Outdoor power equipment.
A catalog read across the powered-equipment range of a manufacturer's own storefront — chainsaws, blowers, trimmers and brushcutters, where the specification table is the product, and some of its numbers cannot be true.
This is a real EKOM catalog analysis, with the client's identity removed. The client is a manufacturer of outdoor power equipment, selling direct to professionals and homeowners from its own US storefront. EKOM read the complete powered-equipment range from the structured data the storefront embeds in its own product pages, and flagged 38 items. 30 are reported here as actionable catalog defects. One was withdrawn after a live check showed it was a naming difference rather than a gap, six were held back at low confidence, and five duplicated others. Four were added by the analyst. None of the withdrawn or held items is in any count below.
What makes this category different is how it is bought. Nobody chooses a chainsaw or a backpack blower by its photograph. A professional compares power, speed, weight, vibration, noise and runtime — two dozen or more values per machine — and battery machines are typically listed twice, once as a bare tool and once with battery and charger. The same machine, two records, and every field in one should agree with the other.
In most categories a wrong field costs a click. Here the specification table is how one machine is chosen over another — and a single impossible number teaches the buyer to distrust all the others.
Model names, part numbers, exact specification values and the manufacturer's own vocabulary have been removed or generalized, because on a manufacturer's catalog a model and a value together identify the brand. Ratios and counts are exact.
What's inside
- At a glance — the severity split, where the findings concentrate, and how the read was done.
- What a buyer runs into first — values no machine could have, and zeros standing in for values nobody entered.
- The receipts — one machine described two ways, and the figures the most powerful models leave out.
- A zero is not a blank — why most of this never shows up on a completeness report.
- Where it traces back, and what's next — the six mechanisms most of these findings collapse into, and the order to fix in.
Nothing was supplied and no internal system was touched. Everything below was read from the manufacturer's public product pages, and the headline findings were re-checked live two days later.

Analyze
Surface defects, rate severity, and bind each one to the products and values behind it.
30 findings, 7 themes, 6 causes.
Machine-surfaced signals from a cold read, not a verified defect list. Some will prove intentional, which is why each is tied to the values behind it. No legal conclusion is drawn about any noise, vibration or emissions figure.
What a buyer runs into first.
A specification is only useful if it can be believed. The lead finding is a set of values no machine could have — and in most cases the catalog itself holds the right answer, usually on the product next to it.
Critical · Values that cannot be true
A gas chainsaw rated at ten times its sibling's power speed, with an oil tank a hundred times the size.
Two errors of two different kinds on one record: an inserted zero and a dropped decimal. Its sibling has the same engine displacement and publishes the values that make both errors plain.
Field
The saw · its sibling
Verdict
Maximum power speed
ten times the sibling's figure
inserted zero
Oil tank volume
a hundred times the sibling's figure
dropped decimal
Cylinder displacement
identical
agree
A range filter or a comparison tool takes both numbers at face value — and a buyer who reads either one learns to discount every other figure in the table.
Critical · Values that cannot be true
Zero, where a value belongs.
A hedge trimmer on a zero-volt battery. A spark plug with no gap. A brushcutter whose guaranteed sound power and both handle-vibration figures read zero, beside a real measured sound figure on the same record. A battery saw whose oil pump delivers nothing, on both of its listings. A bundle sold with battery and charger that records none included. Each zero sits in a field the catalog's comparable products fill.
One zero reached the storefront itself. A large professional saw sold without bar and chain records a zero-length bar — and on the day of the live check, the chainsaw page's bar-length filter began at zero. In the data EKOM read, that saw is the one chainsaw with a zero-length bar. One record is enough to set the scale every shopper in the category sees.
One machine, two answers.
Battery machines are typically listed twice: as a bare tool, and with battery and charger. The motor, the pump and the vibration at the handle are the same in both boxes. On five models, the two records disagree.

Hardware does not change with the box it ships in. When two listings of one machine disagree, a buyer comparing them is told they are two different machines — and asks which one they would receive.
The voltage disagreement is not simply an error on one side. Across the range, several battery products state one voltage for the platform and others state another; the blower's two listings take opposite sides. Which convention the storefront follows is the manufacturer's call, and the study reports it as a question rather than a correction.
Also in this theme: a two-battery bundle that records one battery; a blower whose total weight is lower than its weight without the battery, on both listings; and a saw whose oil pump minimum and maximum are the same figure where its sibling's differ. Eight findings in all, two critical.
The figures the biggest machines leave out.
Noise, vibration and emissions are the figures an operator, a fleet buyer or a municipality asks about first. The range publishes them on most machines — which is what makes the gaps visible.
Critical · Noise, vibration and emissions
The two most powerful backpack blowers publish no sound, no vibration and no emissions figure.
Their smaller siblings publish all three sound values and a vibration figure; these two, which share one engine, publish none — and leave their exhaust-emissions field blank as well. The analyst's recount found five products in the range with no sound data at all. EKOM cannot supply these values and does not: they live in the manufacturer's own product documentation.
High · Vocabulary and format
Two words for one fuel, split exactly along one category.
Thirteen products — every gas leaf blower, and only leaf blowers — name their fuel with the British word. Every other gas machine uses the American one. On the leaf-blower page the fuel filter reads one way; on the chainsaw, hedge-trimmer and brushcutter pages it reads the other. Anything that reads fuel across the range — site search, a dealer's import, a shopping feed, an assistant asked for gas-powered equipment — sees two fuels, and a query in the American word returns no leaf blowers at all.
