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.
- Walker Model C23i has a 74 in (1,880 mm) deck; Walker Model B27ix has a 48 in (1,219 mm) deck, a 26 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 ›
- Walker Model C23i holds 4.7 gal (17.8 L) of fuel; Walker Model B27ix holds 9.4 gal (35.6 L) of fuel, a 4.7 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.
- Walker Model C23i has a published top speed of 8 mph; Walker Model B27ix has a published top speed of 9.6 mph, a 1.6 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Walker Model C23i has a 23 hp engine; Walker Model B27ix has a 26.5 hp engine, a 3.5 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.
- Walker Model C23i cuts from 1.5 in (38 mm) to 4 in (102 mm); Walker Model B27ix cuts from 1.5 in (38 mm) to 4.5 in (114 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.

Calculated by MowerFacts
- Walker Model C23i works out to 4.8 acres/hour; Walker Model B27ix works out to 3.7 acres/hour, a 1.1 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.
