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.
- Z751KWi-48 uses a Kawasaki FX730V EFI engine; Tiger Cat II uses a Kawasaki® FX Series 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.
- Z751KWi-48 has Belt drive; Tiger Cat II has Dual Pump and Motor drive.
- Z751KWi-48 has a 25.5 hp engine; Tiger Cat II has a 22 hp engine, a 3.5 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.
- Z751KWi-48 holds 11.6 gal (43.9 L) of fuel; Tiger Cat II holds 9.5 gal (36 L) of fuel, a 2.1 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.
- Z751KWi-48 has a published top speed of 11.2 mph; Tiger Cat II 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.