Also in this theme: a unit qualifier on three blowers and not the rest; a thousands separator on the two largest air-flow values only; units typed into fields that elsewhere hold bare numbers; a placeholder dash where a blank belongs; and engine displacement filled in one unit system per category. And one finding the automated pass rated critical was withdrawn: it read blower vibration as missing everywhere, when the blowers publish it under one of two field names. The real finding is the two names.
One idea about the findings rather than more findings — because it explains why most of this would never appear on a completeness report.
Most of what this study found is not missing. The zero-volt battery is filled in. The zero-gap spark plug is filled in. The oil pump that delivers nothing is filled in. A completeness check — the instrument most catalogs are measured with — scores every one of those fields at a hundred percent, and every one of them gives an answer no machine could give. A blank at least admits it does not know. A zero is a number, and every filter, sort and comparison will use it.
Medium · The promotions source
Of 61 promotions in the list the product pages read, 54 had already ended.
Badges are built from a separate list of offers, each with an end date. The oldest still present had ended nearly two years before the read, and the date columns mix two formats that any consumer expecting one would misread. No unlaunched promotion was visible. Nothing flags this, and that is the point: an expired row renders no badge, exactly as a product with no promotion does. A dead offer produces no error and no support ticket, so the list grows for as long as nobody reads it directly.
What the range does well
The analyst checked 2,125 numeric values against the formatted strings the storefront renders from them and found no disagreement. Every product carries a SKU, a part number and a URL, each unique; price and availability are present throughout. The keys that join a product to an order are clean. The defects are in what was entered, not in how it is displayed — which is what makes them correctable by pattern.
30 findings sounds like 30 problems. Most of them collapse into six upstream mechanisms — and a mechanism can be fixed once and stopped from recurring. Each tell below is a pattern in the data; the mechanism is EKOM's reading of it.
Each packaging variant kept as its own record
The tell: the contradictions come in pairs — a tool-only and a battery-included listing of one machine, usually with one side right and the other wrong or blank. It produced the brushed-and-brushless compact saw, the zero-volt hedge trimmer and the bundle with no vibration figures.
A missing value written as zero
The tell: the zeros land in fields the catalog's comparable products fill, and read as the default of an empty numeric field rather than as a measurement.
Gas leaf blowers loaded on a path of their own
The tell: one product family carries conventions no other category uses — its own word for fuel, its own unit qualifier, its own name for the vibration field.
Units and formats typed by hand
The tell: the same field holds a bare number on one product and a number with a unit, a separator or a placeholder on the next.
One record transcribed badly
The tell: two unrelated errors of different kinds on the same product, with a correct sibling beside it.
A promotions list nothing prunes
The tell: an expired row and no row look identical on the page.
Correcting the bundle listings one by one fixes today's contradictions. Making the battery-included listing inherit its hardware specification from the bare tool — so motor, pump, vibration and voltage are entered once — fixes them and every bundle launched after.
On the day of the live check, the bar-length filter on the manufacturer's chainsaw page began at zero. In the data EKOM read, the one zero-length bar belongs to a single record — and one record is enough to set the scale every shopper in the category sees.
A power-equipment catalog sells engineering as much as machines. The dealer at the counter used to answer the question of which saw, which blower, which battery. Online, the specification table answers it alone — and it travels further than the page, into dealers' systems, shopping feeds and comparison tools that never see the photography. These findings are what happens when one machine is recorded twice and nothing holds the two records together. Nobody decided that a bundle should describe a different motor. It was never anybody's job to check.
What this class of defect costs is not a sale — it is trust in the table. A professional who reads an impossible speed discounts every other figure beside it. A buyer filtering by battery platform loses a machine recorded at zero volts. The two most powerful blowers arrive in any noise comparison with nothing to compare.
A second clock runs underneath. Buyers comparing equipment increasingly start with an assistant rather than a search box, and an assistant reads the fields before anything else: it checks the voltage, the weight, the vibration, the classification. Where two listings of one machine contradict each other, it cannot know which to believe; where a figure is blank, the machine is absent from the answer. Those are not rankings to trade off. They are wrong answers, and they do not correct themselves.
Three moves, in order. The first needs no new data at all — and the figures that need the manufacturer's documentation deliberately wait.
This pass read and diagnosed. The same structural understanding powers what follows — turning a diagnosed catalog into one a buyer can compare from with confidence.
1 · Apply the corrections the record already answers for itself
Replace each impossible value with its sibling's where a sibling publishes it, and with a blank where none does. Align each bundle's hardware fields to its twin. Fold the two fuel words and the two vibration field names into one each, and normalize units, separators and placeholders. Approved as patterns, not product by product.
2 · Settle the questions that gate the rest
Which voltage convention the storefront states; the sound, vibration and emissions figures the largest blowers leave out; the correct spark-plug gap; where each unclassified saw belongs in the line. All of these come from inside the manufacturer first, and EKOM does not supply them.
3 · Hold the line at intake
Keep ongoing intelligence where engineering data meets the storefront, so the next bundle that drifts from its twin — or the next zero standing in for a value — is caught as it lands rather than found later by a buyer comparing from it.
This is how EKOM moves a catalog from insight to impact —
and keeps every specification reading right as the range grows.
