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.

- Gravely PRO-TURN 52 KAWASAKI FX — commercial: daily paid use and high acreage; 52-inch deck; gas powered
What’s different? The 4 differences that matter most, from the published figures.
- Patriot holds 6.5 gal (24.6 L) of fuel; PRO-TURN 52 KAWASAKI FX holds 10 gal (37.9 L) of fuel, a 3.5 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.
- Patriot lists at $8,599 to $10,559; PRO-TURN 52 KAWASAKI FX lists at $9,899, a $1,300 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- Patriot weighs 911 lbs (413.2 kg); PRO-TURN 52 KAWASAKI FX weighs 988 lbs (448.1 kg), a 77 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Patriot's weight means for a trailer ›
- Patriot has a published top speed of 8.5 mph; PRO-TURN 52 KAWASAKI FX has a published top speed of 8 mph, a 0.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
