How to Inspect a Used Excavator Before You Buy: 7 Key Checks

Buying used excavators is a smart investment — if you know what to look for. A proper inspection can help you avoid expensive surprises and ensure your heavy equipment works hard from day one. Here are 7 key checks before making the purchase.

1. Visual Exterior Inspection

Look for signs of damage, welding, rust, or heavy dents. The body tells a story — and you want it to be a good one.

2. Check Hydraulic Components

Inspect hoses, cylinders, and connectors for leaks or excessive wear. Hydraulic issues are among the costliest to fix.

3. Start the Engine

Listen for irregular sounds, check for smoke color, and assess how smoothly the engine runs. A cold start can reveal a lot.

4. Operate All Functions

Test arm, boom, and bucket controls. Watch for delayed or jerky movement, which may signal deeper issues.

5. Undercarriage Inspection

The undercarriage takes the most abuse. Look at track tension, rollers, and sprockets. Excessive wear may require replacement.

6. Review Operating Hours

Compare the hour meter to the condition of the machine. A clean 2,000-hour excavator should not look like it’s done 10,000.

7. Request Service Records

A well-maintained used excavator will have consistent service logs. If records are missing, ask why — and proceed carefully.

Conclusion

Doing your homework upfront pays off. A thorough inspection is your first layer of protection when investing in heavy equipment.
