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.
- Exmark Exmark Navigator Mower — commercial: daily paid use and high acreage; 48-inch deck
- Exmark Navigator (NVS 48 in EFI) — commercial: daily paid use and high acreage; 48-inch deck; gas powered
What’s different? The 3 differences that matter most, from the published figures.
- Exmark Navigator Mower uses a Kohler CH749 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.
- Exmark Navigator Mower has a 26.5 hp engine; Navigator (NVS 48 in EFI) has a 23 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.
- Exmark Navigator Mower has a 45.6 ci (747 cc) engine; Navigator (NVS 48 in EFI) has a 44.2 ci (725 cc) engine, a 1.3 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
