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 H38i has a 38 hp engine; Walker Model B27ix has a 26.5 hp engine, a 11.5 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 H38i has a 60 in (1,524 mm) deck; Walker Model B27ix has a 48 in (1,219 mm) deck, a 12 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 H38i has a 61 ci (999 cc) engine; Walker Model B27ix has a 45.6 ci (747 cc) engine, a 15.4 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- Walker Model H38i cuts from 1 in (25 mm) to 5 in (127 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.
- Walker Model H38i weighs 808 lbs (366.5 kg); Walker Model B27ix weighs 720 lbs (326.6 kg), a 88 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Walker Model H38i's weight means for a trailer ›

Calculated by MowerFacts
- Walker Model H38i 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.
