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.
- Altoz XC 720 SSi — commercial: daily paid use and high acreage; 72-inch deck; gas powered
- Exmark Vertex X-Series (72 in) — commercial: daily paid use and high acreage; 72-inch deck; gas powered

- XC 720 SSi has a published top speed of 19 mph; Vertex X-Series (72 in) has a published top speed of 12 mph, a 7 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
