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.

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.

What’s different? The 5 differences that matter most, from the published figures.
- Radius S-Series (48 in) uses a Kawasaki FR691 engine; PRO X 448 uses a Kohler® engine. The engine maker builds the engine; the mower maker chooses the model, rating and fit, so the badge alone does not settle output or longevity.
- Radius S-Series (48 in) has a published top speed of 9 mph; PRO X 448 has a published top speed of 7 mph, a 2 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Radius S-Series (48 in) holds 7 gal (26.5 L) of fuel; PRO X 448 holds 5.4 gal (20.4 L) of fuel, a 1.6 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.
- Radius S-Series (48 in) lists at $7,199; PRO X 448 lists at $7,799, a $600 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- Radius S-Series (48 in) cuts from 1.5 in (38 mm) to 5 in (127 mm); PRO X 448 cuts from 1.5 in (38 mm) to 4.5 in (114 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
