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’s different? The 5 differences that matter most, from the published figures.
- ZG327RPA-60R has a Kubota HST transmission; Z920MZTrak 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.
- ZG327RPA-60R weighs 1,565 lbs (710 kg); Z920MZTrak Zero-Turn Mower weighs 1,313 lbs (595.6 kg), a 252 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZG327RPA-60R's weight means for a trailer ›
- ZG327RPA-60R has a published top speed of 10.6 mph; Z920MZTrak 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.
- ZG327RPA-60R has a 26 hp engine; Z920MZTrak Zero-Turn Mower has a 23.5 hp engine, a 2.5 hp difference. Published horsepower is the maker's rating at a stated engine speed. It is a different measure from displacement, and two engines of equal rating can pull differently.
- ZG327RPA-60R holds 12.7 gal (48.1 L) of fuel; Z920MZTrak Zero-Turn Mower holds 11.5 gal (43.5 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.
