Introduction to Hough Loaders
Hough loaders, specifically the Hough H65C, H70C, and other similar models, are among the classic equipment used in the construction, mining, and material handling industries. Founded in the early 20th century, the Hough brand has become synonymous with the evolution of wheel loaders, thanks to its innovative design and engineering.
Originally designed and manufactured by the Hough Manufacturing Company in the mid-20th century, these loaders were designed to provide high-efficiency performance in a compact, powerful form factor. Over the decades, Hough loaders have developed a reputation for durability and ease of maintenance, making them popular for a variety of tasks, including roadwork, digging, and moving materials.
Today, Hough loaders, such as the H65C and H70C models, are still in use and sought after in certain segments of the equipment market, even though the Hough brand itself has been absorbed by other companies over time.

The Evolution of Hough Loaders
The Hough Manufacturing Company was established in the early 1900s, specializing in the production of heavy equipment. Their flagship product, the Hough Loader, revolutionized the material handling industry by introducing wheeled loaders with greater lifting capacities and maneuverability.
By the 1950s and 1960s, Hough had produced a variety of models to address different needs in the industry. One of their most notable innovations during this period was the Hough H65C, which set new standards for performance and reliability in wheel loaders. It was engineered for construction, road-building, and general material-moving tasks, providing a highly efficient solution for operators.
Throughout the 1970s and 1980s, the company continued to improve its loader designs, introducing models like the H70C with more powerful engines, better hydraulics, and improved lifting capacities. These loaders became staples in the field and remained competitive for decades.
Today, while the Hough brand is no longer independently operating, its legacy lives on. It is now a part of companies like Case and later, Caterpillar, who have integrated Hough's engineering into their own designs.

Popular Hough Loader Models
Hough loaders come in a range of sizes, with different models designed for specific applications. The most well-known models include the H65C and H70C, each of which has unique features suited to various tasks.

1. Hough H65C
   • Engine and Power: The H65C was powered by a robust diesel engine, providing ample horsepower for heavy-duty tasks. It was designed to lift significant loads, making it ideal for material handling, construction, and general lifting.
     
   • Hydraulic System: The hydraulic system on the H65C was engineered for precision and power. This allowed operators to use the loader for digging, lifting, and material loading tasks with greater efficiency and control.
     
   • Design Features: With its compact size and sturdy frame, the H65C was known for its maneuverability, which made it effective in tight spaces and busy work sites. Its front bucket was designed for maximum capacity, enabling it to carry and move large amounts of material.
     
2. Hough H70C
   • Engine and Performance: The H70C featured an upgraded engine compared to the H65C, offering more horsepower for demanding tasks. The larger engine size enabled it to handle larger loads and more difficult terrains.
     
   • Lifting Capacity: One of the key improvements in the H70C over earlier models was its increased lifting capacity. This made the H70C more effective in larger construction projects, where heavy lifting and hauling were essential.
     
   • Hydraulics and Control: The hydraulic system in the H70C was enhanced for more efficient power delivery, allowing smoother operation of the bucket and other attachments. Its enhanced control system helped reduce operator fatigue during long working hours.
     

Common Problems with Hough Loaders
While Hough loaders are generally considered reliable, older models like the H65C and H70C can develop issues due to their age and wear. These are some common problems reported by operators:

1. Hydraulic Leaks: Due to the heavy use of hydraulic systems, older Hough loaders can develop leaks in their hydraulic lines or cylinders. This may lead to a decrease in hydraulic pressure, reducing lifting capacity and operational efficiency.
   • Solution: Regular inspection of hydraulic lines and seals is essential. Replacing worn hoses and seals before they leak can save time and repair costs.
     
2. Engine Problems: Older engines in Hough loaders can suffer from issues such as reduced power, overheating, or poor fuel efficiency. These problems can be caused by worn components, clogged filters, or old fuel systems.
   • Solution: Regular engine maintenance, including oil changes, fuel filter replacements, and cooling system checks, can help prevent engine failures. Additionally, upgrading to a more modern engine may be considered in extreme cases.
     
3. Transmission Issues: The transmission in older Hough loaders can begin to wear out, causing slipping, difficulty shifting, or complete transmission failure.
   • Solution: Proper maintenance and fluid checks can help prevent transmission problems. In cases of severe damage, transmission repairs or replacements may be necessary.
     
4. Electrical System Failures: As with many older machines, electrical system failures can occur, particularly in the wiring or connections to the display panel and other controls.
   • Solution: Regularly check wiring and electrical connections for wear or corrosion. Ensure that the battery is in good condition and properly charged.
     

Maintaining Your Hough Loader
Maintenance is essential for ensuring that a Hough loader continues to operate at peak performance. Regular checks of hydraulic systems, engine components, and the electrical system can prevent unexpected breakdowns.

1. Hydraulic System: Inspect and replace hydraulic fluid regularly. Ensure that hoses and connections are tight and free from leaks. Pay attention to any changes in hydraulic performance, such as slower bucket movements or difficulty lifting heavy loads, which could indicate problems.
   
2. Engine Care: Regularly change the oil, inspect the air filter, and keep the engine cool. This not only extends the life of the engine but also ensures it operates efficiently, reducing fuel consumption and emissions.
   
3. Transmission and Drivetrain: Regularly check the transmission fluid and replace it when necessary. Ensure that the drivetrain components, such as the drive shafts and axles, are properly lubricated and functioning well.
   
4. Electrical System: Check the battery and all electrical connections to prevent starting problems. Ensure that fuses are in good condition and that wiring is free of corrosion.
   

Conclusion
The Hough loader series, including the H65C and H70C models, represent a pivotal moment in the history of construction machinery. While the brand is no longer independent, its legacy continues through its influence on modern equipment design. Hough loaders remain popular for their durability, simple mechanics, and adaptability to various tasks.
Despite their age, Hough loaders can still provide valuable service when maintained properly. Operators should be aware of common issues, such as hydraulic leaks, engine problems, and transmission wear, but with regular upkeep and the right repairs, a Hough loader can continue to deliver excellent performance for many years. Whether it's the H65C or H70C, these machines have proven themselves as reliable workhorses on the job site.
