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.
- ZD1211R-60R has a Kubota HST transmission; Z930MZTrak Zero-Turn Mower has a Hydrostatic transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- ZD1211R-60R runs on Diesel; Z930MZTrak Zero-Turn Mower runs on Gasoline. Fuel type sets what you buy and store; it is not a measure of power.
- ZD1211R-60R has a 68.5 ci (1,123 cc) engine; Z930MZTrak Zero-Turn Mower has a 52 ci (852 cc) engine, a 16.5 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- ZD1211R-60R weighs 1,687 lbs (765 kg); Z930MZTrak Zero-Turn Mower weighs 1,382 lbs (627 kg), a 304 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZD1211R-60R's weight means for a trailer ›
- ZD1211R-60R has a published top speed of 10.6 mph; Z930MZTrak Zero-Turn Mower has a published top speed of 12 mph, a 1.4 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
