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 B27ix uses a Rehlko engine; Z-STANCE 48 KAWASAKI uses a Kawasaki® engine. The engine maker builds the engine; the mower maker chooses the model, rating and fit, so the badge alone does not settle output or longevity.
- Walker Model B27ix holds 9.4 gal (35.6 L) of fuel; Z-STANCE 48 KAWASAKI holds 4.5 gal (17 L) of fuel, a 4.9 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 B27ix has a published top speed of 9.6 mph; Z-STANCE 48 KAWASAKI has a published top speed of 7 mph, a 2.6 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 B27ix has a 26.5 hp engine; Z-STANCE 48 KAWASAKI has a 22 hp engine, a 4.5 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 B27ix cuts from 1.5 in (38 mm) to 4.5 in (114 mm); Z-STANCE 48 KAWASAKI cuts from 1.5 in (38 mm) to 5 in (127 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
