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 Z781KWiTW-54 — commercial: daily paid use and high acreage; 54-inch deck; gas powered
- Cub Cadet ZTX6 54 — commercial: daily paid use and high acreage; 54-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- Z781KWiTW-54 holds 11.6 gal (43.9 L) of fuel; ZTX6 54 holds 5.5 gal (20.8 L) of fuel, a 6.1 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.
- Z781KWiTW-54 has a Parker HTG14 transmission; ZTX6 54 has a Hydro-Gear ZT 3400 Charged transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- Z781KWiTW-54 has Belt drive; ZTX6 54 has Hydrostatic drive.
- Z781KWiTW-54 has a published top speed of 11.2 mph; ZTX6 54 has a published top speed of 9 mph, a 2.2 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Z781KWiTW-54 has a 29.5 hp engine; ZTX6 54 has a 25.5 hp engine, a 4 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.
