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.
- FW15 Walk Behind Mower uses a Honda® GXV390 engine; SFC-30 uses a Kohler® Command PRO® CV224 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.
- FW15 Walk Behind Mower lists at $4,343; SFC-30 lists at $2,999, a $1,344 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- FW15 Walk Behind Mower has a 10.2 hp engine; SFC-30 has a 7 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.
- FW15 Walk Behind Mower has a 23.7 ci (389 cc) engine; SFC-30 has a 13.7 ci (224 cc) engine, a 10.1 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- FW15 Walk Behind Mower weighs 285 lbs (129.3 kg); SFC-30 weighs 220 lbs (99.8 kg), a 65 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What FW15 Walk Behind Mower's weight means for a trailer ›
