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 each model is built for, from its duty class and key specs. This is a neutral reference — MowerFacts does not rank one model above another.

What’s different? The 5 differences that matter most, from the published figures.
- Z-STANCE 52 KAWASAKI has a 52 in (1,321 mm) deck; PRO-STANCE 36 KAWASAKI has a 36 in (914 mm) deck, a 16 in difference. Deck width sets how much grass each pass covers. Mowing time also depends on ground speed, turns and obstacles, so a wider deck alone does not fix the job's length. Time both decks on your own lawn ›
- Z-STANCE 52 KAWASAKI has a 10 ga deck; PRO-STANCE 36 KAWASAKI has a 7 ga deck.
- Z-STANCE 52 KAWASAKI holds 4.5 gal (17 L) of fuel; PRO-STANCE 36 KAWASAKI holds 6 gal (22.7 L) of fuel, a 1.5 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.
- Z-STANCE 52 KAWASAKI has a 22 hp engine; PRO-STANCE 36 KAWASAKI has a 18.5 hp engine, a 3.5 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.
- Z-STANCE 52 KAWASAKI lists at $8,399; PRO-STANCE 36 KAWASAKI lists at $9,559, a $1,160 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.

- Z-STANCE 52 KAWASAKI works out to 2.9 acres/hour; PRO-STANCE 36 KAWASAKI works out to 2.3 acres/hour, a 0.6 acres/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.
Verified means each manufacturer publishes the figure. A bigger number is only a bigger number; nothing here says which machine is better. The full specification table is below.
