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’s different? The 5 differences that matter most, from the published figures.
- PRO-TURN 552 KAWASAKI holds 47.3 L (12.5 gal) of fuel; Z252KH-54 holds 16.3 L (4.3 gal) of fuel, a 31 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.
- PRO-TURN 552 KAWASAKI uses a Kawasaki® engine; Z252KH-54 uses a Kohler K745 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.
- PRO-TURN 552 KAWASAKI has a published top speed of 15 mph; Z252KH-54 has a published top speed of 8 mph, a 7 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- PRO-TURN 552 KAWASAKI weighs 656.4 kg (1,447 lbs); Z252KH-54 weighs 375.2 kg (827 lbs), a 281.1 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What PRO-TURN 552 KAWASAKI's weight means for a trailer ›
- PRO-TURN 552 KAWASAKI cuts from 25 mm (1 in) to 140 mm (5.5 in); Z252KH-54 cuts from 38 mm (1.5 in) to 114 mm (4.5 in). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
