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.

What’s different? The 3 differences that matter most, from the published figures.
- TSX 561 i holds 8.5 gal (32.2 L) of fuel; TRX 561 i holds 14 gal (53 L) of fuel, a 5.5 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.
- TSX 561 i cuts from 2.5 in (64 mm) to 5.5 in (140 mm); TRX 561 i cuts from 3 in (76 mm) to 7 in (178 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- TSX 561 i has a published top speed of 10 mph; TRX 561 i 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.
calculated figures
Calculated by MowerFacts
- TSX 561 i works out to 4.9 acres/hour; TRX 561 i works out to 4.4 acres/hour, a 0.5 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.
Verified means each manufacturer publishes the figure. A bigger number is only a bigger number; nothing here says which machine is better. The full specification table is below.
