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 SO34.5KW — commercial: daily paid use and high acreage; 61-inch deck; gas powered
- Altoz XP 610 SSi — commercial: daily paid use and high acreage; 61-inch deck; gas powered
What’s different? The 2 differences that matter most, from the published figures.
- SO34.5KW has a T6 Drive Transmission transmission; XP 610 SSi has a Hydrostatic transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- SO34.5KW holds 13.5 gal (51.1 L) of fuel; XP 610 SSi holds 14 gal (53 L) of fuel, a 0.5 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.
