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.

- Z421KWTNC-60 has a published top speed of 10 mph; Z735EZTrak Zero Turn Mower has a published top speed of 8 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.
- Z421KWTNC-60 holds 6.8 gal (25.7 L) of fuel; Z735EZTrak Zero Turn Mower holds 8 gal (30.2 L) of fuel, a 1.2 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.
- Z421KWTNC-60 weighs 904 lbs (410.1 kg); Z735EZTrak Zero Turn Mower weighs 990 lbs (449.1 kg), a 86 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Z421KWTNC-60's weight means for a trailer ›
- Z421KWTNC-60 has a 44.3 ci (726 cc) engine; Z735EZTrak Zero Turn Mower has a 49.4 ci (810 cc) engine, a 5.1 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
