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.
- ZD1011-48 uses a Kubota D782-E4-ZD-3 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.
- ZD1011-48 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.
- ZD1011-48 has a 19.3 hp engine; Navigator (NVS 48 in EFI) has a 23 hp engine, a 3.7 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.
- ZD1011-48 holds 6 gal (22.7 L) of fuel; Navigator (NVS 48 in EFI) holds 7.5 gal (28.4 L) of fuel, a 1.5 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.
- ZD1011-48 weighs 1,296 lbs (587.9 kg); Navigator (NVS 48 in EFI) weighs 1,191 lbs (540.2 kg), a 105 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZD1011-48's weight means for a trailer ›
