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.
- Walker Model R22x uses a Kohler engine; Walker Model B23 uses a Rehlko 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.
- Walker Model R22x has a 54 in (1,372 mm) deck; Walker Model B23 has a 74 in (1,880 mm) deck, a 20 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 ›
- Walker Model R22x holds 3 gal (11.4 L) of fuel; Walker Model B23 holds 4.7 gal (17.8 L) of fuel, a 1.7 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.
- Walker Model R22x weighs 703 lbs (318.9 kg); Walker Model B23 weighs 600 lbs (272.2 kg), a 103 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Walker Model R22x's weight means for a trailer ›
- Walker Model R22x has a 45.6 ci (747 cc) engine; Walker Model B23 has a 41.1 ci (674 cc) engine, a 4.5 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.

Calculated by MowerFacts
- Walker Model R22x works out to 3.5 acres/hour; Walker Model B23 works out to 4.8 acres/hour, a 1.3 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.
