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.
- Cutting Width: RIDGELINE 32 32 in (813 mm); RIDGELINE 48 48 in (1,219 mm); RIDGELINE 52 52 in (1,321 mm), a 20 in spread. 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 ›
- Engine Make: RIDGELINE 32 Kawasaki FS600V; RIDGELINE 48 Kawasaki FS651V; RIDGELINE 52 Kawasaki FS651V. 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.
- Engine Power: RIDGELINE 32 18.5 hp; RIDGELINE 48 22 hp; RIDGELINE 52 22 hp, a 3.5 hp spread. 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.
- Displacement: RIDGELINE 32 36.8 ci (603 cc); RIDGELINE 48 44.3 ci (725.9 cc); RIDGELINE 52 44.3 ci (725.9 cc), a 7.5 ci spread. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- Blades: RIDGELINE 32 2 blades; RIDGELINE 48 3 blades; RIDGELINE 52 3 blades.

Calculated by MowerFacts
- Mowing rate: RIDGELINE 32 1.8 acres/hour; RIDGELINE 48 2.7 acres/hour; RIDGELINE 52 2.9 acres/hour, a 1.1 acres/hour spread. 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.
