Key Considerations When Buying a Used John Deere 320 Skid Steer
When buying a used skid steer, it's crucial to evaluate several factors to ensure the machine is in good condition and that you're getting your money’s worth.
1. Engine and Transmission Condition
The engine is the heart of any machine, and the John Deere 320 is no exception. When inspecting the engine, check for:

• Oil levels and quality: Look for clear oil, and ensure that the oil levels are consistent. If the oil is dark or has a burnt smell, it may indicate engine wear or overheating.
  
• Leaks: Check for oil or coolant leaks around the engine. Leaks can lead to expensive repairs down the line.
  
• Exhaust system: Inspect the exhaust for unusual smoke, which could signal engine problems.
  
• Start-up issues: When starting the machine, listen for smooth operation. Any misfires or rough starts could suggest an underlying problem with the fuel system or engine components.
  

Also, check the transmission and hydrostatic drive system, as issues here can lead to costly repairs. Look for jerky movements or sluggishness in forward/reverse motion.
2. Undercarriage and Tires
The undercarriage and tires are vital to the skid steer’s performance and longevity.

• Tires: Examine the condition of the tires. Worn or bald tires can affect traction and require early replacement, adding to the overall cost of ownership. Ensure that all tires are evenly worn, as uneven wear can indicate alignment issues or improper weight distribution.
  
• Track system (if applicable): For track machines, inspect the tracks for cracks, excessive wear, or damage. A worn-out track system can be expensive to replace.
  
• Rollers and Idlers: Check the rollers and idlers for wear and proper alignment. Worn-out or misaligned rollers can lead to further damage to the undercarriage and reduce the overall performance of the skid steer.
  

3. Hydraulic System
The hydraulic system is responsible for operating the loader arm, bucket, and any attachments you might use. Check the following:

• Hydraulic fluid levels: Ensure the hydraulic fluid is at the proper levels. Low fluid levels can cause poor performance or damage to the system.
  
• Leaks: Look for any hydraulic fluid leaks around the hoses, cylinders, and pumps. Leaks are a sign of wear and could mean that you need to replace seals or other parts soon.
  
• Functionality: Test the hydraulic system by operating the arms and bucket. Listen for any unusual sounds such as grinding or high-pitched noises, which could indicate hydraulic issues.
  

4. Structural Integrity and Frame
The structural integrity of the frame and boom is essential to the skid steer's ability to perform heavy tasks safely. Inspect the frame for:

• Cracks: Look for any cracks in the frame, particularly around high-stress areas like the joints and mounting points.
  
• Welds: Examine the welds for signs of poor repair or cracks. Poor welds can compromise the machine's strength.
  
• Signs of previous repairs: Ask for any maintenance records or repair history. Machines that have had significant frame repairs may not be as reliable as those with a solid structure.
  

5. Electrical System
Check the electrical system to ensure the skid steer’s lights, controls, and other systems are functioning properly:

• Battery: Ensure the battery is in good condition, holding a charge, and free of corrosion.
  
• Lights and Indicators: Test the lights, gauges, and warning lights on the dashboard. A malfunctioning electrical system can be costly to repair.
  
• Wiring: Check for any frayed or exposed wires that could lead to short circuits or other electrical issues.
  

6. Operator’s Cabin and Comfort
The comfort and usability of the cabin play a significant role in how efficiently and safely you can operate the skid steer. Check for:

• Seat condition: Ensure the seat is in good condition, without excessive wear or tears.
  
• Control functionality: Test all the controls (joysticks, pedals, etc.) for smooth and responsive movement.
  
• Cab cleanliness: A well-maintained and clean cab usually indicates that the machine was taken care of. Excessive dirt or debris can point to poor maintenance practices.
  

What to Expect from the John Deere 320 Skid Steer
The John Deere 320 skid steer, when properly maintained, is capable of delivering excellent performance in a variety of tasks. Typical applications include:

• Construction: Digging, grading, lifting heavy materials.
  
• Landscaping: Clearing debris, moving soil, and using specialized attachments for specific tasks like trenching or auguring.
  
• Snow Removal: With the right attachments, the 320 can efficiently clear snow in both residential and commercial settings.
  

While it's not the largest skid steer in John Deere’s lineup, the 320 provides ample power for medium-duty tasks. Its compact size makes it ideal for work in tight spaces, such as in landscaping projects, small construction sites, or urban environments.
Common Issues with the John Deere 320 Skid Steer
While the John Deere 320 is generally reliable, some issues may arise in used models:

1. Hydraulic pump failure: The hydraulic pump is prone to wear over time, especially if the fluid is not regularly changed or maintained.
   
2. Undercarriage wear: As with any skid steer, the undercarriage can wear down depending on the usage and environment, especially in rough or rocky terrains.
   
3. Electrical gremlins: Electrical issues, while not common, may arise, particularly in older models.
   

Final Thoughts: Is the John Deere 320 Right for You?
The John Deere 320 skid steer is an excellent option for anyone in need of a reliable, versatile, and compact machine for medium-duty work. However, when buying a used model, it is essential to carefully inspect the machine for wear and tear, focusing on critical components like the engine, hydraulic system, undercarriage, and frame.
By following this comprehensive guide, you can make a more informed decision and ensure that you purchase a John Deere 320 that will provide excellent value for your business or personal projects.
