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 H24d weighs 997 lbs (452.2 kg); Walker Model B27i weighs 606 lbs (274.9 kg), a 391 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Walker Model H24d's weight means for a trailer ›
- Walker Model H24d holds 9.4 gal (35.6 L) of fuel; Walker Model B27i holds 4.7 gal (17.8 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 H24d cuts from 1 in (25 mm) to 5 in (127 mm); Walker Model B27i cuts from 1.5 in (38 mm) to 4 in (102 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- Walker Model H24d has a 60 in (1,524 mm) deck; Walker Model B27i has a 74 in (1,880 mm) deck, a 14 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 H24d has a 62.7 ci (1,028 cc) engine; Walker Model B27i has a 45.6 ci (747 cc) engine, a 17.1 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
