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 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 5 differences that matter most, from the published figures.
- XR 480 / 540 / 540 SS holds 5 gal (18.9 L) of fuel; TFX 766 i holds 14 gal (53 L) of fuel, a 9 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.
- XR 480 / 540 / 540 SS has a 23 hp engine; TFX 766 i has a 38.5 hp engine, a 15.5 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.
- XR 480 / 540 / 540 SS has a 48 in (1,219 mm) deck; TFX 766 i has a 66 in (1,676 mm) deck, a 18 in difference. Deck width sets how much grass each pass covers. Mowing time also depends on ground speed, turns and obstacles, so a wider deck alone does not fix the job's length. Time both decks on your own lawn ›
- XR 480 / 540 / 540 SS has a published top speed of 8 mph; TFX 766 i 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.
- XR 480 / 540 / 540 SS cuts from 1.5 in (38 mm) to 4.3 in (108 mm); TFX 766 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.

- XR 480 / 540 / 540 SS has a 44.3 ci (726 cc) engine; TFX 766 i has a 61 ci (999 cc) engine, a 16.7 ci difference.
