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.

What’s different? The 4 differences that matter most, from the published figures.
- Z920MZTrak Zero-Turn Mower has a Hydrostatic transmission; FasTrak SDX has a Hydro-Gear ZT-3400® transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- Z920MZTrak Zero-Turn Mower weighs 1,313 lbs (595.6 kg); FasTrak SDX weighs 944 lbs (428.2 kg), a 369 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Z920MZTrak Zero-Turn Mower's weight means for a trailer ›
- Z920MZTrak Zero-Turn Mower holds 11.5 gal (43.5 L) of fuel; FasTrak SDX holds 8.5 gal (32.2 L) of fuel, a 3 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.
- Z920MZTrak Zero-Turn Mower has a published top speed of 12 mph; FasTrak SDX 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.
