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.
- Husqvarna Z454 — commercial: daily paid use and high acreage; 54-inch deck; gas powered
- Ariens RIDGELINE 52 — commercial: daily paid use and high acreage; 52-inch deck; gas powered
What’s different? The 4 differences that matter most, from the published figures.
- Z454 lists at $9,199; RIDGELINE 52 lists at $6,799, a $2,400 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- Z454 has a published top speed of 10 mph; RIDGELINE 52 has a published top speed of 7 mph, a 3 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Z454 holds 6 gal (22.7 L) of fuel; RIDGELINE 52 holds 4.5 gal (17 L) of fuel, a 1.5 gal difference. Tank size bounds how long a machine runs between stops. Consumption varies with engine, load and speed, so hours per tank are not fixed.
- Z454 has a 54 in (1,372 mm) deck; RIDGELINE 52 has a 52 in (1,321 mm) deck, a 2 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 and what isn’t comparable
Calculated by MowerFacts
- Z454 works out to 4.4 acres/hour; RIDGELINE 52 works out to 2.9 acres/hour, a 1.4 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.
