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 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.
- RIDGELINE 32 uses a Kawasaki FS600V engine; RIDGELINE 48 uses a Kawasaki FS651V 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.
- RIDGELINE 32 has a 32 in (813 mm) deck; RIDGELINE 48 has a 48 in (1,219 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 ›
- RIDGELINE 32 has a 18.5 hp engine; RIDGELINE 48 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.
- RIDGELINE 32 has a 36.8 ci (603 cc) engine; RIDGELINE 48 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.
- RIDGELINE 32 has 2 blades; RIDGELINE 48 has 3 blades.

Calculated by MowerFacts
- RIDGELINE 32 works out to 1.8 acres/hour; RIDGELINE 48 works out to 2.7 acres/hour, a 0.9 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.
