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.
- Z781KWiTW-54 holds 11.6 gal (43.9 L) of fuel; Z232KW-42 holds 3.6 gal (13.6 L) of fuel, a 8 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.
- Z781KWiTW-54 weighs 1,254 lbs (568.8 kg); Z232KW-42 weighs 643 lbs (291.7 kg), a 611 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Z781KWiTW-54's weight means for a trailer ›
- Z781KWiTW-54 uses a Kawasaki FX850VEFI 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.
- Z781KWiTW-54 has a published top speed of 11.2 mph; Z232KW-42 has a published top speed of 6.5 mph, a 4.7 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Z781KWiTW-54 has a Parker HTG14 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.
