Introduction
The IH (International Harvester) 3820 Series A is a notable piece of agricultural machinery, primarily designed to enhance productivity on the farm. As part of the broader line of tractors and heavy equipment produced by International Harvester, the 3820 Series A has found its place in the hearts of farmers and heavy equipment enthusiasts due to its performance, reliability, and versatility. In this article, we will explore the history, features, maintenance tips, and troubleshooting for the IH 3820 Series A, while also considering its place in the broader context of farming equipment evolution.
Historical Background of International Harvester
International Harvester (IH), founded in 1902, was a major American manufacturer of agricultural machinery, trucks, and other heavy equipment. The company became one of the largest and most influential manufacturers in the world, supplying farms across the United States and globally. IH’s success was attributed to its continuous innovation and commitment to providing powerful machinery to aid in agricultural productivity.
In the 1980s, IH began to face increased competition and eventually sold its agricultural division to Case Corporation, which later became Case IH, a leading brand in modern agricultural machinery. Despite this, the legacy of International Harvester continues, with tractors like the IH 3820 Series A standing as examples of the company's engineering excellence.
IH 3820 Series A: Key Features and Specifications
The IH 3820 Series A was designed as a robust utility tractor that could handle a wide variety of tasks on the farm. It was equipped with a powerful engine, versatile transmission, and capable hydraulics, making it ideal for tasks such as tilling, planting, and pulling various types of farm equipment. The primary features of the 3820 Series A include:

• Engine and Powertrain
  The IH 3820 Series A comes equipped with a 3.6L, four-cylinder engine. With an engine output of around 50 horsepower, it provided the ideal balance of power and fuel efficiency for small to medium-sized farms. This engine allows the 3820 to perform a range of tasks without being too large or unwieldy for smaller operations.
  
• Transmission
  The tractor features a fully synchronized gear transmission system, which enables smoother gear shifts during operation. This system was particularly advantageous for farming tasks that required frequent speed changes or quick direction reversals, such as plowing or hauling.
  
• Hydraulics
  Equipped with a strong hydraulic system, the 3820 Series A allows the attachment of various implements, such as plows, cultivators, and trailers, making it a versatile tool for modern farming needs. The tractor features a hydraulic flow of approximately 16 gpm, which allows for the efficient operation of larger attachments.
  
• Dimensions and Weight
  The IH 3820 Series A has an overall length of around 12 feet (3.66 meters) and a width of approximately 6 feet (1.83 meters). The tractor’s weight is around 5,500 pounds (2,500 kg), making it a sturdy and stable machine for tough jobs while maintaining maneuverability in tight spaces.
  
• Fuel Capacity
  With a fuel tank capacity of approximately 30 gallons (114 liters), the 3820 Series A is capable of running for extended hours on larger jobs, making it ideal for those long farming days when refueling may be less frequent.
  

Applications and Uses
The IH 3820 Series A was built for versatility. Some common uses include:

• Plowing
  Thanks to its 50 horsepower engine, the 3820 could pull large plows through even dense, compact soil, making it a useful tool for preparing fields for planting.
  
• Harrowing and Cultivating
  The tractor’s hydraulics and weight provide sufficient support to handle heavy harrowing implements, which are essential for breaking up soil after plowing.
  
• Hauling and Towing
  With its rear hitch and powerful transmission, the 3820 Series A is capable of towing a variety of farm implements, including trailers, wagons, and carts.
  
• Field Maintenance
  The tractor was also used for general field maintenance, including cutting grass, hauling debris, and maintaining roads and paths within large farms.
  

Maintenance and Common Issues
To ensure the longevity and optimal performance of the IH 3820 Series A, regular maintenance is crucial. Below are some general maintenance tips, as well as common issues faced by operators:

1. Engine Care
   • Regularly check the oil level and replace the oil at intervals recommended by the manufacturer to ensure engine longevity.
     
   • Inspect the air filter and clean or replace it when necessary. A clogged air filter can reduce engine performance and efficiency.
     
   • Always check the coolant levels and ensure there are no leaks in the radiator or hoses.
     
2. Hydraulic System
   • Check hydraulic fluid levels regularly and replace the fluid according to the maintenance schedule.
     
   • Inspect hydraulic hoses and connections for leaks, wear, or cracks. Leaks can reduce the efficiency of the hydraulic system and cause costly repairs.
     
   • Regularly check the hydraulic cylinders for proper operation and smooth movement.
     
3. Transmission and Gear System
   • Ensure that the transmission is shifting smoothly. If the tractor experiences difficulty shifting, it may be a sign of low transmission fluid or a mechanical issue within the gear system.
     
   • The gear linkage should be lubricated periodically to ensure smooth operation and prevent wear over time.
     
4. Battery and Electrical System
   • Inspect the battery terminals for corrosion and clean them if necessary.
     
   • Check the charging system regularly to ensure the battery is being properly charged. A failing alternator can lead to electrical system issues.
     
   • Ensure that all wiring is intact and free of wear to avoid short circuits and other electrical problems.
     
5. Common Troubleshooting Issues
   • Starting Issues: If the tractor struggles to start, it could be due to a dead battery, a faulty starter motor, or clogged fuel injectors. Check all related components and ensure the battery is fully charged.
     
   • Hydraulic Problems: If the hydraulic system is not operating correctly, it may be caused by low fluid levels, air trapped in the system, or a faulty pump. Regularly inspect and maintain the hydraulic system to avoid issues.
     
   • Overheating: If the engine is overheating, check the coolant level and inspect the radiator for blockages. Additionally, ensure that the thermostat is functioning properly.
     

Conclusion
The IH 3820 Series A is a versatile and reliable piece of machinery, widely used in a variety of farming tasks. While it may no longer be in production, the legacy of the tractor lives on through its many applications and widespread usage in agricultural communities. With proper care and maintenance, the IH 3820 can continue to provide dependable service for years to come, contributing to the productivity and efficiency of small to medium-sized farms. Whether handling soil preparation, hauling, or general farm maintenance, the 3820 Series A continues to be a valuable tool for operators worldwide.
