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’s different? The 5 differences that matter most, from the published figures.
- TRX 354 has a published top speed of 8 mph; Z454XS has a published top speed of 11 mph, a 3 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- TRX 354 has a Fabricated Steel Aero Deck deck; Z454XS has a Steel deck.
- TRX 354 weighs 1,220 lbs (553.4 kg); Z454XS weighs 961 lbs (435.9 kg), a 259 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What TRX 354's weight means for a trailer ›
- TRX 354 holds 10 gal (37.9 L) of fuel; Z454XS holds 12 gal (45.4 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.
- TRX 354 cuts from 2.2 in (57 mm) to 5 in (127 mm); Z454XS cuts from 1.5 in (38 mm) to 4.5 in (114 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
