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.
- Husqvarna Z554X — commercial: daily paid use and high acreage; 54-inch deck; gas powered
- Exmark Vertex X-Series (52 in) — commercial: daily paid use and high acreage; 52-inch deck; gas powered
What’s different? The 4 differences that matter most, from the published figures.
- Z554X has a 31 hp engine; Vertex X-Series (52 in) has a 35 hp engine, a 4 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.
- Z554X holds 12 gal (45.4 L) of fuel; Vertex X-Series (52 in) holds 14 gal (53 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.
- Z554X cuts from 1 in (25 mm) to 5 in (127 mm); Vertex X-Series (52 in) cuts from 1.5 in (38 mm) to 5 in (127 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- Z554X has a 54 in (1,372 mm) deck; Vertex X-Series (52 in) has a 52 in (1,321 mm) deck, a 2 in difference. Deck width sets how much grass each pass covers. Mowing time also depends on ground speed, turns and obstacles, so a wider deck alone does not fix the job's length. Time both decks on your own lawn ›
