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.

  • Cub Cadet PRO X 660 EFI — commercial: daily paid use and high acreage; 60-inch deck; gas powered
  • Husqvarna Z560L — commercial: daily paid use and high acreage; 60-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
  1. PRO X 660 EFI holds 7.5 gal (28.4 L) of fuel; Z560L holds 12 gal (45.4 L) of fuel, a 4.5 gal difference. Tank size bounds how long a machine runs between stops. Consumption varies with engine, load and speed, so hours per tank are not fixed.
  2. PRO X 660 EFI has a 10-gauge steel deck; Z560L has a Steel deck.
  3. PRO X 660 EFI has a 34.5 hp engine; Z560L has a 27 hp engine, a 7.5 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.
  4. PRO X 660 EFI has a published top speed of 10 mph; Z560L has a published top speed of 12 mph, a 2 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
  5. PRO X 660 EFI lists at $12,799; Z560L lists at $14,399, a $1,600 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
