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 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.

- Sunseeker Sunseeker X4 — 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 315 Mark II ships with a 2.1 Ah battery; Sunseeker X4 ships with a 5 Ah battery, a 2.9 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 315 Mark II weighs 21 lbs (9.4 kg); Sunseeker X4 weighs 27 lbs (12.2 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 315 Mark II's weight means for a trailer ›
- Automower 315 Mark II is rated for 0.37 acres (1,500 m²) of lawn; Sunseeker X4 is rated for 0.30 acres (1,214 m²) of lawn, a 0.07 acres difference. The rated lawn area is the maker's figure under its own test conditions. Obstacles, slopes and complex shapes reduce it.
- Automower 315 Mark II has a 8.7 in (220 mm) deck; Sunseeker X4 has a 7.9 in (201 mm) deck, a 0.7 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 315 Mark II is rated for slopes to 40%; Sunseeker X4 is rated for slopes to 45%, a 5 points difference. The slope rating is the maker's limit for safe operation, not a measure of performance.
