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 F2690 — commercial: daily paid use and high acreage; 60-inch deck
What’s different? The 5 differences that matter most, from the published figures.
- ZD1021-60 holds 6.1 gal (23.1 L) of fuel; F2690 holds 16.1 gal (61 L) of fuel, a 10 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.
- ZD1021-60 uses a Diesel, liquid-cooled (3 cyl.) engine; F2690 uses a Kubota D1105 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.
- ZD1021-60 has a 2-HST w/Gear reduction transmission; F2690 has a Kubota HST transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- ZD1021-60 has a published top speed of 9 mph; F2690 has a published top speed of 12.4 mph, a 3.4 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- ZD1021-60 has a 54.8 ci (898 cc) engine; F2690 has a 68.5 ci (1,123 cc) engine, a 13.7 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.

Other verified differences
- ZD1021-60 has a 21.6 hp engine; F2690 has a 24.8 hp engine, a 3.2 hp difference.
- ZD1021-60 weighs 1,389 lbs (630 kg); F2690 weighs 1,590 lbs (721.2 kg), a 201 lbs difference.
Calculated by MowerFacts
- ZD1021-60 works out to 4.4 acres/hour; F2690 works out to 6.0 acres/hour, a 1.6 acres/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.
Verified means each manufacturer publishes the figure. A bigger number is only a bigger number; nothing here says which machine is better. The full specification table is below.
