What’s different? The 4 differences that matter most, from the published figures.
- Automower 305 runs 60 min per charge; Automower 405X runs 50 min per charge, a 10 min difference. Stated run time is under the maker's conditions. Thick or wet grass shortens it.
- Automower 305 ships with a 2.1 Ah battery; Automower 405X ships with a 2 Ah battery, a 0.1 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 305 weighs 21 lbs (9.4 kg); Automower 405X weighs 21 lbs (9.7 kg), a 1 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Automower 305's weight means for a trailer ›
