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.
- Z724KHNC-54 has a Parker HTG14 transmission; Rebel SD has a 4400 Hydro-Gear® 16cc Integrated Transaxle transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- Z724KHNC-54 holds 11.6 gal (43.9 L) of fuel; Rebel SD holds 13 gal (49.2 L) of fuel, a 1.4 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.
- Z724KHNC-54 has a 23.5 hp engine; Rebel SD has a 25 hp engine, a 1.5 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.
- Z724KHNC-54 has a published top speed of 11.2 mph; Rebel SD has a published top speed of 12 mph, a 0.8 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Z724KHNC-54 weighs 1,184 lbs (537 kg); Rebel SD weighs 1,257 lbs (570.2 kg), a 73 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Z724KHNC-54's weight means for a trailer ›
calculated figures and what isn’t comparable
Calculated by MowerFacts
- Z724KHNC-54 works out to 4.9 acres/hour; Rebel SD works out to 5.2 acres/hour, a 0.3 acres/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.
