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.
Best suited for
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.
- Kubota ZG222 — commercial: daily paid use and high acreage; 48-inch deck; gas powered
- Exmark Navigator (NVS 48 in EFI) — commercial: daily paid use and high acreage; 48-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- ZG222 uses a Kubota KGZ770-E2-MA3 engine; Navigator (NVS 48 in EFI) uses a Kohler ECH730 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.
- ZG222 has a published top speed of 9 mph; Navigator (NVS 48 in EFI) has a published top speed of 7 mph, a 2 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- ZG222 has a 22 hp engine; Navigator (NVS 48 in EFI) has a 23 hp engine, a 1 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.
- ZG222 has a 46.9 ci (768 cc) engine; Navigator (NVS 48 in EFI) has a 44.2 ci (725 cc) engine, a 2.6 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- ZG222 holds 7.1 gal (26.9 L) of fuel; Navigator (NVS 48 in EFI) holds 7.5 gal (28.4 L) of fuel, a 0.4 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.
