Judging Machine Condition From Photographs When You Cannot View
Cover: Freepik via Magnific (see credits.csv)
Most machinery bought at online auction is bought from a set of photographs and a written description. That is workable if you read a listing the way a buyer should: photographs tell you about wear and tear and about consistency, and they cannot tell you about engine internals, hydraulic performance or anything hidden under dirt. The discipline is to separate what you can see, what you can ask, and what you must simply price as unknown. Lot details come from the vendor and we do not inspect the machinery, so every judgement here is yours to make.
Why is so much machinery bought without a physical inspection?
Because timed online auctions are national and the machines are not. A lot may be four hundred miles away, on a working site, in a sale that closes before a trip would be worth making. Buyers who do this well are not gambling: they have a repeatable way of reading a listing and a habit of pricing what they cannot see.
It is worth being clear about what a listing is. Everything in it comes from the vendor's own details and photographs. We do not see the stock, we do not inspect the machinery, and we do not warrant its condition, hours, description, title or fitness for purpose. Universal Auctions Group Ltd acts solely as auctioneer and agent for the vendor and is not a party to the contract of sale, which is formed between the vendor and the successful bidder. Lots are sold as seen, where lying, with descriptions and images provided for guidance, and buyers must carry out their own inspection and due diligence.
Viewing is available strictly by prior appointment and is strongly recommended. Any testing must be agreed in advance and is subject to the seller's site and safety requirements. Where a viewing is not practical, what follows is how to get the most out of what you can see. This applies across our plant and machinery auctions, and sits alongside the pricing side of the job in valuing used plant and machinery before you bid.
What can a photograph actually tell you?
More than most buyers use. A set of photographs is evidence about wear, about how the machine was looked after, and about whether the story the listing tells is consistent. What it is not is evidence about mechanical function. Treat every visual signal as a question to ask rather than a conclusion to act on.
- Ram chrome and seals. What it suggests: Scoring, pitting or weeping at the gland points to wear or damage. What it does not prove: Whether the hydraulic system holds pressure under load.
- Pins, bushes and linkages. What it suggests: Ovalling, grease absence and daylight in a joint suggest wear. What it does not prove: How much life is left, which needs measuring.
- Tracks, tyres, drums or cutting edges. What it suggests: Remaining life on the parts that wear predictably. What it does not prove: Condition of the drive components behind them.
- Fluid marks and clean patches. What it suggests: Recent leaks, or recent cleaning of an area that leaked. What it does not prove: The source or seriousness of the leak.
- Cab wear: seat, pedals, controls. What it suggests: A cross-check against the stated hours. What it does not prove: The hour reading itself, which is unverified unless the listing confirms it.
- Paint, panel gaps and weld repairs. What it suggests: Previous damage and the standard of the repair. What it does not prove: Whether the underlying structure is sound.
- Consistency across shots. What it suggests: Whether the machine in the detail shots is the machine in the wide shot. What it does not prove: Anything about what is not photographed at all.
How do you read the background as well as the machine?
The setting is free information about the listing, not about the machine. A machine photographed on clean hardstanding in good light, from several angles, gives you more to work with than one photographed in a corner of a field in the rain from two angles. Neither tells you anything about condition or about how the machine has been looked after. What they tell you is how much weight the photographs themselves can carry.
- Count the angles. A thorough set covers all four sides, the working end, the cab, the plate and the meter. Where the set is less complete, that is simply less information, and the gaps are worth asking about rather than reading anything into.
- Look at what is around it. Other machines in the frame are context for the listing, though they say nothing definite about the lot you are bidding on.
- Check the ground. A machine sunk into soft ground is a collection problem before it is a condition problem.
- Look for the things nobody stages. Puddles under a machine, a battery on the floor, a panel resting against a wheel.
- Note the light and the season. Photographs taken months before a sale may not reflect where the machine is now or how long it has stood.
What about plates, meters and dashboard screens?
They are the highest-value images in any listing, and the ones most often missing. A legible serial or PIN plate lets you check the machine's identity and specification against the description. A photograph of the hour meter gives you a reading to work with, though hour readings are unverified unless the listing expressly confirms them.
A word of caution on dashboards. A warning light visible in a photograph is a reason to ask a question, not proof of a fault: lights show during a normal start sequence, and a machine photographed at the moment of ignition will display several. Equally, a dashboard photographed with the machine switched off tells you nothing at all. Ask what the seller can confirm, and take the answer as information rather than a warranty.
If the plate is not photographed, ask for it. A serial or PIN plate that has been ground off, over-painted or does not match the paperwork is a reason to stop rather than a detail to resolve later, and that is as true of a machine you are viewing as one you are not.
What can photographs never show?
Everything that only reveals itself under load or under a cover. Engine internals, injector and turbo condition, transmission behaviour, hydraulic performance, electrical faults, ECU history, and structural cracks hidden by dirt or fresh paint. These are not gaps you can close with more images, so they have to be priced instead.
This is the part that separates a disciplined buyer from an optimistic one. You are not trying to eliminate uncertainty, which is not possible on a machine you have not run. You are trying to put a number on it and take that number out of your bid.
How do you turn uncertainty into a number?
Set a contingency for what you cannot see and deduct it before you calculate your maximum bid, not afterwards. The size of the allowance depends on how complete the listing is, what the machine is, and how expensive its worst realistic failure would be. A hydraulic breaker and a lighting tower do not deserve the same allowance.
