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’s different? The 5 differences that matter most, from the published figures.
- MZ Magnum has a 7 gauge / 4.5mm deck; ZT X 48 KAWASAKI has a Fabricated X-Factor® deck.
- MZ Magnum holds 18.9 L (5 gal) of fuel; ZT X 48 KAWASAKI holds 13.2 L (3.5 gal) of fuel, a 5.7 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.
- MZ Magnum has a published top speed of 6 mph; ZT X 48 KAWASAKI has a published top speed of 7 mph, a 1 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- MZ Magnum weighs 299 kg (659 lbs); ZT X 48 KAWASAKI weighs 308 kg (679 lbs), a 9 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What MZ Magnum's weight means for a trailer ›
- MZ Magnum has a 22 hp engine; ZT X 48 KAWASAKI has a 21.5 hp engine, a 0.5 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.
