What’s different? The 5 differences that matter most, from the published figures.
- Automower 540 EPOS is rated for 1.98 acres (8,000 m²) of lawn; Automower 520 EPOS is rated for 1.24 acres (5,000 m²) of lawn, a 0.74 acres difference. The rated lawn area is the maker's figure under its own test conditions. Obstacles, slopes and complex shapes reduce it.
- Automower 540 EPOS weighs 37 lbs (16.7 kg); Automower 520 EPOS weighs 30 lbs (13.8 kg), a 6 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Automower 540 EPOS's weight means for a trailer ›
- Automower 540 EPOS ships with a 4 Ah battery; Automower 520 EPOS ships with a 5 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 540 EPOS has a 10.2 in (260 mm) deck; Automower 520 EPOS has a 9.4 in (240 mm) deck, a 0.8 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 ›
- Automower 540 EPOS runs 85 min per charge; Automower 520 EPOS runs 75 min per charge, a 10 min difference. Stated run time is under the maker's conditions. Thick or wet grass shortens it.
