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.
- RIDGELINE 32 lists at $6,499; PRO-STANCE 32 KAWASAKI lists at $9,349, a $2,850 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- RIDGELINE 32 has Hydro-Gear® ZT-2800® Transaxles drive; PRO-STANCE 32 KAWASAKI has Hydro-Gear® ZT-3100® Transaxles drive.
- RIDGELINE 32 holds 4.5 gal (17 L) of fuel; PRO-STANCE 32 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.
- RIDGELINE 32 cuts from 2 in (51 mm) to 4.5 in (114 mm); PRO-STANCE 32 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.
- RIDGELINE 32 has a published top speed of 7 mph; PRO-STANCE 32 KAWASAKI has a published top speed of 8 mph, a 1 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
