Case 580ST Backhoe Loader Overview
The Case 580ST is a modern backhoe loader developed by CNH Industrial under the Case Construction Equipment brand. Introduced as part of the European ST series, the 580ST combines the rugged DNA of the legendary Case 580 line with updated hydraulics, emissions-compliant engines, and operator-focused ergonomics. It features a Tier 4 Final engine, powershift transmission, and a closed-center hydraulic system designed for simultaneous loader and backhoe operation.
Case Construction Equipment, with roots dating back to 1842, has sold millions of backhoe loaders globally. The 580 series alone has become one of the most recognized and widely used backhoe platforms in the world, with the ST variant tailored for international markets, particularly in Europe and Australia.
Unexpected Loader Drop Explained
A peculiar issue was observed on a newly acquired Case 580ST: when the front of the machine was lifted off the ground using the loader arms, everything functioned normally—until the backhoe hydraulic switch was activated. At that moment, the loader arms unexpectedly dropped, causing the front end to settle back onto the ground.
This behavior puzzled the operator, as the loader should remain in position regardless of backhoe engagement. The root cause was eventually traced to the activation of the ride control system.
Understanding Ride Control Functionality
Ride control is a hydraulic cushioning system designed to improve operator comfort and reduce material spillage during travel. It works by allowing the loader lift cylinders to float slightly, absorbing shocks from uneven terrain. When ride control is engaged, the loader arms are no longer hydraulically locked in place—they can move in response to external forces, including gravity.
In this case, activating the backhoe hydraulics automatically enabled ride control, which caused the loader arms to depress under the machine’s weight. This is a normal function, not a malfunction, but it can be confusing if the operator is unaware of the linkage between backhoe activation and ride control logic.
How to Disable Ride Control When Stationary
To prevent the loader from dropping when using the backhoe:
Best Practices for Dual-End Operation
When using both loader and backhoe functions:
The Case 580ST’s loader drop during backhoe activation is a direct result of ride control engagement—a feature designed for travel, not stationary work. Understanding how ride control interacts with hydraulic circuits is essential for safe and efficient operation. With proper switch management and awareness of system behavior, operators can avoid unexpected movements and maintain full control of both loader and backhoe functions. The 580ST remains a powerful and versatile machine when used with informed technique.

How to Disable Ride Control When Stationary
To prevent the loader from dropping when using the backhoe:
- Locate the ride control switch in the cab (often near the loader joystick or dashboard)
- Set it to the OFF position before engaging the backhoe hydraulics
- Alternatively, use the AUTO setting only when traveling, not during stationary digging operations
Best Practices for Dual-End Operation
When using both loader and backhoe functions:
- Always stabilize the machine with outriggers before engaging the backhoe
- Ensure ride control is off to maintain loader arm position
- Avoid lifting the front end unless necessary for leveling or trenching
- Monitor hydraulic pressures and flow rates to prevent system overload
