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.
- XP 610 RDI has a Rear Discharge (RDi) deck; TRX 561 i has a Fabricated Steel All-Terrain Deck or Aero Deck deck.
- XP 610 RDI has 3 blades; TRX 561 i has 6 blades.
- XP 610 RDI has a published top speed of 11 mph; TRX 561 i 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.
- XP 610 RDI weighs 1,360 lbs (616.9 kg); TRX 561 i weighs 1,540 lbs (698.5 kg), a 180 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What XP 610 RDI's weight means for a trailer ›
- XP 610 RDI cuts from 1.5 in (38 mm) to 5 in (127 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.
calculated figures
Calculated by MowerFacts
- XP 610 RDI works out to 5.4 acres/hour; TRX 561 i works out to 4.4 acres/hour, a 1.0 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.
