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.
Best suited for
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.
- Husqvarna Z454 — commercial: daily paid use and high acreage; 54-inch deck; gas powered
- Altoz XE 540 — commercial: daily paid use and high acreage; 54-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- Z454 holds 6 gal (22.7 L) of fuel; XE 540 holds 10 gal (37.9 L) of fuel, a 4 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.
- Z454 has a Steel deck; XE 540 has a Fabricated Steel deck.
- Z454 weighs 745 lbs (337.9 kg); XE 540 weighs 930 lbs (421.8 kg), a 185 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Z454's weight means for a trailer ›
- Z454 has a 22 hp engine; XE 540 has a 24 hp engine, a 2 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.
- Z454 has a published top speed of 10 mph; XE 540 has a published top speed of 9 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.

- Z454 cuts from 1.5 in (38 mm) to 4.5 in (114 mm); XE 540 cuts from 1.5 in (38 mm) to 4.3 in (108 mm).
Calculated by MowerFacts
- Z454 works out to 4.4 acres/hour; XE 540 works out to 3.9 acres/hour, a 0.4 acres/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.
