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.

What’s different? The 5 differences that matter most, from the published figures.
- Z252KH-54 uses a Kohler K745 engine; Z242KW-48 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.
- Z252KH-54 has a 10-gauge steel deck; Z242KW-48 has a 10Ga deck.
- Z252KH-54 has a 25 hp engine; Z242KW-48 has a 21.5 hp engine, a 3.5 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.
- Z252KH-54 has a 1,372 mm (54 in) deck; Z242KW-48 has a 1,219 mm (48 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 ›
- Z252KH-54 has a 747 cc (45.6 ci) engine; Z242KW-48 has a 726 cc (44.3 ci) engine, a 21 cc difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
calculated figures and what isn’t comparable
Calculated by MowerFacts
- Z252KH-54 works out to 1.41 ha/hour; Z242KW-48 works out to 1.26 ha/hour, a 0.16 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.
Not comparable
- Cut height range: not published for Z242KW-48.
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.
