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 2 differences that matter most, from the published figures.
- Walker Model B27i has a 26.5 hp engine; Walker Model B23 has a 22.5 hp engine, a 4 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 B27i has a 45.6 ci (747 cc) engine; Walker Model B23 has a 41.1 ci (674 cc) engine, a 4.5 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
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.
