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 HD 48 KAWASAKI has a Fabricated X-Factor® 3 deck; MZ Magnum has a 7 gauge / 4.5mm deck.
- ZT HD 48 KAWASAKI has a published top speed of 8 mph; MZ Magnum has a published top speed of 6 mph, a 2 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- ZT HD 48 KAWASAKI weighs 363.8 kg (802 lbs); MZ Magnum weighs 299 kg (659 lbs), a 64.8 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZT HD 48 KAWASAKI's weight means for a trailer ›
- ZT HD 48 KAWASAKI has a 23 hp engine; MZ Magnum has a 22 hp engine, a 1 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.
- ZT HD 48 KAWASAKI holds 19.3 L (5.1 gal) of fuel; MZ Magnum holds 18.9 L (5 gal) of fuel, a 0.4 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.
