John Deere, one of the leading manufacturers of agricultural and construction machinery, is known for producing robust and high-performance equipment, including skid steers like the John Deere 328D. One of the notable features in some John Deere skid steers, such as the 328D, is the ride control system, designed to improve operator comfort and enhance machine performance. This article delves into how the ride control system works, its benefits, and troubleshooting common issues that operators may encounter.
What is Ride Control?
Ride control is a feature designed to reduce the impact of rough terrain on the operator while driving the skid steer. It accomplishes this by using hydraulic cushioning to soften the ride, especially when traveling over uneven surfaces or obstacles. Ride control works by using a system of accumulators and valves that dampen the vibrations and sudden jolts that would otherwise be transmitted to the operator through the seat and control system.
In a skid steer like the John Deere 328D, ride control helps in various applications where the loader is moving quickly across rough ground, such as grading, material handling, or moving between construction sites. The smooth, cushioned ride not only helps reduce operator fatigue but also minimizes wear and tear on the machine’s components, particularly the hydraulic system.
Components of the Ride Control System
The ride control system in the John Deere 328D is composed of several key components that work together to deliver a smoother ride:
Ride control systems provide several key benefits for operators, especially when working in tough environments:
While the ride control system on the John Deere 328D is designed to be reliable, it can sometimes experience issues that affect its performance. Common problems include the system not engaging, poor performance, or total failure. Here’s a step-by-step guide to troubleshooting these problems:
1. System Not Engaging
If the ride control system is not engaging as expected, it may be due to a malfunctioning control valve or hydraulic fluid level issues. Here’s what to check:
If the ride control system is engaging, but you notice a rougher ride than usual or inconsistent performance, the following issues could be at play:
Sometimes, operators may experience issues with the ride control system not disengaging when needed. This can be problematic, especially when the machine is operating at lower speeds or on level ground. Here’s how to address this issue:
To ensure the longevity and reliability of the ride control system on the John Deere 328D, operators should follow these maintenance best practices:

Components of the Ride Control System
The ride control system in the John Deere 328D is composed of several key components that work together to deliver a smoother ride:
- Hydraulic Accumulators: These are key components that store hydraulic fluid under pressure. When the machine encounters a bump or uneven surface, the accumulator absorbs the shock and reduces the impact on the rest of the system.
- Ride Control Valve: This valve controls the flow of hydraulic fluid between the accumulator and the hydraulic circuit, ensuring that the ride control system activates only when needed.
- Control Switch: The system typically includes a switch inside the cabin that allows the operator to activate or deactivate the ride control function. Some models may automatically engage the system when certain conditions, like speed, are met.
- Hydraulic Lines: These are responsible for transmitting the hydraulic fluid throughout the ride control system. Over time, they can wear out or develop leaks, affecting the system’s performance.
Ride control systems provide several key benefits for operators, especially when working in tough environments:
- Reduced Operator Fatigue: By smoothing out the ride, operators are less likely to experience the physical strain of continuous jolts, bumps, and vibrations. This allows them to work longer hours with less discomfort.
- Increased Productivity: A smoother ride enables the operator to maintain better control of the machine, particularly when moving quickly or handling sensitive tasks like grading or transporting materials over uneven ground.
- Enhanced Machine Longevity: By reducing the impact on the loader’s components, ride control helps to extend the life of critical parts, including the hydraulic system, loader arms, and the tires.
- Better Load Handling: For tasks like carrying materials in the bucket, a smoother ride means that the load remains more stable, reducing the risk of spillage or shifting. This is particularly useful in applications like landscaping, waste management, and construction.
While the ride control system on the John Deere 328D is designed to be reliable, it can sometimes experience issues that affect its performance. Common problems include the system not engaging, poor performance, or total failure. Here’s a step-by-step guide to troubleshooting these problems:
1. System Not Engaging
If the ride control system is not engaging as expected, it may be due to a malfunctioning control valve or hydraulic fluid level issues. Here’s what to check:
- Check the Control Switch: Ensure that the ride control switch inside the cabin is functioning properly. Sometimes, the switch can become damaged or disconnected, preventing the system from turning on. Make sure the switch is in the “on” position, and test it for proper electrical connection.
- Inspect the Hydraulic Fluid Level: Low hydraulic fluid levels can cause the system to malfunction. If the fluid is low, it can lead to an under-pressurized system that may prevent the ride control from working effectively. Top up the hydraulic fluid with the recommended type as specified in the machine’s user manual.
- Check the Ride Control Valve: The ride control valve regulates the hydraulic fluid’s flow and pressure. If the valve is stuck or clogged, it may not engage properly. Inspect the valve for damage or obstructions, and ensure that it is properly lubricated.
If the ride control system is engaging, but you notice a rougher ride than usual or inconsistent performance, the following issues could be at play:
- Faulty Hydraulic Accumulators: The accumulators are the primary components responsible for absorbing shocks and smoothing out the ride. Over time, these can wear out or leak, reducing their effectiveness. If the accumulators are faulty, they may need to be replaced.
- Hydraulic Line Leaks: Leaking hydraulic lines can cause a loss of fluid pressure, affecting the ride control system’s performance. Inspect the hydraulic lines for any visible signs of damage, such as cracks, punctures, or loose fittings. If leaks are found, replace the affected parts immediately.
- Clogged or Dirty Filters: The ride control system relies on clean hydraulic fluid to function properly. Clogged or dirty filters can cause restricted fluid flow, which in turn can affect the performance of the ride control system. Regularly clean or replace the filters to ensure smooth operation.
Sometimes, operators may experience issues with the ride control system not disengaging when needed. This can be problematic, especially when the machine is operating at lower speeds or on level ground. Here’s how to address this issue:
- Check the Switch and Wiring: A malfunctioning switch or wiring could cause the system to remain engaged even when turned off. Inspect the wiring to ensure there are no short circuits or damaged connections.
- Check for System Blockages: If there is a blockage in the ride control valve or hydraulic lines, the system may not disengage properly. Clean or repair any blockages that may be causing the issue.
To ensure the longevity and reliability of the ride control system on the John Deere 328D, operators should follow these maintenance best practices:
- Regular Fluid Checks: Always check the hydraulic fluid levels regularly and top them up as needed. Using the correct type of fluid is critical to maintaining the system’s performance.
- Inspect the Accumulators: Periodically inspect the accumulators for any signs of wear, damage, or leaks. These components are vital for effective ride control, so replacing them when necessary is essential.
- Clean and Replace Filters: Keep the hydraulic filters clean and replace them at the manufacturer-recommended intervals to avoid blockages and system failures.
- Inspect Hydraulic Lines and Connections: Routinely check the hydraulic lines and connections for leaks, cracks, or damage. Addressing any issues early can prevent larger, more costly problems down the road.
