Compare Mowers
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’s different? The 5 differences that matter most, from the published figures.
- Z254F holds 13.2 L (3.5 gal) of fuel; Z422KW-54 holds 25.7 L (6.8 gal) of fuel, a 12.4 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.
- Z254F has a Hydrostatic transmission; Z422KW-54 has a 2-HST w/Gear reduction transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- Z254F weighs 267.6 kg (590 lbs); Z422KW-54 weighs 400 kg (882 lbs), a 132.4 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Z254F's weight means for a trailer ›
- Z254F has a published top speed of 6.5 mph; Z422KW-54 has a published top speed of 9.9 mph, a 3.4 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Z254F has Collect/Mulch/Side discharge discharge; Z422KW-54 has Side discharge discharge.
