Compare Mowers
List prices are the manufacturer’s published figures, re-checked daily; they exclude tax, freight and dealer setup.
A side-by-side reference of each model's stated specifications. MowerFacts doesn’t give opinions: where a published, spec-derived rule can separate machines we mark a Data Pick and show the rule; here, read the values and decide what fits your needs.
Best suited for
What each model is built for, from its duty class and key specs. This is a neutral reference — MowerFacts does not rank one model above another.
- Ariens RIDGELINE 52 — commercial: daily paid use and high acreage; 52-inch deck; gas powered
- Ariens RIDGELINE 48 — commercial: daily paid use and high acreage; 48-inch deck; gas powered
What’s different? The 1 difference that matter most, from the published figures.
- RIDGELINE 52 has a 52 in (1,321 mm) deck; RIDGELINE 48 has a 48 in (1,219 mm) deck, a 4 in difference. Deck width sets how much grass each pass covers. Mowing time also depends on ground speed, turns and obstacles, so a wider deck alone does not fix the job's length. Time both decks on your own lawn ›
calculated figures
Calculated by MowerFacts
- RIDGELINE 52 works out to 2.9 acres/hour; RIDGELINE 48 works out to 2.7 acres/hour, a 0.2 acres/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.
Verified means each manufacturer publishes the figure. A bigger number is only a bigger number; nothing here says which machine is better. The full specification table is below.
