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
What’s different? The 5 differences that matter most, from the published figures.
- ZT HD 52 KAWASAKI lists at $6,949; Patriot lists at $8,599 to $10,559, a $1,650 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- ZT HD 52 KAWASAKI holds 5.1 gal (19.3 L) of fuel; Patriot holds 6.5 gal (24.6 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.
- ZT HD 52 KAWASAKI weighs 817 lbs (370.6 kg); Patriot weighs 911 lbs (413.2 kg), a 94 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZT HD 52 KAWASAKI's weight means for a trailer ›
- ZT HD 52 KAWASAKI has a published top speed of 8 mph; Patriot has a published top speed of 8.5 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.
- ZT HD 52 KAWASAKI has a 23 hp engine; Patriot has a 22 hp engine, a 1 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.
calculated figures and what isn’t comparable
Calculated by MowerFacts
- ZT HD 52 KAWASAKI works out to 3.4 acres/hour; Patriot works out to 3.6 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.

- Displacement: not published for Patriot.
- Fuel Type: not published for Patriot.
- Deck Material: not published for Patriot.

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.
