What’s different? The 5 differences that matter most, from the published figures.
- Z572XS has a 38.5 hp engine; Z994R DieselZTrak Zero-Turn Mower has a 24.7 hp engine, a 13.8 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.
- Z572XS weighs 616.4 kg (1,359 lbs); Z994R DieselZTrak Zero-Turn Mower weighs 821 kg (1,810 lbs), a 204.6 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Z572XS's weight means for a trailer ›
- Z572XS has a 999 cc (61 ci) engine; Z994R DieselZTrak Zero-Turn Mower has a 1,266.7 cc (77.3 ci) engine, a 267.7 cc difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- Z572XS has a published top speed of 12 mph; Z994R DieselZTrak Zero-Turn Mower has a published top speed of 11.4 mph, a 0.6 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Z572XS holds 45.4 L (12 gal) of fuel; Z994R DieselZTrak Zero-Turn Mower holds 43.5 L (11.5 gal) of fuel, a 1.9 L 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.
