Changelog

  1. Owner sentiment added: 12,129 Reddit posts, comments and YouTube comments read one by one; six models have enough owner posts to score.

  2. Dashboard: filter by brand, use and terrain; written takeaways; three comparison charts including coverage against slope. Manufacturers can now request a benchmark.

  3. Research hub launched; six more categories announced.

  4. Robotic mowers refreshed from the September Velocity catalog; prices, cut widths and slope ratings checked against manufacturers (13 corrections).

  5. Robotic mower index: 26 models scored from the Velocity fleet catalog.

How to read this chart
Each column is one machine, colored by its maker, ranked left to right. The photo, maker mark and name sit underneath; select any machine to open its full page. The model picker at the top changes every chart on the page at once.
Where the numbers come from
Coverage and output come from the fleet catalog Velocity, our planning software, uses to size and dispatch real machines on real properties. Daily coverage is the 12-hour mowing cycle; Husqvarna's commercial EPOS machines are rated on their 24-hour basis. List prices, cutting widths and slope ratings are checked against each manufacturer's own US pages.

What cost to run includes
Equipment only: the list price spread over a 5-year life and a 32-week mowing season, divided by the acres the machine covers per day. Labor, power, blades and service are not included, so real running costs are higher for every machine.

Why our plans use lower limits
These are the makers' published maximums. When we plan a property we hold each machine to a more conservative planning limit, because wet grass, turns across a slope and boundary edges all reduce grip.

Share of first-hand owner verdicts that recommend the brand, from forums where owners of every brand post side by side (last 24 months). Ranked on the low end of the range, so a brand needs volume to lead. 50+ verdicts to rank.

How this is built
Public owner posts from Reddit (plus app store reviews for the app score) are read one by one by Jev, a judgment model from TypeSafe: is the writer a first-hand owner, is the post a verdict, did they recommend it or regret it, did they switch brands, which problems did they have. Sponsored posts, free review units and dealers are excluded, and no single author counts more than three times per brand. Code does all the counting. Accuracy was measured on 390 hand-labelled posts before the run.
What this can't tell you yet
Brands with few public owner verdicts, including Kress, Sunseeker and most commercial machines, show as not enough data. Their scores will come from X, Facebook owner groups, our own customer survey and fleet data.

Every model, side by side

Sort by any column. Each bar shows where the machine sits against the best in the current selection.

How we score

Coverage and output come from the fleet catalog that Velocity, our planning software, uses to size and dispatch real machines. List prices, cutting widths and slope ratings are checked against each manufacturer’s own published figures, and every correction is recorded with its source. No manufacturer pays to be listed.

Output is square feet cut per hour of active mowing. Daily coverageis the 12-hour mowing cycle our optimizer plans with; Husqvarna’s commercial EPOS machines run around the clock and are rated on their 24-hour basis. Cost to runspreads each machine’s price over a 5-year life and a 32-week season, per acre mowed. Value is output per $1,000 of price.

Models marked claimedcarry manufacturer figures we haven’t verified in the field yet. They appear in the ranking but can’t hold a top spot.

Questions

Where do the numbers come from?+

From the fleet catalog our planning software, Velocity, uses to size and dispatch real machines on real properties. Models marked claimed carry manufacturer specs we haven't verified in the field yet, and they can't hold a top spot.

How is cost to run calculated?+

Each machine's price spread over a 5-year life and a 32-week mowing season, divided by the acres it covers in a day. It shows what an acre of mowing costs in equipment, before labor, power and service.

What does value mean?+

Square feet of active mowing per hour for every $1,000 of price. A higher number means more grass cut for the money.

Do manufacturers pay to be listed?+

No. Rankings are computed from the data; nothing is placed by hand. We install and service several of these brands, and the index shows every model we plan with, including the ones that score poorly.

What's coming next?+

Range pickers, bunker rakes, line marking, aerial and water drones, spray application, and soil sensors and irrigation. Each will be benchmarked on the measures listed in its section.

Index updates

  1. Owner sentiment added: 12,129 Reddit posts, comments and YouTube comments read one by one; six models have enough owner posts to score.

  2. Dashboard: filter by brand, use and terrain; written takeaways; three comparison charts including coverage against slope. Manufacturers can now request a benchmark.

  3. Research hub launched; six more categories announced.

  4. Robotic mowers refreshed from the September Velocity catalog; prices, cut widths and slope ratings checked against manufacturers (13 corrections).

  5. Robotic mower index: 26 models scored from the Velocity fleet catalog.

Benchmarks tell you the machine. We’ll size the fleet.
