5 Tips for Buying a Used Mini Excavator

Excavators are indispensable tools in the realms of construction and landscaping. However, the idea of purchasing a used excavator can often be intimidating. To ensure that you’re not only getting value for your money but also a reliable machine, here are five things every buyer should scrutinize.

Undercarriage Inspection

The undercarriage is a significant contributor to an excavator’s overall maintenance costs. When inspecting a used excavator:

  • Tracks: Check for signs of excessive wear or damage
  • Rollers, Idlers and Sprockets: These should be examined for any wear and tear. Any signs of a deteriorating undercarriage can lead to substantial replacement costs in the future.

Hydraulic System Check

The hydraulic system is essentially the lifeblood of an excavator. Here’s what to keep an eye on:

  • Leaks: Especially around the cylinders and hoses.
  • Functionality: Test the hydraulic functions. Any lack of smoothness or delays could hint at potential problems.

Attachment Compatibility

An excavator’s utility goes beyond its bucket. The excavator’s versatility in terms of compatible attachments is as crucial as the bucket’s condition. Here’s what you should consider:

  • Quick Coupler System: Is it universal or brand-specific? This determines the variety of attachments you can pair with the machine.
  • Pins and Bushings: Assess these conditions on the arm and attachment points. They are crucial for efficient attachment swaps and safe operation.

Engine and Fluids

The engine’s health is paramount to the longevity of this machine. Here’s your checklist:

  • Sounds: Start the engine. Are there any odd noises?
  • Exhaust: Look out for excessive smoke.
  • Fluid Levels and Quality: Inspect the engine oil, hydraulic fluid, and coolant. Discoloured or dirty fluids might suggest previous neglect.

Operate and Observe

Before sealing the deal, always test the machine:

  • Rotation: The excavator should rotate smoothly.
  • Responsiveness: Check the boom, stick, and bucket’s reactions.
  • Cabin Electronics: Ensure that gauges and monitors are in working order.

Purchasing a used excavator is a considerable investment. With these top 5 tips in your arsenal, you’re now equipped to make an informed decision, ensuring that your chosen machine is cost-effective and task-ready.
