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.
- SFCII-30 uses a Kohler® Command PRO® CV224 engine; FW15 Walk Behind Mower uses a Honda® GXV390 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.
- SFCII-30 lists at $2,999; FW15 Walk Behind Mower lists at $4,343, a $1,344 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- SFCII-30 has a 7 hp engine; FW15 Walk Behind Mower has a 10.2 hp engine, a 3.2 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.
- SFCII-30 weighs 202 lbs (91.6 kg); FW15 Walk Behind Mower weighs 285 lbs (129.3 kg), a 83 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What SFCII-30's weight means for a trailer ›
- SFCII-30 has a published top speed of 3.5 mph; FW15 Walk Behind Mower has a published top speed of 4 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.

Calculated by MowerFacts
- SFCII-30 works out to 0.8 acres/hour; FW15 Walk Behind Mower works out to 1.0 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.
