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; IS600 Zero Turn Mower (52 in / 5901911) uses a Kawasaki® FS691V 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 has a published top speed of 8.5 mph; IS600 Zero Turn Mower (52 in / 5901911) has a published top speed of 10 mph, a 1.5 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; IS600 Zero Turn Mower (52 in / 5901911) lists at $9,624, a $1,025 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- Patriot cuts from 1.5 in (38 mm) to 5 in (127 mm); IS600 Zero Turn Mower (52 in / 5901911) 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.
- Patriot holds 6.5 gal (24.6 L) of fuel; IS600 Zero Turn Mower (52 in / 5901911) holds 6 gal (22.7 L) of fuel, a 0.5 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.
