Introduction: Choosing the Right Used Dozer
Purchasing a used dozer can be a smart investment for construction companies, landscapers, or anyone in need of powerful earth-moving equipment. Two well-known brands in the dozer market are Case and John Deere, both offering reliable models that have stood the test of time. However, buying used equipment requires careful inspection and consideration of several factors to ensure you’re getting a good deal and a machine that will serve you well for years.
In this guide, we will explore some key considerations when buying used Case and John Deere dozers, including the pros and cons of each brand, common issues to look out for, and tips for inspecting used machinery.
Case Dozers: Robust and Reliable
Case Construction Equipment has been around for more than a century, and its dozers are well-regarded for their durability and performance. Case dozers are known for their heavy-duty build, smooth controls, and efficiency in various construction applications, including grading, excavation, and land clearing.
Popular Models to Consider

1. Case 570N Tractor Dozer
   The Case 570N series offers great versatility with a strong balance of power and fuel efficiency. This model is often used in construction sites, especially for mid-level grading tasks. The 570N is equipped with a powerful engine and features hydraulic systems that are known for their reliability.
   
2. Case 570M Series
   For those looking for a smaller machine, the 570M series is an excellent choice. It’s ideal for tight spaces and can deliver impressive maneuverability. Despite its size, it doesn’t compromise on power, making it a solid choice for projects where space constraints are a concern.
   

Pros of Case Dozers

• Durability: Case dozers are built to withstand harsh conditions, making them reliable in long-term use.
  
• Versatility: They can handle a variety of tasks, from heavy lifting to fine grading.
  
• Ease of Operation: Case machines are designed for comfort and ease of control, which is beneficial for operators who work long hours.
  

Common Issues in Used Case Dozers
While Case dozers are generally reliable, it’s important to inspect a used machine thoroughly before purchase. Some common issues that may arise include:

• Transmission Problems: The transmission system in older models can sometimes develop issues with shifting, especially if the dozer has been overworked or poorly maintained.
  
• Hydraulic Leaks: Look for signs of hydraulic fluid leaks, especially around the cylinders and hoses.
  
• Track Wear: Dozers rely heavily on their tracks, so ensure that the track system is in good condition. Worn tracks can be a significant repair cost.
  

John Deere Dozers: Power and Precision
John Deere has earned a strong reputation in the dozer market, especially for its high-powered machines that are built to perform in the most demanding conditions. Known for their reliability, precision, and operator-friendly features, John Deere dozers are often favored by professionals for heavy-duty tasks, including mining, grading, and forestry.
Popular Models to Consider

1. John Deere 700K Crawler Dozer
   The 700K is a versatile, powerful dozer that delivers high performance for both large-scale construction projects and smaller jobs. With its advanced hydraulic system and precise controls, it’s a top choice for operators who value power and efficiency.
   
2. John Deere 850K Crawler Dozer
   For larger tasks, the 850K is a great option. It’s equipped with a powerful engine and advanced technology for better fuel efficiency and easier maintenance. This model is often used in heavy construction and mining operations due to its ability to move large amounts of material quickly and efficiently.
   

Pros of John Deere Dozers

• Advanced Technology: John Deere dozers often feature advanced systems like AutoTrac and JDLink, which help improve productivity and reduce downtime.
  
• Operator Comfort: These dozers are known for their ergonomic design, offering a more comfortable working environment for operators.
  
• Fuel Efficiency: The newer models of John Deere dozers come with fuel-efficient engines, reducing long-term operating costs.
  

Common Issues in Used John Deere Dozers
While John Deere dozers are known for their reliability, used models may still have some issues. Here are a few things to watch for:

• Engine Overheating: Overheating can be a common issue, especially if the dozer has been working in high-stress environments without proper maintenance.
  
• Hydraulic System Issues: As with any dozer, the hydraulic system is critical. Look for any signs of fluid leaks or jerky movements in the hydraulics.
  
• Track and Undercarriage Wear: The undercarriage, including tracks and rollers, can be prone to wear. Ensure that these components are in good condition before making a purchase.
  

Key Considerations When Buying Used Dozers
When buying a used Case or John Deere dozer, several factors will help you make an informed decision:

1. Age and Hours of Use
   The age of the dozer and the number of hours it has been used are key indicators of its remaining lifespan. Generally, dozers with fewer than 5,000 hours are considered low-hour machines, while those with over 8,000 hours may show signs of wear and require more frequent repairs.
   
2. Maintenance History
   Always ask for the maintenance records of the used machine. A well-maintained dozer is likely to last longer and perform better than one that has been neglected. Look for regular oil changes, hydraulic fluid replacements, and other routine service.
   
3. Inspect the Tracks and Undercarriage
   The tracks and undercarriage of a dozer are some of the most expensive components to replace. Check for excessive wear, cracks, and missing parts. A quick inspection of the undercarriage can save you from a costly repair down the road.
   
4. Hydraulic System Check
   Ensure that the hydraulic system is functioning properly. Look for leaks, check fluid levels, and test the hydraulic functions (e.g., blade operation, lift, and tilt). A hydraulic failure can lead to costly repairs if not addressed early.
   
5. Test Drive and Inspection
   Before purchasing, take the dozer for a test run. Pay attention to how it handles, how smoothly it operates, and whether there are any strange sounds or jerky movements. If you're not familiar with machinery, consider bringing a mechanic or expert to inspect the dozer.
   

Comparing Case vs. John Deere Dozers
Both Case and John Deere offer high-quality dozers with unique features and advantages. The choice between the two often comes down to personal preference, the type of work you do, and the specific needs of your job site. Here’s a quick comparison:

• Case Dozers are known for their simplicity, robust design, and ease of use. They are a good option for general construction tasks and are particularly effective in urban and smaller-scale projects.
  
• John Deere Dozers, on the other hand, offer more advanced technology and are built for larger, more demanding tasks. They’re a great choice for heavy-duty work like mining, large-scale grading, and land clearing.
  

Conclusion: Making the Right Choice
Choosing between a used Case or John Deere dozer comes down to understanding your specific needs and the machine’s condition. Both brands offer reliable and powerful dozers, but it’s important to carefully inspect each model you are considering to ensure that you’re getting good value for your money.
If you’re looking for a dozer that offers solid performance in a variety of settings, both Case and John Deere have excellent options.
