The Case 580B CK and Its Historical Significance
The Case 580B Construction King (CK) was introduced in the early 1970s as part of Case’s second-generation backhoe loader lineup. Building on the success of the original 580, the B-series offered improved hydraulics, better operator ergonomics, and a more refined powertrain. With a diesel engine producing around 50 horsepower and a mechanical shuttle transmission, the 580B CK was designed for versatility in trenching, grading, and light excavation.
Case Corporation, founded in 1842, had already established itself as a leader in agricultural and construction equipment. By the time the 580B CK was released, Case had sold tens of thousands of backhoes globally, and the 580 series became one of the most recognizable machines in the industry. The CK designation emphasized its dual-purpose capability—loader in the front, backhoe in the rear—making it ideal for contractors, farmers, and municipalities.
Key Mechanical Features and Operating Characteristics
The 580B CK is a mechanically straightforward machine, which makes it attractive for first-time buyers and those seeking ease of maintenance. Its core features include:
Common Issues and Inspection Points
When evaluating a used 580B CK, pay close attention to:
Despite its age, the 580B CK enjoys strong aftermarket support. Key sources include:
Ownership Experience and Practical Use Cases
The 580B CK excels in:
A Story from the Field
In 2020, a retired mechanic in Vermont purchased a 580B CK to maintain his 40-acre property. The machine had sat idle for five years but started after replacing the batteries and bleeding the fuel system. Over the next season, he used it to dig drainage ditches, move gravel, and clear brush. He later rebuilt the steering box and added a canopy for shade. The machine became a weekend companion and a teaching tool for his grandson.
Conclusion
The Case 580B CK remains a viable choice for first-time backhoe owners seeking a durable, repairable, and affordable machine. While it lacks the hydraulic finesse and comfort of newer models, its mechanical integrity and straightforward design make it a rewarding investment. In the world of used iron, the 580B CK is more than a relic—it’s a workhorse with a legacy. When the levers respond and the bucket bites, the job begins with confidence and ends with pride.

Key Mechanical Features and Operating Characteristics
The 580B CK is a mechanically straightforward machine, which makes it attractive for first-time buyers and those seeking ease of maintenance. Its core features include:
- Engine
Typically equipped with a Case G188D diesel engine, known for reliability and low-end torque. Some units came with gasoline variants, but diesel models are preferred for fuel economy and longevity.
- Transmission
Mechanical shuttle with four forward and reverse gears. The shuttle lever allows quick directional changes, but clutch wear should be monitored.
- Hydraulics
Open-center hydraulic system with gear-driven pump. Flow rates are modest by modern standards but sufficient for trenching and loading.
- Backhoe and Loader
The backhoe offers a digging depth of approximately 14 feet, while the loader bucket capacity is around 0.75 cubic yards. Both ends use mechanical linkages and single-acting cylinders.
- Brakes and Steering
Manual steering and mechanical drum brakes. These systems require regular adjustment and inspection, especially on older units.
Common Issues and Inspection Points
When evaluating a used 580B CK, pay close attention to:
- Hydraulic leaks
Check all cylinder seals, hose connections, and valve blocks. Leaks are common but usually repairable with off-the-shelf parts.
- Transmission wear
Test shuttle engagement under load. Slipping or grinding may indicate clutch or gear damage.
- Steering play
Excessive movement in the steering wheel often points to worn linkages or sector gear wear.
- Brake function
Inspect pedal travel and braking response. Drum brakes may require relining or cable adjustment.
- Electrical system
Many units have been rewired over the years. Look for clean connections and functional gauges.
- Loader frame cracks
Examine welds and pivot points for fatigue, especially near the boom base and bucket linkage.
Despite its age, the 580B CK enjoys strong aftermarket support. Key sources include:
- Salvage yards specializing in Case equipment
- Online suppliers offering reproduction hydraulic cylinders, seals, and filters
- Tractor and industrial parts distributors for engine and transmission components
- Enthusiast communities that share manuals, diagrams, and rebuild tips
Ownership Experience and Practical Use Cases
The 580B CK excels in:
- Small-scale excavation and trenching
- Farm maintenance and material handling
- Driveway grading and culvert installation
- Fence post digging and tree planting
