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 T27i uses a Rehlko engine; PRO-STANCE 52 KAWASAKI EFI 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 T27i holds 4.7 gal (17.8 L) of fuel; PRO-STANCE 52 KAWASAKI EFI holds 9 gal (34.1 L) of fuel, a 4.3 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 T27i has a published top speed of 7 mph; PRO-STANCE 52 KAWASAKI EFI has a published top speed of 9 mph, a 2 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 T27i cuts from 1.5 in (38 mm) to 4 in (102 mm); PRO-STANCE 52 KAWASAKI EFI 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.
- Walker Model T27i weighs 815 lbs (369.7 kg); PRO-STANCE 52 KAWASAKI EFI weighs 912 lbs (413.7 kg), a 97 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Walker Model T27i's weight means for a trailer ›
