Compare Mowers
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.
- PRO-WALK 48 KAWASAKI uses a Kawasaki® engine; Walker Model C19i uses a Rehlko 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.
- PRO-WALK 48 KAWASAKI holds 5.8 gal (22 L) of fuel; Walker Model C19i holds 4 gal (15.1 L) of fuel, a 1.8 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.
- PRO-WALK 48 KAWASAKI has a published top speed of 8 mph; Walker Model C19i has a published top speed of 6.5 mph, a 1.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- PRO-WALK 48 KAWASAKI has a 36.8 ci (603 cc) engine; Walker Model C19i has a 42.4 ci (694 cc) engine, a 5.6 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- PRO-WALK 48 KAWASAKI cuts from 1.5 in (38 mm) to 5 in (127 mm); Walker Model C19i cuts from 1 in (25 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.
