The Case 580 SL backhoe, a popular choice for construction and excavation work, is known for its durability and versatility. However, some operators prefer the simplicity and ease of a 2-stick control system over the more complex 4-stick system. This article explores the process of converting a Case 580 SL backhoe from a 4-stick to a 2-stick control system, along with the advantages and challenges involved.
Understanding the 4-Stick and 2-Stick Control Systems
Before delving into the conversion process, it’s important to understand the difference between the two control systems.
4-Stick System
The 4-stick control system is commonly found in older backhoe models. It consists of four levers: two for controlling the boom and dipper (primary movement) and two for the bucket and stabilizers. This setup offers more precise control over each individual movement but can be more cumbersome for operators who prefer a simpler system.
The 2-stick control system is designed to simplify the operation of the backhoe. With only two levers, the operator can control all the primary functions: the boom, dipper, and bucket. This setup reduces the number of levers, making it easier for operators to manage the machine.
The decision to convert a 4-stick system to a 2-stick system is usually driven by operator preference. While the 4-stick system offers precision, many operators prefer the simplicity and ease of the 2-stick system. Some reasons for converting include:
The Conversion Process
Converting a Case 580 SL from a 4-stick to a 2-stick control system requires careful planning and a solid understanding of the machine’s hydraulic and control systems. Here are the general steps involved:
Step 1: Gather the Necessary Parts
Before starting the conversion, it’s essential to gather all the required components. This typically includes:
The first step is to remove the existing 4-stick control system. This will involve detaching the levers from the control mechanism and carefully removing them from the operator’s console. Depending on the model, this could also involve disconnecting hydraulic lines and electrical connections that control the individual movements of the backhoe.
Step 3: Install the 2-Stick Control Levers
Next, install the new 2-stick control levers. These levers are usually mounted in the same location as the old levers but require adjustments to accommodate the new hydraulic and electrical systems. The 2-stick system combines the functions of the previous four levers into two, which requires a different setup for controlling the hydraulic valves.
Step 4: Modify the Hydraulic and Electrical Systems
This step is the most technical part of the conversion. The hydraulic systems need to be re-routed to match the new control layout. The two levers must now control multiple hydraulic functions, which means the hydraulic valves will need to be modified or replaced with a valve block that accommodates the new system.
Electrical systems may also need modification, particularly if there are any electrical sensors or switches tied to the controls. It’s essential to ensure all electrical connections are correctly made to avoid malfunctions.
Step 5: Test the New System
Once the conversion is complete, it’s time to test the new 2-stick system. Test all functions of the backhoe to ensure that the hydraulic system operates smoothly and that the controls respond correctly. Pay close attention to how the boom, dipper, and bucket react to the new controls.
It’s also important to ensure that the backhoe’s safety features (such as lockout systems) are functioning properly after the conversion.
Real-World Example: Case 580 SL Conversion
A user shared their experience of converting their Case 580 SL backhoe from a 4-stick system to a 2-stick system on a popular online heavy equipment forum. After struggling with the complexity of the 4-stick controls, they decided to make the switch in hopes of improving comfort and efficiency on the job site.
The process took several days to complete and required both mechanical expertise and a good understanding of the machine’s hydraulic system. After completing the conversion, the operator found the backhoe much easier to handle. They reported less arm and hand fatigue, especially during long workdays, and found the 2-stick system to be more intuitive.
Benefits of Converting to a 2-Stick System
While the benefits are significant, the conversion also comes with a few challenges:
Converting a Case 580 SL from a 4-stick to a 2-stick control system can significantly enhance the operator's comfort and make the backhoe easier to use. The process, however, requires careful planning and technical expertise to ensure that all systems work correctly after the conversion. For those seeking simplicity, reduced operator fatigue, and more intuitive controls, switching to a 2-stick system can be a worthwhile upgrade, but it’s important to weigh the benefits against the costs and potential challenges.

This setup offers more precise control over each individual movement but can be more cumbersome for operators who prefer a simpler system.
- Advantages: The 4-stick system provides precise control over individual functions, which can be beneficial for delicate work.
- Disadvantages: The system is more complicated and requires more coordination. Operators must manage multiple levers, which can be challenging, especially for those new to backhoe operation.
The 2-stick control system is designed to simplify the operation of the backhoe. With only two levers, the operator can control all the primary functions: the boom, dipper, and bucket. This setup reduces the number of levers, making it easier for operators to manage the machine.
- Advantages: Easier to operate with less hand and arm movement. It’s a more streamlined system that many operators find more comfortable, especially for long hours of use.
- Disadvantages: It may sacrifice a bit of precision in individual control compared to the 4-stick system, as multiple functions are controlled by one lever.
The decision to convert a 4-stick system to a 2-stick system is usually driven by operator preference. While the 4-stick system offers precision, many operators prefer the simplicity and ease of the 2-stick system. Some reasons for converting include:
- Ease of Use: Newer operators or those with limited experience may find the 2-stick system easier to master.
- Comfort: The 2-stick system reduces the amount of hand and arm movement required, which can reduce operator fatigue during long hours of operation.
- Efficiency: For certain tasks, the 2-stick system can increase efficiency by simplifying the controls.

Step 1: Gather the Necessary Parts
Before starting the conversion, it’s essential to gather all the required components. This typically includes:
- 2-stick control levers (often available as a kit from the manufacturer or aftermarket suppliers)
- Hydraulic control valves or a valve block
