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.

What’s different? The 5 differences that matter most, from the published figures.
  1. Freedom Z uses a Kohler® 7000 Series engine; Liberty Z uses a Kawasaki® FR Series engine. The engine maker builds the engine; the mower maker chooses the model, rating and fit, so the badge alone does not settle output or longevity.
  2. Freedom Z holds 6.5 gal (24.6 L) of fuel; Liberty Z holds 3.5 gal (13.2 L) of fuel, a 3 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.
  3. Freedom Z has a 48 in (1,219 mm) deck; Liberty Z has a 36 in (914 mm) deck, a 12 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 ›
  4. Freedom Z has a 24 hp engine; Liberty Z has a 18 hp engine, a 6 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.
  5. Freedom Z weighs 745 lbs (337.9 kg); Liberty Z weighs 555 lbs (251.7 kg), a 190 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Freedom Z's weight means for a trailer ›

  • Freedom Z lists at $6,899 to $7,799; Liberty Z lists at $5,599 to $7,399, a $1,300 difference.
  • Freedom Z has a published top speed of 8 mph; Liberty Z has a published top speed of 7 mph, a 1 mph difference.

Calculated by MowerFacts

  • Freedom Z works out to 3.1 acres/hour; Liberty Z works out to 2.0 acres/hour, a 1.1 acres/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.

Verified means each manufacturer publishes the figure. A bigger number is only a bigger number; nothing here says which machine is better. The full specification table is below.
