaders. Regular inspection of the battery, wiring, and alternator connections can help maintain the loader's electrical system.
- Tire Wear
Given the nature of wheel loaders, tire wear can become an issue, especially when used in rough terrains. Ensuring that the tires are properly inflated and regularly inspecting them for wear can extend their lifespan and maintain optimal performance.
