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.

What’s different? The 5 differences that matter most, from the published figures.
- Z42 Zero-Turn Mower uses a Troy-Bilt® engine; EDGE 42 BRIGGS uses a Briggs & Stratton® EXi2000 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.
- Z42 Zero-Turn Mower has a Hydro-Gear™ EZT-2200 transmission; EDGE 42 BRIGGS has a Hydrostatic transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- Z42 Zero-Turn Mower holds 3.5 gal (13.2 L) of fuel; EDGE 42 BRIGGS holds 2 gal (7.6 L) of fuel, a 1.5 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.
- Z42 Zero-Turn Mower has Hydrostatic drive; EDGE 42 BRIGGS has Hydro-Gear® EZT® Transaxles drive.
- Z42 Zero-Turn Mower carries a 3-year warranty; EDGE 42 BRIGGS carries a 2-year warranty, a 1 year difference. Warranty length is the maker's published term. Conditions and commercial-use limits differ between makers.
