5 Tips for Buying a Used Dozer | RDO Equipment Co.

Go online. Find the perfect fit. Hit the ‘buy now’ button. The purchase arrives promptly and ready to go. Imagine this process for buying a used dozer. 

While online used equipment shopping may not be quite this easy, the process to buy used machines has come a long way from newspaper classifieds and the first live auctions. Especially this year, as customers have needed and demanded more contact-free shopping experiences, the opportunities to research, browse, then buy equipment online have become even better.

Used equipment is especially popular right now and dozers are one of those necessary, high-production machines essential on most jobsites. Those interested in expanding their fleets can read on for five steps to find and buy a high-quality used dozer.

1. Finding the Right Seller
One of the best places to find a used dozer is also one of the most familiar – a trusted equipment dealership. Dealer rental fleets are growing. Reputable ones back up the machine with parts and service support, long after the sale. Combined with the quality care and preventative maintenance (PM) dealers put into their machines, companies are able to find the quality used dozer they’re looking for.

There are other options, including private sellers and auctions. However, both require a bit more research to ensure they’re offering good machines with ethical transparency. 

Auctions typically offer the largest quantity of used equipment in one place, great for more selection or those looking for multiple machines. However, buying at auction also comes with unique concerns and risks. Companies that struggle to sell used dozers on their own often look to auctions as a last resort. There’s also no recourse for buyers who end up with a machine that has hidden problems.

When it comes to private sellers, ask around, search for online reviews, and do a little more digging into the seller’s history. Look for red flags such as bad peer reviews, unethical business practices, even records of stolen equipment.

If choosing the route of a private seller, keep in mind his or her goal is to sell the dozer, regardless if it’s a good fit. Keep in mind, a trusted equipment dealer will have a larger inventory and options to choose from. And there will be a vested interest in finding a good fit to create a happy, satisfied, repeat customer. 

2. Research and Browse 
Just as there are numerous sellers of used equipment, there are several avenues an interested buyer can explore to see what’s out there. 

Online shopping reigns supreme, especially in today’s contact-free buying environment. Websites have evolved to be more search-friendly so it’s easy to seek out exactly what’s desired. This includes anything from make and model to technology upgrades on machines like Deere and Topcon’s SmartGrade dozer. Online also offers the most up-to-date inventory selection. And of course there’s the convenience of researching and browsing at home on the couch. 

Speaking of research, most manufacturers have informative comparison and research tools on their sites. RDO Equipment Co. has also expanded its site to include photos, even some video walkarounds of machines, or they can be requested. Those who feel more comfortable purchasing a used dozer at a local dealership can go in with some background on what they’re looking for and what’s out there in the market.

While newspaper classifieds and magazine ads are still used, keep in mind online typically presents the most accurate, up-to-date offerings available.

3. Timing is Everything 
Some industries, agriculture for example, have seasonal factors that affect used equipment availability and price. The construction industry typically doesn’t see those same seasonal factors, however, timing is still important when it comes to finding a good machine and getting a good price. 

Companies should look 30-60 days ahead to see if there’s an expected uptick in their work or a certain type of project coming up that would require the addition of a dozer. This window allows enough time to search options and find what’s desired rather than settle for what’s available last-minute. In the case of working with a dealership that does a lot of rental business, there may be a dozer coming in and offering a unique opportunity to purchase a machine from the dealer’s rental fleet.

A smart buyer will also stay up-to-date on what’s happening in the industry overall, as market trends often dictate the equipment market. This year has been an interesting one – and certainly one unlike any other – but there’s still opportunity to watch auction prices, keep tabs on new equipment sale prices, and monitor other online used equipment prices.

4. Don’t Forget the Details
When the right make and model dozer is found from a quality seller, it’s a green light to buy, right? Not quite. A thorough investigation must be conducted before buying a used dozer. 

While the COVID-19 pandemic has made it easier to find more options online, it’s now a bit more difficult to see dozers in person to do visual walkarounds and even jump into the cab for a test drive. But there are still ways to 

First, every buyer should ask to see a full evaluation of the dozer, including hours, records of maintenance intervals, and complete history of the machine and its applications. Ask for additional photos and video – on top of what was available in the online listing – that go into more detail of the machine and those that document major repairs and significant work done. While private sellers or auctions might not be able to provide this level of documentation, reputable dealerships will have full service records, and history of all PM and repairs done on every machine.

When looking at walkaround videos and detailed photos, look for signs of wear, beyond what would be normal and expected for the machine’s hours and previous applications. Excessive track wear and, especially undercarriage wear, are concerning. If not addressed, both could lead to bigger problems, sometimes a full – and expensive – undercarriage replacement. Additional red-flag items are cracks, rust, and leaks. 

