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.
- Mean Green Nemesis — commercial: daily paid use and high acreage; 60-inch deck; battery (no fuel or engine maintenance)
- Gravely PRO-STANCE EV 60 REAR DISCHARGE — commercial: daily paid use and high acreage; 60-inch deck; battery (no fuel or engine maintenance)
What’s different? The 2 differences that matter most, from the published figures.
- Nemesis has a published top speed of 8 mph; PRO-STANCE EV 60 REAR DISCHARGE has a published top speed of 11 mph, a 3 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Nemesis has a Aluminum deck; PRO-STANCE EV 60 REAR DISCHARGE has a 7 ga deck.
