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’s different? The 5 differences that matter most, from the published figures.
- SWZ Hydro-Drive lists at $8,449 to $11,329; SFCII-30 lists at $2,999, a $5,450 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- SWZ Hydro-Drive holds 5.5 gal (20.8 L) of fuel; SFCII-30 holds 1 gal (3.8 L) of fuel, a 4.5 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.
- SWZ Hydro-Drive weighs 515 lbs (233.6 kg); SFCII-30 weighs 202 lbs (91.6 kg), a 313 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What SWZ Hydro-Drive's weight means for a trailer ›
- SWZ Hydro-Drive has a 14 hp engine; SFCII-30 has a 7 hp engine, a 7 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.
- SWZ Hydro-Drive has a published top speed of 7.4 mph; SFCII-30 has a published top speed of 3.5 mph, a 3.9 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.

Calculated by MowerFacts
- SWZ Hydro-Drive works out to 2.2 acres/hour; SFCII-30 works out to 0.8 acres/hour, a 1.3 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.
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.
