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 3 differences that matter most, from the published figures.
- PRO-TURN 48 KAWASAKI FX holds 10 gal (37.9 L) of fuel; Z412KWNC-48 holds 6.8 gal (25.7 L) of fuel, a 3.2 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.
- PRO-TURN 48 KAWASAKI FX has a published top speed of 8 mph; Z412KWNC-48 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.
- PRO-TURN 48 KAWASAKI FX weighs 965 lbs (437.7 kg); Z412KWNC-48 weighs 904 lbs (410 kg), a 61 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What PRO-TURN 48 KAWASAKI FX's weight means for a trailer ›
