Compare Mowers
List prices are the manufacturer’s published figures, re-checked daily; they exclude tax, freight and dealer setup.
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 48 KAWASAKI has a Fabricated X-Factor® deck; MZ Magnum has a 7 gauge / 4.5mm deck.
- ZT X 48 KAWASAKI holds 3.5 gal (13.2 L) of fuel; MZ Magnum holds 5 gal (18.9 L) of fuel, a 1.5 gal 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 48 KAWASAKI has a published top speed of 7 mph; MZ Magnum has a published top speed of 6 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.
- ZT X 48 KAWASAKI weighs 679 lbs (308 kg); MZ Magnum weighs 659 lbs (299 kg), a 20 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZT X 48 KAWASAKI's weight means for a trailer ›
- ZT X 48 KAWASAKI has a 21.5 hp engine; MZ Magnum has a 22 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.
