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.

What’s different? The 5 differences that matter most, from the published figures.
- SILENO minimo, 500 m² weighs 13 lbs (6.1 kg); Automower 305 weighs 21 lbs (9.4 kg), a 7 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What SILENO minimo, 500 m²'s weight means for a trailer ›
- SILENO minimo, 500 m² has a 6.3 in (160 mm) deck; Automower 305 has a 8.7 in (220 mm) deck, a 2.4 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 ›
- SILENO minimo, 500 m² is rated for slopes to 25%; Automower 305 is rated for slopes to 40%, a 15 points difference. The slope rating is the maker's limit for safe operation, not a measure of performance.
- SILENO minimo, 500 m² is rated for 0.12 acres (500 m²) of lawn; Automower 305 is rated for 0.15 acres (600 m²) of lawn, a 0.02 acres difference. The rated lawn area is the maker's figure under its own test conditions. Obstacles, slopes and complex shapes reduce it.
- SILENO minimo, 500 m² runs 70 min per charge; Automower 305 runs 60 min per charge, a 10 min difference. Stated run time is under the maker's conditions. Thick or wet grass shortens it.
