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 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.
- Z724XKWNC-48 holds 11.6 gal (43.9 L) of fuel; ZT HD 48 KAWASAKI holds 5.1 gal (19.3 L) of fuel, a 6.5 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.
- Z724XKWNC-48 weighs 1,186 lbs (538.1 kg); ZT HD 48 KAWASAKI weighs 802 lbs (363.8 kg), a 384 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Z724XKWNC-48's weight means for a trailer ›
- Z724XKWNC-48 has a published top speed of 11.2 mph; ZT HD 48 KAWASAKI has a published top speed of 8 mph, a 3.2 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Z724XKWNC-48 has Belt drive; ZT HD 48 KAWASAKI has Hydro-Gear® ZT-3100® Transaxles drive.
- Z724XKWNC-48 has a 23.5 hp engine; ZT HD 48 KAWASAKI has a 23 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.
