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 Rival — commercial: daily paid use and high acreage; 60-inch deck; battery (no fuel or engine maintenance)
- Gravely PRO-STANCE EV 52 REAR DISCHARGE — commercial: daily paid use and high acreage; 52-inch deck; battery (no fuel or engine maintenance)
What’s different? The 5 differences that matter most, from the published figures.
- Rival has a Aluminum deck; PRO-STANCE EV 52 REAR DISCHARGE has a 7 ga deck.
- Rival has a 60 in (1,524 mm) deck; PRO-STANCE EV 52 REAR DISCHARGE has a 52 in (1,321 mm) deck, a 8 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 ›
- Rival runs on a 48 V battery; PRO-STANCE EV 52 REAR DISCHARGE runs on a 56 V battery, a 8 V difference. Battery voltage names the platform. Run time depends on the pack's capacity in amp-hours and on the cutting load.
- Rival weighs 1,179 lbs (535 kg); PRO-STANCE EV 52 REAR DISCHARGE weighs 1,236 lbs (560.6 kg), a 57 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Rival's weight means for a trailer ›
- Rival has a published top speed of 11.5 mph; PRO-STANCE EV 52 REAR DISCHARGE has a published top speed of 11 mph, a 0.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
