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.
- Grasshopper 940 EFI — commercial: daily paid use and high acreage; 61-inch deck; gas powered
- Bad Boy Mowers Rebel X — commercial: daily paid use and high acreage; 61-inch deck; gas powered
What’s different? The 3 differences that matter most, from the published figures.
- 940 EFI uses a Vanguard engine; Rebel X 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.
- 940 EFI has a G3 Hydrostatic Transmission transmission; Rebel X has a 5400 Hydro-Gear® 16cc Integrated Transaxle transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- 940 EFI holds 14.4 gal (54.5 L) of fuel; Rebel X holds 13 gal (49.2 L) of fuel, a 1.4 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.
