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.
Best suited for
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.
- Husqvarna W520 — commercial: daily paid use and high acreage; 20-inch deck; gas powered
- Exmark Commercial 30 X-Series (ECX180) — commercial: daily paid use and high acreage; 30-inch deck; gas powered
What’s different? The 4 differences that matter most, from the published figures.
- W520 lists at $1,499; Commercial 30 X-Series (ECX180) lists at $2,699, a $1,200 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- W520 has a 20 in (508 mm) deck; Commercial 30 X-Series (ECX180) has a 30 in (762 mm) deck, a 10 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 ›
- W520 weighs 112 lbs (50.8 kg); Commercial 30 X-Series (ECX180) weighs 185 lbs (83.9 kg), a 73 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What W520's weight means for a trailer ›
- W520 has a published top speed of 3.7 mph; Commercial 30 X-Series (ECX180) has a published top speed of 3.8 mph, a 0.1 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