Watch two RDO experts discuss the importance of an undercarriage evaluation – something you can request via video if buying a used dozer from RDO.

As most equipment operators and buyers know, machine age isn’t as much a concern as its hours. This is another example of where research and the machine’s undercarriage can be key points in finding the best deal. 

A machine with 1,500-2,000 hours on it should have quite a bit of undercarriage wear left on it, as well as plenty of life left in the engine and hydraulic components, which would meet the criteria to make it a good buy. But don’t rule out an older machine. A dozer with more than 4,000 hours on it that has a recent undercarriage replacement and still has good life left in the engine and hydraulics might be an even better buy. In many cases, warranties follow the machine and typically go to 5,000 or more hours.

5. Maintenance Matters
The final tip for buying a used dozer actually happens long after the machine secures its place in the company’s fleet. As with new equipment, regular maintenance for used dozers is important to protect the investment and extend the machine’s life. And a little effort goes a long way. 

At its most basic, a good PM program can be boiled down to five key steps:
-Daily, visual inspection of the machine before starting, checking for red flags like cracks and leaks
-Daily check and refill of fluids
-Daily greasing of crucial points
-Regular check of the engine, including its air and fuel filters
-Regular documentation of maintenance activities, including significant work and repairs

For companies that don’t have the number of people or those with the right skills to effectively maintain equipment, keep in mind even these basic efforts can go a long way. This is also where buying from a reputable equipment dealer again comes out ahead, as the dealership’s skilled, certified technicians can provide everything from basic preventative maintenance care and repairs all the way up to remote machine monitoring and troubleshooting, and annual, thorough equipment inspections.

Research, Browse, Buy with Confidence
From diversification to growth opportunities, there are several reasons buying a used dozer is the best choice for a company and its fleet. Because every machine – and seller – is on a different level, buyers must make extra efforts to do the right research and follow through. Thanks to new opportunities for browsing and contact-free buying, used dozer seekers have greater ability to make a confident buying decision.

Used Dozer Buying Guide - Black Star

Research and Preparation


If you're in the market for a used bulldozer (dozer), it's important to do your research to ensure that you make a wise investment.

Buying a used dozer can be a cost-effective option for many buyers, but it's important to be aware of the potential risks and pitfalls that can come with buying used equipment. With the right information at your fingertips and knowing what to look for, you can make an informed decision and buy a great used dozer that meets your needs and fits your budget.

In this article we discuss:

  • Getting ready to buy
  • Equipment inspection
  • Project considerations
  • Comparing dozers

For more information on dozers, check out Bulldozers: What You Need to Know.

Getting ready to buy


When preparing to buy a used dozer, here are six key factors to consider:

  1. Your specific needs: Think about the tasks that you will be using the dozer for, and make sure that the machine you choose is capable of handling them. Consider the size and power of the dozer, the type of blade, and any additional features you may need.
  2. Budget: Determine how much you are willing to spend, taking into account any potential maintenance or repair costs.
  3. Age and usage history: A newer machine may have fewer hours of operation and may be in better condition, but it may also come with a higher price tag. An older machine may be more affordable but may require more maintenance and repairs.
  4. Condition: Look for signs of wear and tear, and inspect the engine, transmission, and hydraulic systems. You may want to consider hiring a professional inspector or mechanic to give the machine a thorough evaluation.
  5. Seller reputation: Do your research on the seller or dealer you are considering purchasing from. Look for reviews and ratings from previous customers, and make sure the seller is reputable and trustworthy.
  6. Availability of parts and service: If replacement parts are difficult to find or the servicing is expensive, it may not be the best option for you.

Inspecting the Dozer


To get a good idea of the condition of the equipment, it is important to inspect the following components:

  • Undercarriage: Include the tracks, rollers, sprockets, and idlers. Check for signs of wear and tear, such as worn or cracked rubber, damaged track links, and loose or damaged rollers. The undercarriage is one of the most expensive parts of a dozer to repair or replace, so it's important to pay close attention to this area.
  • Engine: Check for signs of damage or leaks. Look for rust, corrosion, or any other signs of wear and tear. Check the oil and coolant levels and listen for any unusual noises when the engine is running.
  • Transmission: Inspect for any signs of wear and tear and check the fluid levels. Test the gears and clutches to ensure they're working properly.
  • Hydraulics: Check for any leaks or damage to the hoses and cylinders. Test the blade and any other hydraulic systems, such as rippers or winches, to ensure that they're functioning properly.
  • Blade: Inspect for any signs of wear and damage, including cracks or bends, and test the blade angle and tilt functions.
  • Cab: Check any damage or wear, including the seat, steering wheel, pedals, and gauges. Make sure that all the controls are working properly.
  • Service and maintenance records: Ask the seller for service and maintenance records to determine if the machine has been well-maintained.

