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.
- ZT X 52 KAWASAKI uses a Kawasaki® engine; ZT Avenger uses a Kohler 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.
- ZT X 52 KAWASAKI holds 13.2 L (3.5 gal) of fuel; ZT Avenger holds 29.5 L (7.8 gal) of fuel, a 16.3 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.
- ZT X 52 KAWASAKI has a Fabricated X-Factor® deck; ZT Avenger has a 7 Gauge / 4.5mm deck.
- ZT X 52 KAWASAKI has a 11 ga deck; ZT Avenger has a 3/16" or 7-Gauge Thick Solid Steel deck.
- ZT X 52 KAWASAKI has a 23 hp engine; ZT Avenger has a 26 hp engine, a 3 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.
