What’s different? The 5 differences that matter most, from the published figures.
- Automower 435X AWD NERA with wire free technology is rated for 1.24 acres (5,000 m²) of lawn; Automower 305 is rated for 0.15 acres (600 m²) of lawn, a 1.09 acres difference. The rated lawn area is the maker's figure under its own test conditions. Obstacles, slopes and complex shapes reduce it.
- Automower 435X AWD NERA with wire free technology ships with a 8 Ah battery; Automower 305 ships with a 2.1 Ah battery, a 5.9 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 435X AWD NERA with wire free technology weighs 40 lbs (18.1 kg); Automower 305 weighs 21 lbs (9.4 kg), a 19 lbs difference. Operating weight bears on trailer payload, ramps and soft turf.

- Automower 435X AWD NERA with wire free technology runs 145 min per charge; Automower 305 runs 60 min per charge, a 85 min difference. Stated run time is under the maker's conditions. Thick or wet grass shortens it.
- Automower 435X AWD NERA with wire free technology is rated for slopes to 70%; Automower 305 is rated for slopes to 40%, a 30 points difference. The slope rating is the maker's limit for safe operation, not a measure of performance.
