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.
- Rebel SD holds 13 gal (49.2 L) of fuel; MZ54 holds 5 gal (18.9 L) of fuel, a 8 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.
- Rebel SD uses a Kohler engine; MZ54 uses a Kawasaki engine. The engine maker builds the engine; the mower maker chooses the model, rating and fit, so the badge alone does not settle output or longevity.
- Rebel SD weighs 1,257 lbs (570.2 kg); MZ54 weighs 810 lbs (367.4 kg), a 447 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Rebel SD's weight means for a trailer ›
- Rebel SD has a 4400 Hydro-Gear® 16cc Integrated Transaxle transmission; MZ54 has a Hydrostatic transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- Rebel SD has a published top speed of 12 mph; MZ54 has a published top speed of 8.5 mph, a 3.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
