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.
- Husqvarna Automower 520 — residential: typical home lawns; 9-inch deck; battery (no fuel or engine maintenance)
- Kress Kress RTKⁿ ½-acre robotic lawn mower — residential: typical home lawns; 8-inch deck; battery (no fuel or engine maintenance)
What’s different? The 5 differences that matter most, from the published figures.
- Automower 520 has a 9.4 in (240 mm) deck; Kress RTKⁿ ½-acre robotic lawn mower has a 7.9 in (200 mm) deck, a 1.6 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 ›
- Automower 520 is rated for 0.59 acres (2,400 m²) of lawn; Kress RTKⁿ ½-acre robotic lawn mower is rated for 0.50 acres (2,023 m²) of lawn, a 0.09 acres difference. The rated lawn area is the maker's figure under its own test conditions. Obstacles, slopes and complex shapes reduce it.
- Automower 520 ships with a 5 Ah battery; Kress RTKⁿ ½-acre robotic lawn mower ships with a 4 Ah battery, a 1 Ah difference. Amp-hours is stored energy at the pack's voltage. Run time also depends on load, so a bigger pack lasts longer under the same conditions, not a fixed time.
- Automower 520 is rated for slopes to 45%; Kress RTKⁿ ½-acre robotic lawn mower is rated for slopes to 40%, a 5 points difference. The slope rating is the maker's limit for safe operation, not a measure of performance.
- Automower 520 weighs 29 lbs (13.3 kg); Kress RTKⁿ ½-acre robotic lawn mower weighs 26 lbs (12 kg), a 3 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Automower 520's weight means for a trailer ›
