Start by answering these three critical questions:
"What is my primary task?" – Define the Core Work
Is it deep excavation, general material loading, or fine grading?
Are you working in heavy-duty mining or delicate municipal projects?
Your core task directly determines whether you need an excavator, wheel loader, bulldozer, or another machine.
"What are my site conditions?" – Understand the Constraints
Space Limits: Are you in tight city streets or an open field? This dictates the machine's size and maneuverability (e.g., a zero-tail-swing excavator vs. a standard model).
Ground Conditions: Is the terrain solid rock, common soil, or soft sand? This determines if you need tracks (for better stability and lower ground pressure) or wheels (for greater mobility and less surface damage).
Attachments: Will you need a hydraulic breaker, ripper, or shear? If so, ensure the machine has the auxiliary hydraulics and a quick coupler to support them.
"How much machine do I need?" – Find the Right Size
Choosing an oversized machine wastes money and complicates transport. An undersized one will be inefficient and delay your project.
Based on your average project scale and timeline, select a model with the appropriate power and capacity. For instance, a 20-ton excavator is often a cost-effective choice for general farming and small construction projects.
Your budget is your reality check. A smart budget is much more than just the sticker price.
The Purchase Price: Your Starting Point
Research the market price for your target machine (e.g., "Used Caterpillar 320D") and set a firm maximum bid.
The Hidden Costs: The Most Commonly Overlooked Pitfalls
Immediate Service Cost: After purchase, we strongly recommend a full initial service (engine oil, hydraulic oil, filters). Reserve at least 3-5% of the purchase price for this "health check" fund.
Repair Reserve Fund: Used equipment can be unpredictable. Always set aside a contingency fund for potential repairs.
