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 X9 Plus is rated for 6.00 acres (24,281 m²) of lawn; Sunseeker X5 is rated for 0.50 acres (2,023 m²) of lawn, a 5.50 acres difference. The rated lawn area is the maker's figure under its own test conditions. Obstacles, slopes and complex shapes reduce it.
- Sunseeker X9 Plus weighs 72 lbs (32.7 kg); Sunseeker X5 weighs 26 lbs (12 kg), a 46 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Sunseeker X9 Plus's weight means for a trailer ›
- Sunseeker X9 Plus has a 17 in (432 mm) deck; Sunseeker X5 has a 8.7 in (221 mm) deck, a 8.3 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 X9 Plus is rated for slopes to 90%; Sunseeker X5 is rated for slopes to 60%, a 30 points difference. The slope rating is the maker's limit for safe operation, not a measure of performance.
- Sunseeker X9 Plus cuts from 0.8 in (20 mm) to 4 in (102 mm); Sunseeker X5 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.
