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 3 differences that matter most, from the published figures.
- HD PRO 60 KAWASAKI FT has Hydro-Gear® ZT-3200 Transaxles drive; Z422KWTNC-60 has Belt drive.
- HD PRO 60 KAWASAKI FT holds 5.1 gal (19.3 L) of fuel; Z422KWTNC-60 holds 6.8 gal (25.7 L) of fuel, a 1.7 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.
- HD PRO 60 KAWASAKI FT has a published top speed of 8 mph; Z422KWTNC-60 has a published top speed of 10 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.
