Evaluating a Used Case 580K Backhoe Loader Before Making an Offer

[MikePhua]

The 580K and Its Role in Case Construction History
The Case 580K backhoe loader was introduced in the late 1980s as part of Case’s long-running 580 series, which has been a cornerstone of the compact construction equipment market since the 1960s. The 580K succeeded the 580E and preceded the 580L, offering improvements in hydraulic performance, operator comfort, and drivetrain reliability. Case Corporation, founded in 1842, had by then become a global leader in earthmoving machinery, and the 580K was one of its most widely sold models during its production run.
The 580K was available in multiple configurations, including two-wheel drive and four-wheel drive, with optional features such as the extendahoe (a telescoping dipper stick), enclosed cab with heat and AC, and a 4-in-1 multipurpose bucket. Powered by a Cummins 4BTA 3.9L diesel engine, the machine delivered around 75 horsepower and was known for its torque, fuel efficiency, and ease of maintenance.
Terminology Annotation
- Extendahoe: A backhoe arm extension that allows for deeper digging without repositioning the machine.
- 4-in-1 Bucket: A multipurpose front bucket that can be used for dozing, clamping, grading, and loading.
- Carraro Transmission: An Italian-made transmission system used in later-phase 580K models, offering smoother shifting and improved durability over earlier versions.
- Phase 3: A designation for later production units of the 580K, typically built around 1990–1994, featuring upgraded hydraulics and drivetrain components.
Determining Year and Serial Number Relevance
The serial number JJG0029140 places the machine in the later part of the 580K production run, likely around 1990. Earlier models began in the late 1980s, and by the time the 580K was phased out in favor of the 580L in the mid-1990s, Case had produced tens of thousands of units. While exact production numbers are not publicly available, auction data and dealer records suggest that the 580K was one of Case’s best-selling backhoes of its era.
Knowing the year is important for parts compatibility, especially for transmission and hydraulic components. Phase 3 units are generally preferred due to their improved Carraro transmission and refined hydraulic controls.
Market Value and Condition-Based Pricing
Used equipment pricing is highly dependent on condition, configuration, and location. Based on auction data from Ritchie Bros., the Case 580K has sold for:

• High: $20,500
  
• Median: $10,500
  
• Low: $5,500
  

These figures include both 2WD and 4WD models, with varying hours and attachments. A 2WD unit with an extendahoe and 4-in-1 bucket in good cosmetic condition but needing tires and hydraulic hose replacement may be fairly valued around $10,000–$12,000, depending on regional demand.
In the example considered, the seller is asking $15,000 as-is, with estimated repair costs of:

• Rear tires: $1,300
  
• Extendahoe hose replacement: $1,200
  

This brings the total investment to approximately $17,500, which may exceed the market median unless the machine is in exceptional mechanical condition.
A Story from Rural Ontario
A contractor in Ontario was evaluating a 580K located just 10 miles from his property. The proximity was a major advantage, as he could drive the machine home without transport costs. The unit had a clean body, intact glass, and a Cummins engine—features he appreciated, especially since he already owned a Dodge truck with the same powerplant. After researching the serial number and confirming it was a Phase 3 model, he weighed the cost of repairs against the convenience and long-term utility. Ultimately, he negotiated the price down by factoring in the tire and hose replacement, and planned to perform the repairs himself after watching instructional videos.
Recommendations Before Making an Offer
To make an informed offer:

• Verify the serial number and confirm production phase
  
• Inspect for loose pins, worn bushings, and deferred maintenance
  
• Check for hydraulic leaks, especially around the extendahoe
  
• Test transmission responsiveness and brake function
  
• Evaluate tire condition and estimate replacement cost
  
• Confirm that all glass and cab components are intact
  
• Review auction data for similar machines in your region
  
• Factor in transport costs, or value proximity if self-delivery is possible
  

If the machine has a Carraro transmission and a clean body, it may justify a premium over base auction values, especially if the buyer can perform repairs independently.
Conclusion
The Case 580K remains a respected and capable backhoe loader, especially in its Phase 3 configuration. When evaluating a used unit, condition and configuration matter more than production year alone. By verifying serial numbers, assessing repair needs, and comparing auction data, buyers can make confident offers that reflect both market value and operational potential. With its Cummins engine, extendahoe capability, and legacy of reliability, the 580K continues to be a smart investment for contractors and landowners alike.
