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.

- Exmark Radius S-Series (60 in) — commercial: daily paid use and high acreage; 60-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- Spartan RT-Pro holds 9.5 gal (36 L) of fuel; Radius S-Series (60 in) holds 7 gal (26.5 L) of fuel, a 2.5 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.
- Spartan RT-Pro weighs 1,099 lbs (498.5 kg); Radius S-Series (60 in) weighs 903 lbs (409.6 kg), a 196 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Spartan RT-Pro's weight means for a trailer ›
- Spartan RT-Pro has a published top speed of 11 mph; Radius S-Series (60 in) has a published top speed of 9 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.
- Spartan RT-Pro cuts from 1.5 in (38 mm) to 4.8 in (121 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.
- Spartan RT-Pro lists at $8,799; Radius S-Series (60 in) lists at $8,499, a $300 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
