Prices are the recommended retail prices published by each manufacturer’s Australian site, in AUD, as read on the date shown on each model’s page; dealers set the final price.
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.

- John Deere Z994R DieselZTrak Zero-Turn Mower — commercial: daily paid use and high acreage; 72-inch deck
What’s different? The 5 differences that matter most, from the published figures.
- F2890 holds 61 L (16.1 gal) of fuel; Z994R DieselZTrak Zero-Turn Mower holds 43.5 L (11.5 gal) of fuel, a 17.5 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.
- F2890 has a 28 hp engine; Z994R DieselZTrak Zero-Turn Mower has a 24.7 hp engine, a 3.3 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.
- F2890 weighs 748 kg (1,649 lbs); Z994R DieselZTrak Zero-Turn Mower weighs 821 kg (1,810 lbs), a 73 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What F2890's weight means for a trailer ›
- F2890 has a 1,123 cc (68.5 ci) engine; Z994R DieselZTrak Zero-Turn Mower has a 1,266.7 cc (77.3 ci) engine, a 143.7 cc difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- F2890 has a published top speed of 12.4 mph; Z994R DieselZTrak Zero-Turn Mower has a published top speed of 11.4 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.
