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.

What’s different? The 5 differences that matter most, from the published figures.
- Exmark Radius X-Series Mower uses a Kawasaki FX691V engine; RIDGELINE 52 uses a Kawasaki FS651V 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.
- Exmark Radius X-Series Mower lists at $9,999; RIDGELINE 52 lists at $6,799, a $3,200 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- Exmark Radius X-Series Mower holds 7 gal (26.5 L) of fuel; RIDGELINE 52 holds 4.5 gal (17 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.
- Exmark Radius X-Series Mower has a published top speed of 9 mph; RIDGELINE 52 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.
- Exmark Radius X-Series Mower cuts from 1.5 in (38 mm) to 5 in (127 mm); RIDGELINE 52 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.
calculated figures and what isn’t comparable

- Exmark Radius X-Series Mower works out to 3.8 acres/hour; RIDGELINE 52 works out to 2.9 acres/hour, a 0.8 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.
