The John Deere 320E Skid Steer is a powerful and versatile machine used in various construction, landscaping, and agricultural applications. Known for its compact size and impressive lifting capabilities, the 320E is ideal for maneuvering in tight spaces and performing heavy-duty tasks such as digging, grading, and material handling. However, to achieve the best performance, operators often need to adjust certain settings on the skid steer, including its lift arms, hydraulic system, and operator controls.
This article discusses how to adjust the John Deere 320E Skid Steer to maximize its efficiency, ensure safety, and extend its lifespan. We will explore the key adjustment areas, provide troubleshooting advice, and offer general maintenance tips to keep the machine running at its best.
Key Features of the John Deere 320E Skid Steer
Before diving into adjustments, it's important to understand the key specifications of the 320E skid steer. This model is equipped with a range of powerful features that make it a popular choice in the market.

• Engine Power: The 320E is powered by a 74.3 horsepower (55 kW) diesel engine, providing excellent power for a variety of attachments and heavy tasks.
  
• Operating Capacity: With a rated operating capacity of 2,000 lbs (907 kg), the 320E can handle a wide range of materials and tools, making it suitable for both light and heavy-duty operations.
  
• Hydraulic Flow: The machine has a high-flow hydraulic system, delivering up to 23.6 gpm (89.3 L/min), which is crucial for operating larger attachments like augers, trenchers, and planers.
  
• Dimensions: With a compact design, the 320E has a width of 60.2 inches (1,528 mm), allowing it to easily navigate narrow spaces while maintaining stability.
  

Now that we know the specifications, let's focus on the adjustment areas that will enhance its operation.
Adjusting the Lift Arms for Better Performance
The lift arms on a skid steer play a critical role in lifting and lowering loads. If the lift arms are not adjusted properly, the machine can experience issues with lifting capacity, stability, and overall performance. The John Deere 320E allows for adjustment of the lift arms to optimize lifting and handling tasks.

• Lift Arm Calibration: If the lift arms are not reaching their full height or are uneven, the hydraulic system may require calibration. This can be done by adjusting the lift arm speed and height settings in the machine’s control panel. Calibration ensures that the lift arms operate smoothly and at the correct height for specific tasks.
  
• Hydraulic Pressure Adjustment: The hydraulic system of the 320E is designed to provide optimal lifting force. If you notice that the machine is struggling to lift heavy loads, check the hydraulic fluid levels and inspect for any leaks. If the hydraulic pressure is too low, it may need to be increased, which typically involves adjusting the pressure relief valve. Consult the operator’s manual for the correct procedure for hydraulic adjustments.
  

Fine-Tuning the Operator Controls
The operator controls of the John Deere 320E are highly customizable to accommodate different user preferences and operational needs. Adjusting these controls can improve comfort, increase productivity, and prevent strain on the operator during extended use.

• Joystick Sensitivity: The 320E uses joystick controls to operate the machine's movement, lift, and tilt functions. If the joystick is too sensitive or not responsive enough, it can be adjusted to fit the operator’s preferences. Adjusting the joystick’s response time and sensitivity can help make the machine easier to operate and provide smoother handling, especially when working in tight areas.
  
• Seat Positioning: To ensure maximum comfort and control, adjust the seat of the skid steer. The seat should be positioned at a comfortable height with a clear line of sight to the controls and the work area. This not only improves operator comfort but also enhances safety, as it allows for better visibility of the job site.
  

Maintaining the Hydraulic System
A skid steer's hydraulic system is essential for the smooth operation of various functions, including lifting, tilting, and operating attachments. Proper maintenance of the hydraulic system is vital for the performance and longevity of the 320E.

• Regular Fluid Changes: Hydraulic fluid should be changed at regular intervals according to the manufacturer’s recommendations. Using the right type of hydraulic fluid and maintaining proper fluid levels helps ensure that the machine operates efficiently, reducing wear on the system and preventing overheating.
  
• Inspecting Hydraulic Hoses: Over time, hydraulic hoses may develop leaks or become worn. Regularly inspect all hoses for signs of damage or leaks, and replace any damaged hoses immediately to avoid fluid loss and potential system failure.
  
• Air Bleeding: Sometimes, air can enter the hydraulic system, leading to erratic operation or reduced lifting capacity. If you notice abnormal behavior from the lift arms or attachments, it might be time to bleed the air from the system. This process is typically done using the machine’s hydraulic pump and requires careful attention to the hydraulic lines.
  

Troubleshooting Common Problems
Despite its robust design, the John Deere 320E skid steer may encounter common operational issues that require troubleshooting.
1. Slow or Uneven Lift
If the lift arms are slow or uneven, this could be due to low hydraulic fluid levels, a malfunctioning hydraulic pump, or worn-out lift cylinders. The first step is to check the hydraulic fluid and top it up if needed. If the issue persists, inspect the hydraulic components for leaks or damage.
2. Reduced Power or Lag in Controls
A reduction in power or delayed response from the controls can be caused by several factors, including clogged air filters, low engine power, or a dirty fuel filter. Regularly clean or replace filters, check the engine for performance issues, and ensure that the machine is running at its full potential.
3. Uneven Tire Wear
Uneven tire wear can occur if the machine is not properly balanced or if the tires are not inflated to the correct pressure. Check the tire pressure regularly and inspect the alignment of the wheels. Uneven wear may also indicate the need for adjustments in the lift arms or suspension.
Conclusion
The John Deere 320E Skid Steer is a reliable and efficient machine that can tackle a variety of tasks with ease. By adjusting key settings such as lift arms, hydraulic pressure, and operator controls, operators can improve performance, increase comfort, and extend the lifespan of the equipment. Regular maintenance, including fluid changes, hydraulic inspections, and tire checks, will ensure the machine remains in top condition.
With proper care and adjustments, the John Deere 320E can continue to provide excellent performance in construction, landscaping, and other industries for years to come. Always refer to the operator's manual for specific maintenance schedules and adjustments, and if issues persist, consult a trained technician to keep your machine running smoothly.
