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’s different? The 5 differences that matter most, from the published figures.
- Sunseeker X7 is rated for 0.75 acres (3,035 m²) of lawn; Sunseeker X4 is rated for 0.30 acres (1,214 m²) of lawn, a 0.45 acres difference. The rated lawn area is the maker's figure under its own test conditions. Obstacles, slopes and complex shapes reduce it.
- Sunseeker X7 has a 14 in (356 mm) deck; Sunseeker X4 has a 7.9 in (201 mm) deck, a 6.1 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 ›
- Sunseeker X7 ships with a 10 Ah battery; Sunseeker X4 ships with a 5 Ah battery, a 5 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.
- Sunseeker X7 is rated for slopes to 70%; Sunseeker X4 is rated for slopes to 45%, a 25 points difference. The slope rating is the maker's limit for safe operation, not a measure of performance.
- Sunseeker X7 cuts from 0.8 in (20 mm) to 4 in (102 mm); Sunseeker X4 cuts from 1.6 in (41 mm) to 3.2 in (81 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
