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.
- Dixie Chopper XCaliber 66 in (3566KW) — commercial: daily paid use and high acreage; 66-inch deck; gas powered
- Grasshopper 440 EFI — 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.
- XCaliber 66 in (3566KW) uses a Kawasaki® FX engine; 440 EFI uses a Vanguard 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.
- XCaliber 66 in (3566KW) has a 35 hp engine; 440 EFI has a 40 hp engine, a 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.
- XCaliber 66 in (3566KW) has a 66 in (1,676 mm) deck; 440 EFI has a 61 in (1,549 mm) deck, a 5 in difference. Deck width sets how much grass each pass covers. Mowing time also depends on ground speed, turns and obstacles, so a wider deck alone does not fix the job's length. Time both decks on your own lawn ›
