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; ZXL 61 FX850E has a 7 Gauge deck.
- XP 610 RDI cuts from 1.5 in (38 mm) to 5 in (127 mm); ZXL 61 FX850E cuts from 1.5 in (38 mm) to 6 in (152 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- XP 610 RDI has a published top speed of 11 mph; ZXL 61 FX850E has a published top speed of 12.5 mph, a 1.5 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 has a 29.5 hp engine; ZXL 61 FX850E has a 27 hp engine, a 2.5 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.
- XP 610 RDI holds 14 gal (53 L) of fuel; ZXL 61 FX850E holds 15.5 gal (58.7 L) of fuel, a 1.5 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.
