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.

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 Z412KW-48 — prosumer: larger home properties and light acreage; 48-inch deck; gas powered
- Kubota Z422KW-54 — prosumer: larger home properties and light acreage; 54-inch deck; gas powered
What’s different? The 3 differences that matter most, from the published figures.
- Z412KW-48 uses a Kawasaki GH7302V engine; Z422KW-54 uses a Kawasaki GH7301V 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.
- Z412KW-48 has a 1,219 mm (48 in) deck; Z422KW-54 has a 1,372 mm (54 in) deck, a 153 mm 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 ›
- Z412KW-48 has a 22 hp engine; Z422KW-54 has a 24 hp engine, a 2 hp difference. Published horsepower is the maker's rating at a stated engine speed. It is a different measure from displacement, and two engines of equal rating can pull differently.
calculated figures
Calculated by MowerFacts
- Z412KW-48 works out to 1.56 ha/hour; Z422KW-54 works out to 1.76 ha/hour, a 0.20 ha/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.
Verified means each manufacturer publishes the figure. A bigger number is only a bigger number; nothing here says which machine is better. The full specification table is below.
