Our method
How we pick
This is the most important page on the site, because it is where we show our working. We don’t run a test lawn. Here is what we do instead — every step of it, so you can check us.
The short version. We compile published manufacturer specifications and seed labels, do the deck-width and pounds-of-nitrogen math, cross-read owner manuals, cite third-party research by name, and check live prices. We have not mowed, sown or spread with any of this equipment, and we say so on every page. Where somebody has genuinely measured it, we link them.
What we do
- Compile the published specs. Mower deck widths and drive types, battery voltage and amp-hours, engine displacement, blower CFM and MPH, fertilizer NPK analyses and stated coverage, the species printed on a grass seed label, aerator tine type and working width — the numbers manufacturers publish and most lawn-care pages never show. We put them side by side in tables so you can compare like with like.
- Do the arithmetic. We convert deck width into the number of passes a lawn of a given size actually takes, and we convert an NPK analysis into pounds of product per 1,000 square feet. Both calculations are shown in full in the best lawn mower for a large yard and your lawn fertilizer schedule. This is math, not measurement — but it is the same math a groundsman starts from.
- Cross-read the labels and cite the research. Where we make an agronomic claim — which grass species tolerates shade, what relieves soil compaction, how fertilizer runoff behaves — we cite a named source such as the National Turfgrass Evaluation Program or the EPA and link it, rather than stating it in our own voice.
- Check the live price.Every price on the site comes from Amazon’s API and is stamped with the day we checked it. If our data is more than 48 hours old, the number disappears and the button reads “Check price” — we never show a figure that has gone stale.
What we don’t do
- We don’t mow with the mowers, sow the seed, or run a soil lab.
- We don’t own the products or accept free samples from manufacturers.
- We don’t take payment for placement, and no brand sees our copy before you do.
- We don’t invent prices, ratings, review counts, or specifications. Ever.
How a pick gets made
For each category we decide the two or three specs that actually matter — for a mower, that’s deck width, drive type and capacity; for grass seed, the species and whether it spreads; for a blower, CFM rather than MPH; for an aerator, whether the tines are hollow. We score each product against a small set of category-relevant metrics, publish those per-metric scores on the product card, and rank on the total. Those scores are our judgments from documented specifications — they are not lab measurements, and we label them that way.
Every roundup carries a genuine “skip this” — a product we recommend against, and why. Recommending against something is the cheapest honest signal available, and almost nobody in the lawn-care space does it.
When we defer to someone else
Sometimes measured performance genuinely decides a question and published specs can’t. When that happens we say so and link the people who did the measuring — including sites with real test labs whose data is better than any spec sheet. Pointing you to a competitor’s superior testing isn’t a weakness; it’s the clearest possible sign that we’re not pretending.
How often we re-check
- Prices: live, every render, behind the 48-hour freshness gate above.
- Spec tables:re-verified against manufacturer sheets quarterly, and re-stamped only when we’ve actually re-checked — a false “last verified” date is worse than none.
- Product line-ups: reviewed twice a year and on major new releases or discontinuations.
- Health guidance: re-checked annually against the cited authority.
Found a mistake?
Tell us. If a spec is wrong, a product has been discontinued, or you think a ranking is off, get in touch— corrections are exactly the kind of mail we want, and we’ll fix and re-stamp the page.
