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.
Best suited for
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.
- PRO-WALK 52 KAWASAKI lists at $8,499; RIDGELINE 52 lists at $6,799, a $1,700 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- PRO-WALK 52 KAWASAKI has a 18.5 hp engine; RIDGELINE 52 has a 22 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.
- PRO-WALK 52 KAWASAKI holds 5.8 gal (22 L) of fuel; RIDGELINE 52 holds 4.5 gal (17 L) of fuel, a 1.3 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.
- PRO-WALK 52 KAWASAKI has a 36.8 ci (603 cc) engine; RIDGELINE 52 has a 44.3 ci (725.9 cc) engine, a 7.5 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- PRO-WALK 52 KAWASAKI has a published top speed of 8 mph; RIDGELINE 52 has a published top speed of 7 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.
