What’s different? The 5 differences that matter most, from the published figures.
- Walker Model H38i has a 38 hp engine; Walker Model B23 has a 22.5 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.
- Walker Model H38i holds 9.4 gal (35.6 L) of fuel; Walker Model B23 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 H38i cuts from 1 in (25 mm) to 5 in (127 mm); Walker Model B23 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 H38i weighs 808 lbs (366.5 kg); Walker Model B23 weighs 600 lbs (272.2 kg), a 208 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 ›
- Walker Model H38i has a 61 ci (999 cc) engine; Walker Model B23 has a 41.1 ci (674 cc) engine, a 19.8 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
