The Hough 60D wheel loader represents a remarkable chapter in the evolution of heavy equipment. Built during a time when mechanical simplicity, raw steel, and operator skill defined the industry, the 60D became a dependable workhorse for construction, mining, agriculture, and municipal operations.
This article provides a detailed, narrative‑style exploration of the Hough 60D—its development history, mechanical characteristics, strengths, weaknesses, and real‑world stories—creating a complete standalone reference for anyone interested in this classic loader.
Company Background and Historical Context
The Hough brand traces its roots to Frank G. Hough Company, founded in the early 20th century and widely recognized as a pioneer in wheel loader development. Hough introduced some of the earliest articulated loaders and became known for rugged, reliable machines that could withstand harsh environments.
In the 1950s and 1960s, International Harvester (IH) acquired Hough, integrating its engineering expertise into IH’s expanding construction equipment division. Under IH, the Hough name continued to appear on wheel loaders, including the 60D, which benefited from:
Development History of the Hough 60 Series
The Hough 60 series evolved through several iterations:
Technical Characteristics
The Hough 60D typically features:
Engine
A transmission that allows gear changes under load using hydraulic clutch packs, improving productivity and reducing operator fatigue.
Strengths of the Hough 60D
The 60D earned its reputation through several key advantages:
Durability
Thick steel, simple mechanics, and robust components allow the machine to survive decades of use.
Ease of Maintenance
Most repairs can be performed with basic tools, making it ideal for small shops and owner‑operators.
Strong Hydraulics
The loader arms and bucket deliver impressive breakout force for a machine of its era.
Good Visibility
The operator station provides clear sightlines to the bucket and work area.
Affordability
Used units remain inexpensive compared to modern loaders.
Common Issues and Their Causes
As with any older machine, the 60D has recurring issues due to age and heavy use.
Hydraulic Leaks
The maximum force the loader can exert to lift or pry material from a pile.
Diagnostic Approach
A structured diagnostic method helps identify issues efficiently.
1. Inspect Hydraulic System
Check fluid level, filter condition, and cylinder seals.
2. Test Transmission Pressure
Low pressure indicates internal wear.
3. Evaluate Engine Performance
Check compression, fuel delivery, and exhaust smoke.
4. Inspect Steering Components
Look for loose joints and worn bushings.
5. Check Electrical System
Verify charging voltage and inspect grounds.
Real‑World Case Studies
Case 1: A 60D used in a gravel pit
A contractor used a 60D for loading trucks. After years of service, the loader developed weak lift power. The cause was a worn hydraulic pump. Replacing the pump restored full performance.
Case 2: Transmission slipping under load
A municipality’s 60D struggled to push into piles. Pressure testing revealed worn clutch packs. A rebuild solved the issue.
Case 3: Hard starting in cold weather
A farmer found the machine difficult to start in winter. Installing a block heater and switching to winter‑grade diesel improved reliability.
Case 4: Steering play after decades of use
A land‑clearing operator noticed excessive steering looseness. Replacing worn tie rods and rebuilding the steering cylinder restored precise control.
Maintenance Recommendations
To keep the 60D reliable:
Anecdotes and Industry Stories
A veteran operator once said, “A Hough loader may not be fancy, but it will outlive the job.”
Another story involved a 60D used on a farm for over 30 years. The machine loaded manure, cleared snow, moved gravel, and even lifted hay bales—proving its versatility.
A small contractor shared that the 60D was the only loader that could be repaired in the field with basic tools, making it invaluable during remote projects.
Why the Hough 60D Remains Popular Today
Even decades after production ended, the 60D remains popular because:
Conclusion
The Hough 60D wheel loader is a durable, practical, and operator‑friendly machine that has earned its place as a classic in the heavy equipment world. Its strong hydraulics, simple mechanical systems, and long‑term reliability make it suitable for a wide range of tasks—from loading gravel and clearing snow to farm chores and industrial work.
While age‑related issues such as hydraulic leaks, transmission wear, and electrical faults are common, these problems are manageable with proper maintenance and systematic troubleshooting.
For owners, operators, and enthusiasts, the 60D remains a respected and capable machine—proof that well‑built equipment can remain productive for generations.
