Compare Mowers
Prices are the recommended retail prices published by each manufacturer’s Australian site, in AUD, as read on the date shown on each model’s page; dealers set the final price.
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.
Best suited for
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.
- Kubota Z422KW-54 — prosumer: larger home properties and light acreage; 54-inch deck; gas powered

What’s different? The 5 differences that matter most, from the published figures.
- Z422KW-54 uses a Kawasaki GH7301V 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.
- Z422KW-54 holds 25.7 L (6.8 gal) of fuel; Z232KW-42 holds 13.6 L (3.6 gal) of fuel, a 12.1 L 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.
- Z422KW-54 has a 2-HST w/Gear reduction 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.
- Z422KW-54 has a published top speed of 9.9 mph; Z232KW-42 has a published top speed of 6.5 mph, a 3.4 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Z422KW-54 runs on Petrol; Z232KW-42 runs on Gasoline. Fuel type sets what you buy and store; it is not a measure of power.
