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.

  • Ariens RIDGELINE 48 — commercial: daily paid use and high acreage; 48-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
  1. Walker Model B27ix uses a Rehlko 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.
  2. Walker Model B27ix holds 9.4 gal (35.6 L) of fuel; RIDGELINE 48 holds 4.5 gal (17 L) of fuel, a 4.9 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.
  3. Walker Model B27ix has a published top speed of 9.6 mph; RIDGELINE 48 has a published top speed of 7 mph, a 2.6 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
  4. Walker Model B27ix has a 26.5 hp engine; RIDGELINE 48 has a 22 hp engine, a 4.5 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.
  5. Walker Model B27ix has a 45.6 ci (747 cc) engine; RIDGELINE 48 has a 44.3 ci (725.9 cc) engine, a 1.3 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
