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.

What’s different? The 5 differences that matter most, from the published figures.
- F60 Zero Turn Mower uses a Kawasaki® FX600V 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.
- F60 Zero Turn Mower holds 8 gal (30.3 L) of fuel; Liberty Z holds 3.5 gal (13.2 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.
- F60 Zero Turn Mower lists at $8,249; Liberty Z lists at $5,599 to $7,399, a $2,650 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- F60 Zero Turn Mower weighs 732 lbs (332 kg); Liberty Z weighs 555 lbs (251.7 kg), a 177 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What F60 Zero Turn Mower's weight means for a trailer ›
- F60 Zero Turn Mower has a 18.5 hp engine; Liberty Z has a 18 hp engine, a 0.5 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.