Consider a professional inspection to ensure that nothing is overlooked or missed.

Project Considerations


To make sure you get the right used dozer, here are five considerations:

  1. Job type: If you're working on rough terrain, you'll need a bulldozer with good traction and a sturdy undercarriage. If you're working in a confined space, you may need a smaller dozer that's more maneuverable.
  2. Site conditions: If you're working in a muddy or wet environment, you may need wider tracks to provide better flotation. If you're working on rocky terrain, you'll need  a strong blade that can handle the rocks.
  3. Size: Larger dozers are generally more powerful and can handle bigger jobs, but may not be practical for smaller job sites. Smaller dozers may not have the power or capabilities needed for larger jobs.
  4. Transport to a job site: If you're transporting the dozer on a trailer, make sure the trailer is rated for the weight of the dozer and that the dozer can be safely loaded and unloaded.
  5. Cost: Used dozers can be good value, but make sure to factor in any repair or maintenance costs. It may be worth spending more upfront on a higher quality machine if it will save you money in the long run.

Comparing dozers

Once you have taken into account your project needs, you may want to compare the different dozer brands and models to determine how well they have performed over their lifetime so far, and the condition they are currently in.

You ultimately want to choose a brand that will meet your needs and provide reliable performance for any of your projects. Compare:

  • Age and hours: Look for brands that are known for producing machines that are durable and long-lasting, even with high hours.
  • Condition: Look for brands that are known for producing machines that are easy to maintain and repair, and that have a good reputation for durability.
  • Service and maintenance history: Look for brands that have a good reputation for reliability and that have been well-maintained by previous owners.
  • Availability of parts: Look for brands that have a good supply chain for replacement parts, so you can get the parts you need quickly and easily.
  • Price: Look for brands that offer a good value for the price, with a balance of performance, features, and affordability.
  • Resale value: Look for brands that hold their value well over time, so you can recoup some of your investment if you decide to sell the dozer later.


It is important to choose a brand with a strong reputation for quality and reliability. Some popular manufacturers include John Deere, Komatsu, and Caterpillar. Check out our dozer category page to find out more and see what dozers we have available to buy now.

Before you purchase


Before purchasing any equipment, it is important to inspect it if possible (or have it inspected) and understand its condition, maintenance history, and any potential repair costs.

Searching for used dozers


Finding the equipment you need can be time-consuming. Here are some ways to locate used dozers, or any other heavy equipment for sale:

  • Online marketplaces: There are many online marketplaces that specialize in buying and selling used equipment. You can search for equipment by type, brand, model, location, and price range.
  • Auction websites: Some auction websites specialize in selling used heavy equipment. These websites allow you to search for equipment by category, manufacturer, location, and auction date.
  • Classified ads: You can also search for used equipment on classified ad websites. These websites allow you to search for equipment by type, location, and price range.
  • Dealerships: Many equipment dealerships sell both new and used equipment. You can find local dealerships by doing a search online.
  • Industry publications: Trade publications often have classified ads for used equipment. You can also find equipment listings in these publications' online versions or print versions if you sign-up to receive them.
  • Social media: Some social media platforms have groups dedicated to buying and selling used equipment. You can search for these groups by using relevant keywords and joining groups that are relevant to your industry.

Where to purchase


Purchasing options include:

  • Dealerships: Many heavy equipment dealerships sell both new and used equipment. These dealerships may offer warranties or financing options for used equipment.
  • Online marketplaces: Some online marketplaces specialize in selling used heavy equipment. Buyers can browse through listings and communicate directly with sellers.

Financing your dozer


If you need financing for your purchase, consider these options:

  • Equipment financing companies: These companies may offer a variety of financing options, such as leases, loans, and lines of credit.
  • Equipment dealerships: Some heavy equipment dealerships offer financing options for both new and used equipment. These dealerships may have relationships with financing companies or may offer in-house financing options.
  • Banks and credit unions: These traditional lenders may offer options but may also have specific requirements and could require collateral for the loan.
  • Online lenders: These lenders may offer more flexible terms and may be quicker to approve loans.


Compare interest rates, terms, and fees from multiple lenders. It is important to have a good understanding of your financial situation and budget to ensure that you can make payments on time.
