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.
- Exmark Radius E-Series (RDE 54 in) — commercial: daily paid use and high acreage; 54-inch deck; gas powered
- Altoz TRX 354 — commercial: daily paid use and high acreage; 54-inch deck; gas powered
What’s different? The 3 differences that matter most, from the published figures.
- Radius E-Series (RDE 54 in) holds 7 gal (26.5 L) of fuel; TRX 354 holds 10 gal (37.9 L) of fuel, a 3 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.
- Radius E-Series (RDE 54 in) cuts from 1.5 in (38 mm) to 5 in (127 mm); TRX 354 cuts from 2.2 in (57 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.
- Radius E-Series (RDE 54 in) has a 23 hp engine; TRX 354 has a 24 hp engine, a 1 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.
