Introduction: The Hough Loaders - A Historical Overview
The Hough H60-D and Hough H65-D are part of a series of wheel loaders that were widely used in construction, mining, and material handling operations during the mid-20th century. Manufactured by the Hough Division of the Allis-Chalmers Corporation, these machines gained a reputation for their robust design and reliability, handling heavy-duty tasks with ease. Though they may be considered older models today, many of the features that made the H60-D and H65-D standout in their time are still relevant to heavy equipment operators and collectors.
Both the H60-D and H65-D were designed to tackle tough tasks like loading, lifting, and transporting materials in harsh environments. While the H60-D was generally more compact, the H65-D offered increased capacity and horsepower, making it suitable for larger-scale operations. In this article, we will explore their performance, common issues, and why these classic loaders continue to hold value in today’s market.
Key Features of the Hough H60-D and H65-D Loaders
Like any older machinery, both the Hough H60-D and H65-D are not without their common issues. These machines were designed to be highly durable, but wear and tear over the years can lead to certain recurring problems that operators need to be aware of.
Maintaining these classic Hough loaders is essential for maximizing their operational life. Here are some key maintenance tips to keep these machines running efficiently:
The Hough H60-D and Hough H65-D loaders may no longer be the latest models on the market, but they remain an important part of heavy equipment history. Their durability, powerful engines, and reliability made them valuable assets to those who used them for material handling, construction, and mining tasks. Although they come with some common issues due to their age, with proper maintenance and care, these classic machines can still deliver impressive performance.
For those who own or collect vintage heavy equipment, the Hough 60-D and 65-D are timeless pieces of engineering that continue to hold value. With regular maintenance and attention to their common issues, these loaders will remain useful tools for years to come, proving that sometimes, the old machines still have a lot to offer.

Key Features of the Hough H60-D and H65-D Loaders
- Powerful Engine Performance
Both the Hough H60-D and H65-D were powered by diesel engines, which provided a strong and reliable source of power for heavy lifting and digging tasks. The H60-D was equipped with a 6-cylinder engine that offered good power-to-weight ratio for its size. Meanwhile, the H65-D had a more powerful engine, typically with higher horsepower for increased capacity and performance. This made the H65-D a go-to choice for larger material handling tasks and operations where more power was required.
Real-World Example: One operator mentioned that their H65-D, which was used in a mining operation, could easily lift large piles of rock and gravel with its increased horsepower. This engine power allowed them to work quickly and efficiently, often outperforming smaller loaders in terms of productivity.
- Hydraulic System for Smooth Operation
Both loaders featured a hydraulic lifting system that allowed the bucket to lift and tilt with ease. The H65-D had a more advanced hydraulic system, improving lifting capabilities for heavier materials. Operators could control the bucket precisely, even under heavy load conditions, making these machines ideal for material handling and earthmoving.
Real-World Example: In a construction site setting, one operator reported how the hydraulic system in the Hough H65-D made material handling tasks far easier, reducing manual labor and making loading quicker. The responsive hydraulic controls also improved safety, as the machine could be easily maneuvered in tight spaces.
- Durable Tires and Frame
The H60-D and H65-D were both equipped with heavy-duty tires and strong frames designed to withstand tough terrain and rough working conditions. The reinforced steel construction and robust axle systems allowed these machines to handle large volumes of material without significant wear and tear, even under harsh conditions.
Real-World Example: A construction company using both models in a variety of operations shared how the machines often outlasted newer machines, with the tires and frames proving to be exceptionally durable. Despite the wear and tear from rough terrain, the H60-D and H65-D continued to operate effectively for many years.
- Operator Comfort and Visibility
Although the Hough loaders were designed for tough, industrial use, they still incorporated elements of comfort for operators. The cabs were designed with a relatively spacious area for the operator, offering good visibility of the work area. While not as advanced as modern cabs with climate control and ergonomic seating, the cabins in both models were functional, offering operators a relatively comfortable working environment.
Real-World Example: One operator mentioned that, although the controls of the H60-D were a bit stiff compared to modern machines, the clear visibility and simple, effective design of the cab made long shifts more manageable.
Like any older machinery, both the Hough H60-D and H65-D are not without their common issues. These machines were designed to be highly durable, but wear and tear over the years can lead to certain recurring problems that operators need to be aware of.
- Hydraulic System Leaks and Failures
Over time, hydraulic systems can develop leaks or suffer from failures due to old seals, worn hoses, or other internal issues. A hydraulic leak can reduce the lifting power and performance of the loader, making it less efficient.
Potential Causes:- Worn-out hydraulic seals or hoses
- Hydraulic fluid contamination
- Clogged filters or faulty pumps
- Worn-out hydraulic seals or hoses
- Engine and Fuel System Issues
Another common issue with older loaders like the H60-D and H65-D is engine-related problems. These problems may include poor starting, rough idling, or loss of power, which are often related to the fuel system or engine wear.
Potential Causes:- Clogged fuel filters
- Dirty air filters
- Worn-out engine components like fuel injectors or injectors
- Clogged fuel filters
- Transmission Problems
The transmission system of the Hough loaders can also wear out over time, especially in machines that have been used heavily. Common issues include slipping gears or difficulty shifting between gears, which can make the loader harder to operate and reduce its overall performance.
Potential Causes:- Low transmission fluid levels
- Worn-out transmission components
- Leaking seals or damaged gears
- Low transmission fluid levels
Maintaining these classic Hough loaders is essential for maximizing their operational life. Here are some key maintenance tips to keep these machines running efficiently:
- Regular Fluid Changes
Changing the engine oil, hydraulic fluid, and transmission fluid regularly is essential to ensure smooth performance. Using the right grade of oil and fluid, as recommended by the manufacturer, is critical for maintaining the health of the engine and hydraulic systems.
- Inspection of Key Components
Conduct thorough inspections of the hydraulic system, engine components, tires, and transmission. Regularly check for leaks, cracks, or signs of wear, especially in components that are subject to heavy use.
- Cleaning and Maintenance of Filters
Keeping air and fuel filters clean is essential for smooth engine performance. Clogged filters can cause the engine to run inefficiently or even stall, so it’s important to replace them regularly.
- Tire and Frame Checks
Given the heavy-duty nature of the work these loaders perform, it is important to inspect tires for wear and tear. Regularly check the frames and axles for cracks or damage to ensure the loader remains stable and can handle heavy loads.
The Hough H60-D and Hough H65-D loaders may no longer be the latest models on the market, but they remain an important part of heavy equipment history. Their durability, powerful engines, and reliability made them valuable assets to those who used them for material handling, construction, and mining tasks. Although they come with some common issues due to their age, with proper maintenance and care, these classic machines can still deliver impressive performance.
