Identifying the 19 Huber Motor Grader: A Historical Insight and Technical Overview

[MikePhua]

Motor graders are crucial machines in construction, road maintenance, and other earth-moving projects. They are used for leveling and grading surfaces, creating a flat, smooth surface. Among the many motor grader manufacturers, Huber is a name that stands out, especially for its historical contribution to the machinery industry. The Huber 19 motor grader, an older model, has become a point of curiosity and intrigue for enthusiasts, collectors, and those with an interest in vintage equipment. In this article, we’ll explore the Huber 19 motor grader, its features, how to identify it, and its place in the world of heavy machinery.
History of Huber Machinery
The Huber Manufacturing Company, founded in 1909, was an American manufacturer known for producing a variety of industrial machines, including motor graders, road rollers, and other road-building equipment. Over the years, Huber gained a reputation for quality and innovation, particularly in the motor grader market. The Huber 19 was one of the models produced during the early to mid-20th century and remains a point of interest for collectors and restoration enthusiasts.
In the 1920s and 1930s, the motor grader market was still developing, and manufacturers like Huber helped shape the industry. While the Huber company eventually ceased operations in the 1960s, the legacy of its equipment lives on through the machines that are still in use or restoration projects.
Key Features of the Huber 19 Motor Grader
The Huber 19 motor grader was designed to be a versatile machine, capable of handling a range of tasks from road maintenance to grading and other construction projects. Some of its standout features include:

1. Engine Specifications – The Huber 19 was powered by a gasoline or diesel engine (depending on the specific model and modification), which provided sufficient power for the heavy lifting and grading operations it was intended for. The engine’s horsepower ranged from 50 to 60 horsepower, which was quite powerful for its time.
   
2. Transmission – The grader was typically equipped with a manual transmission system, which allowed for more control over the vehicle’s speed and torque. It often featured a gear-driven system with a basic four-speed transmission.
   
3. Blade Control – As with modern motor graders, the blade control system on the Huber 19 allowed operators to adjust the blade height, tilt, and angle to achieve the desired grading results. It was manually operated, with mechanical linkages to control the blade's movement.
   
4. Mechanical Components – Many of the components on the Huber 19 were mechanical, reflecting the technology of its time. For example, the steering mechanism was typically a mechanical link, and hydraulic systems were not as advanced as those seen on more modern machines.
   
5. Chassis and Design – The Huber 19 had a relatively simple, rugged design. It featured a steel chassis, with the motor and blade assembly positioned for optimal balance. The front and rear axles were also heavy-duty, built to handle the stress of grading and rough terrain.
   

Identifying a Huber 19 Motor Grader
Identifying a Huber 19 motor grader can be a challenge due to the age of the equipment and the lack of easily accessible records. However, there are a few key characteristics that can help you identify this machine:

1. Serial Number Plate – Like many other pieces of equipment, the Huber 19 would have a serial number plate affixed to the machine. This plate often contains valuable information, such as the model number, engine specifications, and manufacturing year. You can usually find the plate near the engine compartment or on the chassis.
   
2. Chassis Design – The general appearance of the Huber 19 is distinct with a relatively simple chassis design. The front axle is typically set farther apart than modern motor graders, and the machine’s overall proportions are more compact compared to later models. It’s important to note the distinct, angular frame that is characteristic of many older Huber graders.
   
3. Blade Mechanism – The blade system on the Huber 19 was typically manually operated, so it may not have the complex hydraulic systems that modern graders are known for. If you see a grader with a mechanical linkage for blade adjustment, it could very well be a Huber model.
   
4. Wheel Arrangement – The Huber 19 motor grader had a standard wheel arrangement, often with a set of large rear wheels and smaller front wheels, which is a common feature in vintage motor graders.
   
5. Engine Type – The engine powering the Huber 19 would typically be a gasoline or early-model diesel engine, which might be an indicator when identifying the machine. If the engine is a vintage model or has a classic carburetor system, it could be a strong sign that the machine is from the Huber brand.
   
6. Other Identifying Markings – Sometimes, older equipment will have the Huber logo or other branding marks engraved on the machine’s frame or body. These could be clues when determining if the grader is a Huber 19.
   

Common Issues with the Huber 19 Motor Grader
As with any vintage machinery, the Huber 19 motor grader may present a few challenges, particularly due to age and wear. Common issues include:

1. Engine Problems – Like many old engines, those in the Huber 19 may have been subject to excessive wear or lack of proper maintenance. Engine rebuilds may be necessary for older machines.
   
2. Mechanical Linkage Failure – The manual blade and steering systems can become worn or seized over time. The mechanical components might require frequent maintenance or replacement.
   
3. Rust and Corrosion – Given the age of the Huber 19, rust and corrosion are common issues, especially in parts that were exposed to the elements.
   
4. Hydraulic System Issues – Although the Huber 19 doesn’t feature a fully hydraulic blade system, if any upgrades were done over the years, those hydraulic systems may suffer from leaks or lack of pressure.
   

Restoration and Maintenance of the Huber 19
Restoring a vintage machine like the Huber 19 requires time, effort, and a knowledge of its original components. Here are a few restoration and maintenance tips for keeping the Huber 19 in working condition:

1. Find Original Parts – Restoring a Huber 19 requires finding authentic parts, which can be difficult due to the age of the machine. However, many parts can be sourced from specialized vintage machinery dealers or even custom-manufactured by skilled fabricators.
   
2. Engine Overhaul – The engine may need a full overhaul, including piston replacements, gaskets, and carburetor adjustments. Regular engine maintenance and oil changes are crucial to maintaining performance.
   
3. Clean and Lubricate – All moving parts, including the blade control mechanism and steering linkage, should be cleaned and lubricated regularly to prevent rust and ensure smooth operation.
   
4. Rust Treatment – If the machine has significant rust, it is essential to remove it thoroughly and treat the surface with anti-corrosion agents or coatings to prevent further damage.
   
5. Upgrade if Necessary – Some enthusiasts choose to upgrade certain systems (like the engine or blade control) for better performance while keeping the original look and feel of the grader.
   

Conclusion
The Huber 19 motor grader is an iconic piece of machinery, showcasing the evolution of construction and earth-moving equipment in the early 20th century. While identifying this vintage grader can be challenging, understanding its key features, historical context, and restoration processes can make the task more manageable. Whether you're looking to restore one of these machines or simply want to learn more about its role in the heavy equipment industry, the Huber 19 continues to hold a special place in the hearts of machinery enthusiasts and collectors.