The arithmetic runs in this order. Start with what you can afford delivered. Take out transport. Take out your condition allowance. Then divide what remains by 1.15 to strip an illustrative 15% premium, before VAT is applied according to the lot's own treatment. If you cannot recover VAT it belongs inside the same budget, which lowers the maximum bid again. Percentage charges are divided out rather than subtracted as flat sums, because the two methods give different answers. The rates that apply to a lot are stated on its Additional Fees tab.
Setting the allowance at zero is a decision, not a default. It says you believe the photographs and the description cover the risk, which is sometimes reasonable on a simple machine with a full set of images and sometimes wishful on a complex one with four.
What should you ask before you bid?
Specific, answerable questions, sent early enough to get a reply before the lot closes. Vague questions produce vague answers. The best ones ask for an image or a fact rather than an opinion about condition.
- Ask for the missing photographs. Serial plate, hour meter, the side that is not shown, the underside of the boom, the inside of the cab.
- Ask what is included. Attachments, buckets, keys, spare wheels, manuals, chargers, cables. Assume nothing that is not written down.
- Ask what the vendor can confirm about running. Take the answer as information from the vendor, since we do not test machinery.
- Ask about access and loading. Where the machine sits, whether it can be moved, who is loading, what ground conditions are like.
- Ask about paperwork. What documents come with the lot, and what the title information for that lot says.
- Arrange a viewing where the value justifies it. Strictly by prior appointment, with any testing agreed in advance.
Send the questions in one message rather than five, and send them before the last day of the sale. A lot can be withdrawn, suspended or have its end time modified under the auction terms, and a bid below reserve becomes a provisional bid valid for 24 hours after the sale closes, so leave yourself time.
Common mistakes to avoid
- Treating a clean machine as a good machine. A pressure washer is cheaper than a hydraulic overhaul.
- Reading a warning light as a fault. It is a question to ask, not a conclusion.
- Taking the hour meter as history. Readings are unverified unless the listing expressly confirms them.
- Assuming the photographs are recent. Ask when they were taken and where the machine is now.
- Ignoring what is absent. An angle that is not in the set is information you do not have, so ask for it rather than assume it either way.
- Carrying no contingency. On a machine you have not run, a zero allowance is a bet rather than a bid.
- Asking questions on the last afternoon. Give the seller time to answer before the lot closes.

Frequently asked questions
Can you really buy machinery without seeing it?
A great deal of machinery is bought this way, and it works when the buyer reads a listing methodically and prices the uncertainty rather than ignoring it. Everything in a listing comes from the vendor's own details and photographs. We do not inspect the machinery and do not warrant its condition, hours, description, title or fitness for purpose, and lots are sold as seen, where lying, with descriptions and images provided for guidance. Viewing is available strictly by prior appointment and is strongly recommended where the value justifies the trip.
What should I look for in the photographs of a used excavator?
Detail rather than the wide shot. Ram chrome and seals for scoring, pitting or weeping. Pins, bushes and linkages for ovalling and missing grease. Tracks, tyres or cutting edges for remaining life. Fluid marks on the ground, and clean patches where an area may have been washed. Cab wear on the seat, pedals and controls as a cross-check against the stated hours. Paint, panel gaps and weld repairs for previous damage. Then check the shots are consistent with each other.
Does a warning light in a listing photograph mean the machine is faulty?
No. It is a reason to ask a question rather than a conclusion. Warning lights illuminate during a normal start sequence, so a machine photographed at the moment of ignition will show several. A dashboard photographed with the machine switched off tells you nothing at all. Ask what the vendor can confirm about the machine running, and treat the answer as information from the vendor rather than a warranty, since we do not test machinery.
What can photographs never tell me?
Anything that only shows itself under load or under a cover: engine internals, injector and turbo condition, transmission behaviour, hydraulic performance, electrical faults, ECU history, and structural cracks hidden by dirt or fresh paint. More images will not close those gaps, which is why they have to be priced instead. Decide what the worst realistic failure on that machine would cost and set your allowance accordingly.
How big should my condition allowance be?
It is a judgement about the individual lot, based on how complete the listing is, what the machine is, and how expensive its worst realistic failure would be. As an illustration of the effect, on a £15,000 delivered budget with £450 of transport, a maximum hammer bid works out at roughly £12,652 with no allowance, £11,387 with an allowance of 10% of the money left after transport, and £10,122 at 20%, once an illustrative 15% premium is divided out. Setting the allowance at zero is a decision, not a default.
What questions should I send before bidding?
Specific ones that ask for a fact or an image rather than an opinion. Ask for the photographs that are missing: serial plate, hour meter, the side not shown, the underside of the boom, the cab interior. Ask what is included, since attachments, keys, manuals and cables are separate unless stated. Ask what the vendor can confirm about the machine running. Ask about access, loading and ground conditions. Send them in one message and well before the last afternoon of the sale.
Is a clean machine a good machine?
Not necessarily, and it is one of the most common assumptions worth resisting. A pressure washer costs far less than a hydraulic overhaul, and a recently cleaned area can be where a leak was. Cleanliness tells you something about presentation and possibly about care, but it is not evidence of mechanical condition. Judge the machine on wear detail, consistency across the images, and what the vendor can confirm.
