Used Post Digger Buying Guide
A used post digger can be a smart investment for landscaping, fencing, or construction projects—if you know how to choose the right machine. Because post diggers face heavy wear, shopping the secondary market requires extra care. This guide covers the essential angles buyers search for so you can make a confident, professional decision.
Why Consider a Used Post Digger?
- Budget efficiency: Quality new models are costly. A well-maintained used digger often delivers comparable performance at a fraction of the price.
- Immediate availability: Waiting for a new unit can delay tight schedules. Used equipment is often ready to work within days.
- Suitable for occasional use: If your projects are seasonal or low-volume, a used digger may deliver all the capability you require without the overhead of new-equipment financing.
Assessing Machine Condition
When evaluating a used post digger, inspect three core areas:
- Drill Assembly & Auger
- Check for bends, cracks, or excessive wear on the auger flights and cutting edge.
- Ensure the gearbox turns freely without grinding noises.
-
Look for oil leaks or gouges on the drive shaft that could indicate past overloads.
-
Mounting System
- For skid-steer or mini-excavator attachments, confirm pins, hoses, and quick couplers are intact.
- Ensure hydraulic hoses are not cracked, hard, or leaking.
-
If buying a standalone trailer-based digger, verify the hitch, jack, and tires are sound.
-
Operational History
- Ask for maintenance records: regular grease, oil changes, and belt/chain checks matter.
- Confirm total operating hours if the machine has an hour meter.
- Request the reason for sale—machines retired early are often the best buys.
Performance & Compatibility
- Gauge drilling capacity: Match the auger diameter and depth rating to typical post sizes (e.g., 4×4 posts vs. large trees).
- Power source: Confirm hydraulic flow requirements if integrating with your carrier. Overpowered carriers waste fuel; underpowered ones stall.
- Auxiliary equipment: Look for included extensions, pilot bits, and quick-change drives to save time on future jobs.
Safety & Documentation
- Ensure safety shields and guards are intact and not missing.
- Verify the serial number and model match the paperwork.
- For high-capacity diggers, inspect the emergency stop and warning labels.
Pricing Benchmarks
Use current pricing data from reputable dealers or auction platforms to establish a fair range. Consider:
- Age and brand reputation (e.g., Bobcat, Auger Torque, Digga).
- Recent repairs or replacement parts—these reduce the need for immediate investment.
- Included accessories. A unit with a new set of bits or quick-mount plate may justify a higher price.
Make the Purchase
- Negotiate based on observable defects you’re willing to address.
- If possible, test the digger on-site: operate the hydraulics, feel for responsiveness, and listen for abnormal vibrations.
- Ask if a service check can be performed before finalizing—used dealers sometimes offer minor tune-ups.
Acquiring a used post digger requires diligence, but the payoff is a tool that keeps projects moving without overshooting the budget. Keep these evaluation pillars in mind, and you’ll find a professional-grade attachment that feels like new.
