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.

What’s different? The 5 differences that matter most, from the published figures.
- Patriot uses a Kawasaki® FX Series engine; 500S Zero Turn Mower (52 in / 5902102) uses a Briggs & Stratton® CXi 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.
- Patriot holds 6.5 gal (24.6 L) of fuel; 500S Zero Turn Mower (52 in / 5902102) holds 3 gal (11.4 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; 500S Zero Turn Mower (52 in / 5902102) lists at $7,588, a $1,011 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- Patriot has a 22 hp engine; 500S Zero Turn Mower (52 in / 5902102) has a 25 hp engine, a 3 hp difference. Published horsepower is the maker's rating at a stated engine speed. It is a different measure from displacement, and two engines of equal rating can pull differently.
- Patriot cuts from 1.5 in (38 mm) to 5 in (127 mm); 500S Zero Turn Mower (52 in / 5902102) 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.
