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.

- Troy-Bilt TBWC28B Self-Propelled Lawn Mower — residential: typical home lawns; 28-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- SFC-30 lists at $2,999; TBWC28B Self-Propelled Lawn Mower lists at $1,009, a $1,990 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- SFC-30 holds 1 gal (3.8 L) of fuel; TBWC28B Self-Propelled Lawn Mower holds 0.3 gal (1 L) of fuel, a 0.7 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.
- SFC-30 uses a Kohler® Command PRO® CV224 engine; TBWC28B Self-Propelled Lawn Mower uses a Briggs & Stratton® 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.
- SFC-30 has GT MV 702 Transmission drive; TBWC28B Self-Propelled Lawn Mower has RWD drive.
- SFC-30 cuts from 1.5 in (38 mm) to 5 in (127 mm); TBWC28B Self-Propelled Lawn Mower cuts from 1.3 in (32 mm) to 3.7 in (95 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
