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 561 i has a published top speed of 9 mph; ZXL 61 FX820 has a published top speed of 12.5 mph, a 3.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- TRX 561 i has a Fabricated Steel All-Terrain Deck or Aero Deck deck; ZXL 61 FX820 has a 7 Gauge deck.
- TRX 561 i has 6 blades; ZXL 61 FX820 has 3 blades.
- TRX 561 i has a 29.5 hp engine; ZXL 61 FX820 has a 34.5 hp engine, a 5 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.
- TRX 561 i weighs 1,540 lbs (698.5 kg); ZXL 61 FX820 weighs 1,310 lbs (594.2 kg), a 230 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What TRX 561 i's weight means for a trailer ›
