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.
- Scag Patriot — commercial: daily paid use and high acreage; 52-inch deck; gas powered
- Gravely HD PRO 52 KAWASAKI FT — commercial: daily paid use and high acreage; 52-inch deck; gas powered
What’s different? The 3 differences that matter most, from the published figures.
- Patriot holds 6.5 gal (24.6 L) of fuel; HD PRO 52 KAWASAKI FT holds 5.1 gal (19.3 L) of fuel, a 1.4 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 has a published top speed of 8.5 mph; HD PRO 52 KAWASAKI FT 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.
- Patriot lists at $8,599 to $10,559; HD PRO 52 KAWASAKI FT lists at $8,899, a $300 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
calculated figures and what isn’t comparable
Calculated by MowerFacts
- Patriot works out to 3.6 acres/hour; HD PRO 52 KAWASAKI FT works out to 3.4 acres/hour, a 0.2 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.

- Discharge: not published for Patriot.
- Cut height range: not published for HD PRO 52 KAWASAKI FT.
Verified means each manufacturer publishes the figure. A bigger number is only a bigger number; nothing here says which machine is better. The full specification table is below.
