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 400D — commercial: daily paid use and high acreage; 61-inch deck
- Scag Cheetah II — 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.
- 400D uses a Kubota engine; Cheetah II uses a Vanguard BIG BLOCK 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.
- 400D lists at $20,460; Cheetah II lists at $13,999 to $18,999, a $6,461 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- 400D holds 12 gal (45.4 L) of fuel; Cheetah II holds 13 gal (49.2 L) of fuel, a 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.
