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.

What’s different? The 5 differences that matter most, from the published figures.
- ZTM 50 uses a Masport engine; EDGE 52 KAWASAKI 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.
- ZTM 50 has a Hydro-Gear EZT (ZT-2200) transmission; EDGE 52 KAWASAKI has a Hydrostatic transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- ZTM 50 holds 11.4 L (3 gal) of fuel; EDGE 52 KAWASAKI holds 7.6 L (2 gal) of fuel, a 3.8 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.
- ZTM 50 has V-Belt drive; EDGE 52 KAWASAKI has Hydro-Gear® EZT® Transaxles drive.
- ZTM 50 lists at A$7,299; EDGE 52 KAWASAKI lists at A$8,299, a A$1,000 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
