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.
- Walker Model T23 uses a Rehlko engine; Z-STANCE 52 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 T23 weighs 820 lbs (371.9 kg); Z-STANCE 52 KAWASAKI weighs 763 lbs (346.1 kg), a 57 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Walker Model T23's weight means for a trailer ›
- Walker Model T23 has a published top speed of 6.5 mph; Z-STANCE 52 KAWASAKI has a published top speed of 7 mph, a 0.5 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 T23 has a 41.1 ci (674 cc) engine; Z-STANCE 52 KAWASAKI has a 44.3 ci (726 cc) engine, a 3.2 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- Walker Model T23 holds 4.7 gal (17.8 L) of fuel; Z-STANCE 52 KAWASAKI holds 4.5 gal (17 L) of fuel, a 0.2 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.
