Thinking about buying an International Harvester (IH) 674 diesel tractor? You're not alone! This model, produced from the early to late 1970s, has a solid reputation, but like any piece of machinery of that age, it's crucial to know what you're getting into. This article will dig deep into the IH 674, exploring its strengths, weaknesses, and everything in between to help you decide if it's the right tractor for your needs.

What Makes the IH 674 a Popular Choice?

The IH 674 earned its stripes through a combination of factors that appealed to farmers and landowners alike. Let's break down why this tractor remains a sought-after classic:

  • Reliable Engine: The heart of the 674 is its diesel engine, typically a four-cylinder unit. These engines are known for their durability and ability to deliver consistent power. They're not the most fuel-efficient by modern standards, but they are relatively simple to maintain and repair.
  • Versatile Size and Power: The 674 falls into a sweet spot in terms of size and horsepower. It's big enough to handle a variety of tasks, from plowing and tilling to mowing and loader work, yet small enough to maneuver in tighter spaces. This makes it a good choice for small to medium-sized farms, hobby farms, or even large properties that need a utility tractor.
  • Simple Design: Unlike many modern tractors loaded with electronics, the IH 674 is mechanically straightforward. This simplicity translates to easier troubleshooting and repairs. Most experienced mechanics (and even mechanically inclined owners) can work on these tractors without needing specialized diagnostic equipment.
  • Availability of Parts: Because the IH 674 was a popular model, parts are still relatively easy to find. Aftermarket suppliers and salvage yards offer a wide range of components, making it easier to keep these tractors running.
  • Affordable Price Point: Compared to newer tractors with similar capabilities, the IH 674 often comes with a significantly lower price tag. This makes it an attractive option for buyers on a budget.

But It's an Old Tractor...What Are the Potential Downsides?

While the IH 674 has a lot going for it, it's essential to be aware of the potential drawbacks that come with owning a tractor of this age:

  • Age-Related Wear and Tear: This is the most obvious concern. Any tractor from the 1970s will have accumulated wear and tear over the years. Expect to find some rust, worn-out components, and potentially leaky seals. A thorough inspection is crucial before buying.
  • Lack of Modern Features: Don't expect the creature comforts of a modern tractor. The IH 674 typically lacks features like air conditioning, power steering (on some models), and advanced hydraulic systems.
  • Potential for High Maintenance Costs: While parts are generally available, repairs can still be costly, especially if major components like the engine or transmission need work. Budget for potential maintenance costs when considering the purchase price.
  • Lower Fuel Efficiency: As mentioned earlier, older diesel engines are not as fuel-efficient as their modern counterparts. This can add up over time, especially if you use the tractor frequently.
  • Limited Safety Features: Compared to modern tractors, the IH 674 may have fewer safety features. Be sure to understand the tractor's operation and take appropriate safety precautions.

Diving Deeper: Key Components to Inspect Before Buying

If you're seriously considering an IH 674, a thorough inspection is paramount. Here's a breakdown of the key areas to focus on:

  • Engine: Start the engine and listen carefully for any unusual noises, such as knocking or excessive smoke. Check the oil pressure and temperature gauges. Look for leaks around the engine block, head, and oil pan. A compression test can give you a better idea of the engine's overall health. Black smoke usually indicates too much fuel or not enough air, while blue smoke suggests oil burning. White smoke can indicate water in the combustion chamber.
  • Transmission: Shift through all the gears and listen for any grinding or slipping. Check the transmission fluid level and condition. Look for leaks around the transmission housing and axles. Pay close attention to the gear shifting. It should be smooth and without excessive noise.
  • Hydraulics: Operate the hydraulic lift arms and any remote hydraulic outlets. Check for smooth and responsive operation. Look for leaks around the hydraulic pump, cylinders, and hoses. Hydraulic problems can be expensive to repair.
  • Brakes: Test the brakes on both sides of the tractor. They should be firm and responsive. Check the brake fluid level and condition. Uneven braking can indicate worn brake linings or other problems.
  • Steering: Check for excessive play in the steering wheel. The steering should be smooth and responsive. Look for leaks around the steering box and tie rod ends. Power steering, if equipped, should operate smoothly and without excessive noise.
  • Electrical System: Check all the lights, gauges, and starting system. Ensure the battery is in good condition. A weak electrical system can be a sign of underlying problems.
  • Tires: Inspect the tires for wear and damage. Worn or damaged tires can be expensive to replace. Consider the tire size and type for your intended use.
  • Overall Condition: Look for signs of rust, damage, or neglect. Check the condition of the sheet metal, seat, and other components. A well-maintained tractor is usually a good sign of responsible ownership.
  • PTO (Power Take-Off): Engage the PTO and check for smooth and consistent operation. Listen for any unusual noises or vibrations.

Different Models and Variations: Is There a "Best" IH 674?

While the core design remained consistent, there were some variations within the IH 674 model range. These variations primarily related to transmission options, hydraulic configurations, and the presence or absence of certain features.

  • Transmission Options: The IH 674 typically came with a standard gear transmission. Some models may have featured a partial power shift or other variations. The specific transmission type can affect the tractor's performance and ease of use.
  • Hydraulic Systems: Some IH 674 tractors had more advanced hydraulic systems with multiple remote outlets, while others had simpler systems. The hydraulic capacity and configuration are important if you plan to use implements that require hydraulic power.
  • Power Steering: Not all IH 674 tractors were equipped with power steering. Power steering makes the tractor easier to maneuver, especially when operating with a loader.

There isn't necessarily a "best" IH 674, as the ideal model depends on your specific needs and preferences. However, a well-maintained tractor with power steering and a suitable hydraulic system is generally considered more desirable.

What Implements Can the IH 674 Handle?

The IH 674 is a versatile tractor that can handle a wide range of implements, making it suitable for various tasks:

  • Plowing and Tilling: It can handle smaller plows and tillers for preparing soil for planting.
  • Mowing: It's well-suited for operating rotary cutters (bush hogs) and finish mowers for maintaining pastures and lawns.
  • Loader Work: With a front-end loader, it can be used for moving materials like dirt, gravel, and hay bales.
  • Haying: It can power hay balers, rakes, and tedders for hay production.
  • Planting: It can be used with planters for planting various crops.
  • Spraying: It can power sprayers for applying herbicides and pesticides.

The specific implements that the IH 674 can handle will depend on the tractor's horsepower, hydraulic capacity, and three-point hitch capacity.
