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 Z572XS — commercial: daily paid use and high acreage; 72-inch deck; gas powered
- John Deere Z998R DieselZTrak Zero-Turn Mower — commercial: daily paid use and high acreage; 100-inch deck
What’s different? The 5 differences that matter most, from the published figures.
- Z572XS weighs 1,359 lbs (616.4 kg); Z998R DieselZTrak Zero-Turn Mower weighs 2,925 lbs (1,326.8 kg), a 1,566 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Z572XS's weight means for a trailer ›
- Z572XS has a 72 in (1,830 mm) deck; Z998R DieselZTrak Zero-Turn Mower has a 100 in (2,540 mm) deck, a 28 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 ›
- Z572XS has a 61 ci (999 cc) engine; Z998R DieselZTrak Zero-Turn Mower has a 95.7 ci (1,568 cc) engine, a 34.7 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- Z572XS has a 38.5 hp engine; Z998R DieselZTrak Zero-Turn Mower has a 43.4 hp engine, a 4.9 hp difference. Published horsepower is the maker's rating at a stated engine speed. It is a different measure from displacement, and two engines of equal rating can pull differently.
- Z572XS has a published top speed of 12 mph; Z998R DieselZTrak Zero-Turn Mower has a published top speed of 11.5 mph, a 0.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
