In 2018, I almost bought a used backhoe because it looked great in the photos. The owner said the hydraulics were fresh, the hours were low, and the service records were 'somewhere in the truck.' He never found them. I walked away, mostly because the price felt too high. Another buyer jumped on it a week later. The machine cracked a final drive within a few days. That moment turned me into the guy who documents every mistake before handing the checklist to the next person.
This article compares the two ways most contractors buy used equipment: auction vs. dealer. I've used both. I own a Westinghouse generator bought at auction, an engine hoist picked up from a closing shop, and a copy of the Schwing P88 concrete pump manual. I've also made enough expensive mistakes to know that the machine itself is only half the story.
So here's the framework I use now. Compare three things: history, parts support, and total cost. If the numbers work in all three, you're doing better than most people.
1. History and inspection: dealer vs. auction
An auction listing gives you a few photos, a start-up video, and a 'buyer beware' stamp. A dealer can usually hand you an inspection report and a maintenance history. That difference matters more for a complex machine—like a Schwing concrete pump—than for a simple attachment.
My worst mistake happened in 2021. I assumed a digital hour meter was correct because the pump body was clean. Didn't verify against the service history. It turned out the meter had been replaced after an engine rebuild, and the 'low hour' pump was actually running on thousands more hours than the display showed. Two months later, a cracked cylinder head cost me about $2,800 and a month of downtime.
If you're looking at an older concrete pump, do this before you bid: get the Schwing P88 concrete pump manual and match the serial plate to the parts diagrams. The manual shows you which hydraulic pump, engine, and rock valve were original. It also gives torque specs so you're not guessing. A dealer who sells Schwing equipment will usually help you pull that information. An auction seller won't.
Conclusion: the dealer wins on history. The auction can work if you take your own inspector—or get good at asking for service logs before the hammer drops.
2. Parts, manuals, and support: dealer vs. auction
You're not just buying a machine. You're buying the ability to keep it running.
'Parts are only as good as the diagram you used to order them.'
I wrote that rule after a communication failure that still makes me grind my teeth. I called the parts counter and said, 'We need standard wear plates for the P88.' They heard, 'Whatever you have in stock.' The plates were close, but not right. We didn't catch it until the pump was split open on the shop floor. Since then, I take the old part with me, use the manual illustration, and read the serial number out loud.
Schwing parts are usually available. I check the Schwing America parts portal from time to time, just to be safe. As of March 2025, you can still look up most legacy components by serial number. But availability doesn't mean you'll order the right revision on the first try.
The same logic applies to the tools you'll need after the purchase. I always budget for an engine hoist when the machine has a mid-size diesel in it. An engine hoist is the difference between swapping a fuel pump in one afternoon and paying a technician for a full day. A Westinghouse generator (the one I bought used for $500) covers me when the job site or my own driveway doesn't have shore power. Those are auction-worthy buys because they're simple. A hydraulic pump is not simple.
Conclusion: the dealer wins on support. If you buy at auction, go to the parts counter before you pay. (Actually, embarrassingly, I've done it after—don't be like me.)
3. Total cost: dealer vs. auction
The number on the auction screen isn't the real price. Add the buyer's premium, transport, travel, repairs, consumables, and the billable hours you lose while the machine sits in the shop.
In September 2023, I watched a contractor pay $11,500 for a backhoe at auction. Then he paid $800 to ship it, $1,200 for tires, $450 for a control valve rebuild kit, and a week of shop time before he trusted it. A similar machine from a dealer was listed at $16,900—serviced and ready to work. I'm not 100% sure he ever added that up. If you ask me, the dealer machine would've been the cheaper option by the time it landed on the job.
For a Schwing P88, the same math applies. A low auction price can be a steal if the pump was working when retired and you have the manual. It can be a trap if the concrete rock valve (the part that switches flow from one pump cylinder to the other), wear plates, and hydraulic hoses are at the end of their life. Those are normal replacement items, but they add up fast.
Conclusion: the auction can win on initial price. The dealer usually wins on total cost when you count your time and downtime.
Excavator vs backhoe: which digging machine do you need?
This is the question that comes up after people stop renting. It's also the wrong first question. Ask what work you'll do every week before you ask what deal is in front of you.
An excavator will dig deeper, lift more at the bucket, swing 360 degrees, and work in tighter spaces. It's a specialist: foundations, utility trenches, basements. A backhoe loader (what most people mean by 'backhoe') is a generalist: it can dig a little, load a little, carry pallets, and drive on the road. It will never match a true excavator for pure digging power, but it replaces three machines on small mixed jobs.
If you do residential foundations or utilities, buy the excavator. If you run a maintenance crew, landscaping business, or small farm crew, the backhoe loader makes more sense. Just don't buy either because the auction price is tempting. The hoses, cylinders, and tracks don't care what you paid.
And if your actual bottleneck is placing concrete—not digging holes—the right move might be a Schwing pump, not a digging machine. But that's a separate checklist.
What I'd do differently (the checklist version)
If I were buying for myself today:
- Buy simple tools at auction. My Westinghouse generator and my engine hoist were both auction finds. I'd do it again.
- Buy complex machines from a dealer or an owner with a real maintenance log. 'One-owner, clean' is not a maintenance log.
- Get the manual before the machine. For an older Schwing pump, that means the Schwing P88 concrete pump manual and a serial number to read over the phone.
One more thing. I've learned to treat every equipment purchase as a relationship, not a transaction. If you buy from a dealer who answers the phone a month later, that phone call is worth more than the 10% you saved at the auction. If you ask me, that's the real difference.
