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 48 — commercial: daily paid use and high acreage; 48-inch deck; gas powered
- Husqvarna Z448 — commercial: daily paid use and high acreage; 48-inch deck; gas powered
What’s different? The 3 differences that matter most, from the published figures.
- RIDGELINE 48 has a published top speed of 7 mph; Z448 has a published top speed of 10 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.
- RIDGELINE 48 lists at $6,799; Z448 lists at $8,899, a $2,100 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- RIDGELINE 48 holds 4.5 gal (17 L) of fuel; Z448 holds 6 gal (22.7 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.
calculated figures and what isn’t comparable
Calculated by MowerFacts
- RIDGELINE 48 works out to 2.7 acres/hour; Z448 works out to 3.9 acres/hour, a 1.2 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.
