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 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.

What’s different? The 5 differences that matter most, from the published figures.
- Z454XS has a Steel deck; XE 540 has a Fabricated Steel deck.
- Z454XS has a published top speed of 11 mph; XE 540 has a published top speed of 9 mph, a 2 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Z454XS holds 12 gal (45.4 L) of fuel; XE 540 holds 10 gal (37.9 L) of fuel, a 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.
- Z454XS 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). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- Z454XS weighs 961 lbs (435.9 kg); XE 540 weighs 930 lbs (421.8 kg), a 31 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Z454XS's weight means for a trailer ›
