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 Z242KH-48 — commercial: daily paid use and high acreage; 48-inch deck; gas powered
- Gravely ZT X 48 KAWASAKI — 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.
- Z242KH-48 uses a Kohler KT725 engine; ZT X 48 KAWASAKI uses a Kawasaki® 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.
- Z242KH-48 has Belt drive; ZT X 48 KAWASAKI has Hydro-Gear® Serviceable EZT® Transaxles drive.
- Z242KH-48 holds 4.3 gal (16.3 L) of fuel; ZT X 48 KAWASAKI holds 3.5 gal (13.2 L) of fuel, a 0.8 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.
- Z242KH-48 has a published top speed of 8 mph; ZT X 48 KAWASAKI has a published top speed of 7 mph, a 1 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Z242KH-48 has a 22 hp engine; ZT X 48 KAWASAKI has a 21.5 hp engine, a 0.5 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.
calculated figures and what isn’t comparable
