When it comes to purchasing a used dozer, there are several factors that need to be carefully considered to ensure you're getting a machine that will perform reliably and serve you well for years to come. Whether you are a seasoned operator or new to the world of heavy equipment, choosing the right dozer can make a significant difference in the efficiency and cost-effectiveness of your operations. This article will explore how to find a good older dozer, what key factors to consider, and share some practical advice and examples to help you make an informed decision.
Why Choose an Older Dozer?
The first question many buyers ask is why choose an older dozer rather than investing in a newer model. The reasons are varied, but they typically include cost savings, simplicity, and availability of parts.
When you’re in the market for a used dozer, there are several things to keep in mind to ensure you're making a wise investment:
1. Age and Hours
One of the most critical factors when buying an older dozer is the machine's age and the number of operating hours it has been used. While dozers can last for many years, heavy equipment is typically evaluated based on the number of hours it has been run. A well-maintained dozer with 5,000 hours might be more valuable than one with 1,000 hours but poor maintenance records.
Look for machines that have been regularly serviced and have a documented service history. Dozers that have been used heavily in more demanding environments, such as quarries or heavy construction sites, will likely show more wear than those used on lighter tasks, such as landscaping or land clearing.
2. Condition of the Undercarriage
The undercarriage of a dozer is one of the most important areas to inspect. A worn-out undercarriage can be expensive to repair and significantly affect the performance of the machine. Check the tracks, rollers, sprockets, and idlers for wear. Inspect the tension of the tracks as well—if they are too loose or too tight, it could indicate a need for repair or replacement.
3. Engine and Hydraulics
The engine and hydraulic systems are the heart of any dozer. Inspect the engine for leaks, unusual noises, and performance issues. Check the oil, coolant levels, and overall engine condition. Ask for a detailed service record and verify if the engine has been rebuilt or overhauled, as this could be an indication that it has been well-maintained.
Similarly, inspect the hydraulic systems to ensure that there are no leaks and that all hydraulic cylinders are functioning properly. Hydraulic failures can be costly, so ensuring the hydraulic system is in good condition is essential.
4. Cabs and Controls
Inspect the operator’s cab for comfort and functionality. A well-maintained dozer should have clear visibility, comfortable seating, and working controls. Pay attention to any cracks, rust, or other signs of neglect. Modern features such as air conditioning, radio systems, and ergonomic seating may not be present in older models, but it's still important to ensure that the basic controls and systems are fully functional.
5. Attachments and Features
Some older dozers come with additional attachments, such as rippers, blades, or winches, which can significantly add to the machine’s value. Be sure to check whether the dozer has these features and whether they are in good working condition.
Examples of Reliable Older Dozers
There are several well-known brands and models that have gained a reputation for being durable and reliable even after many years of use. Here are a few examples:
Finding the right used dozer requires searching in the right places. Here are a few methods to consider:
In many ways, buying an older dozer is like buying any used piece of machinery—it’s all about knowing what to look for. Older dozers can be an excellent investment if you take the time to thoroughly inspect them and verify their history. While they may not come with the bells and whistles of newer models, their simplicity and durability can often make them more cost-effective in the long run.
By paying attention to the key aspects of a used dozer, such as its hours, condition of the undercarriage, engine performance, and hydraulics, you can ensure that you’re investing in a machine that will serve you for years to come.
Why Choose an Older Dozer?
The first question many buyers ask is why choose an older dozer rather than investing in a newer model. The reasons are varied, but they typically include cost savings, simplicity, and availability of parts.
- Cost-Effectiveness: Older dozers are often more affordable compared to new models. For many small businesses or independent contractors, the initial capital investment of a brand-new dozer is simply out of reach. An older model, if well-maintained, can still provide excellent value at a fraction of the price.
- Simplicity and Durability: Many older models have fewer complex systems and electronics, which means they can be easier to repair and maintain. While newer dozers may offer advanced features and efficiency improvements, the simplicity of an older dozer can be an asset, especially for those working in remote areas or on smaller jobs where cutting-edge technology isn’t necessary.
- Parts Availability: With older dozers, finding replacement parts can often be easier. Brands like Caterpillar and Komatsu have long histories, and parts for older machines are still commonly available either from the manufacturer or aftermarket suppliers. This can be a big plus for minimizing downtime during repairs.

Examples of Reliable Older Dozers
There are several well-known brands and models that have gained a reputation for being durable and reliable even after many years of use. Here are a few examples:
- Caterpillar D6 and D7 Series: These models are often considered the workhorses of the dozer world. Even older models, such as the D6H and D7G, are still highly sought after due to their durability and relatively simple maintenance needs. Many owners swear by the D7E, a popular model from the early 1980s, still in service today.
- Komatsu D65: Known for its power and versatility, the D65 is a favorite in the construction and mining sectors. With proper care, these dozers can run for many years, making them a great option for those seeking value in older models.
- John Deere 750C: For those who prefer a more affordable alternative, the John Deere 750C is another excellent option. It has a reliable engine and undercarriage, making it a popular choice for both land clearing and construction tasks.
Finding the right used dozer requires searching in the right places. Here are a few methods to consider:
- Dealerships: Many dealerships that specialize in heavy equipment offer used dozers, often with service histories, warranties, and maintenance records.
- Online Auctions: Websites like IronPlanet, Ritchie Bros. Auctioneers, and eBay often feature older dozers for sale, where you can sometimes find great deals.
- Local Dealers and Private Sellers: Sometimes local dealerships or private sellers offer dozers that are in good working condition and are priced competitively.
