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.
- Husqvarna MZ 61 ROPS Special Edition — commercial: daily paid use and high acreage; 61-inch deck; gas powered
- Kubota Z421KWTNC-60 — commercial: daily paid use and high acreage; 60-inch deck; gas powered
What’s different? The 4 differences that matter most, from the published figures.
- MZ 61 ROPS Special Edition has a Hydrostatic transmission; Z421KWTNC-60 has a Hydro-Gear Commercial ZT-3600 transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- MZ 61 ROPS Special Edition holds 5 gal (18.9 L) of fuel; Z421KWTNC-60 holds 6.8 gal (25.7 L) of fuel, a 1.8 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.
- MZ 61 ROPS Special Edition has a published top speed of 8.5 mph; Z421KWTNC-60 has a published top speed of 10 mph, a 1.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- MZ 61 ROPS Special Edition weighs 844 lbs (382.8 kg); Z421KWTNC-60 weighs 904 lbs (410.1 kg), a 60 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What MZ 61 ROPS Special Edition's weight means for a trailer ›
calculated figures and what isn’t comparable
