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.
- Z421KWTNC-60 uses a Kawasaki FS730V engine; Z232KW-42 uses a Kawasaki FR651V 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.
- Z421KWTNC-60 has a 60 in (1,524 mm) deck; Z232KW-42 has a 42 in (1,067 mm) deck, a 18 in difference. Deck width sets how much grass each pass covers. Mowing time also depends on ground speed, turns and obstacles, so a wider deck alone does not fix the job's length. Time both decks on your own lawn ›
- Z421KWTNC-60 holds 6.8 gal (25.7 L) of fuel; Z232KW-42 holds 3.6 gal (13.6 L) of fuel, a 3.2 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.
- Z421KWTNC-60 has a Hydro-Gear Commercial ZT-3600 transmission; Z232KW-42 has a Hydro-Gear ZT-2200 transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- Z421KWTNC-60 has a published top speed of 10 mph; Z232KW-42 has a published top speed of 6.5 mph, a 3.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
