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 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.
- Kubota ZG222 — commercial: daily paid use and high acreage; 48-inch deck; gas powered

What’s different? The 5 differences that matter most, from the published figures.
- ZG222 uses a Kubota KGZ770-E2-MA3 engine; SRS Z1 Stand-On Mowers (48 in / 5901940) uses a Kawasaki® FX691V 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.
- ZG222 weighs 1,166 lbs (529 kg); SRS Z1 Stand-On Mowers (48 in / 5901940) weighs 866 lbs (392.8 kg), a 300 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZG222's weight means for a trailer ›
- ZG222 holds 7.1 gal (26.9 L) of fuel; SRS Z1 Stand-On Mowers (48 in / 5901940) holds 6 gal (22.7 L) of fuel, a 1.1 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.
- ZG222 has a published top speed of 9 mph; SRS Z1 Stand-On Mowers (48 in / 5901940) has a published top speed of 8 mph, a 1 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- ZG222 has a 46.9 ci (768 cc) engine; SRS Z1 Stand-On Mowers (48 in / 5901940) has a 44.3 ci (726 cc) engine, a 2.6 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
