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’s different? The 5 differences that matter most, from the published figures.
- FasTrak SDX uses a Kawasaki FX730 engine; Radius S-Series (60 in) uses a Kawasaki FR730 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.
- FasTrak SDX holds 8.5 gal (32.2 L) of fuel; Radius S-Series (60 in) holds 7 gal (26.5 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.
- FasTrak SDX has a published top speed of 10 mph; Radius S-Series (60 in) has a published top speed of 9 mph, a 1 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- FasTrak SDX cuts from 1.5 in (38 mm) to 4.5 in (114 mm); Radius S-Series (60 in) cuts from 1.5 in (38 mm) to 5 in (127 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- FasTrak SDX weighs 944 lbs (428.2 kg); Radius S-Series (60 in) weighs 903 lbs (409.6 kg), a 41 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What FasTrak SDX's weight means for a trailer ›
