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 52 uses a Kawasaki FS651V engine; Walker Model T23 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.
- RIDGELINE 52 weighs 731 lbs (331.6 kg); Walker Model T23 weighs 820 lbs (371.9 kg), a 89 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What RIDGELINE 52's weight means for a trailer ›
- RIDGELINE 52 has a published top speed of 7 mph; Walker Model T23 has a published top speed of 6.5 mph, a 0.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- RIDGELINE 52 has a 44.3 ci (725.9 cc) engine; Walker Model T23 has a 41.1 ci (674 cc) engine, a 3.2 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- RIDGELINE 52 holds 4.5 gal (17 L) of fuel; Walker Model T23 holds 4.7 gal (17.8 L) of fuel, a 0.2 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.

Other verified differences
- RIDGELINE 52 has a 22 hp engine; Walker Model T23 has a 22.5 hp engine, a 0.5 hp difference.

- RIDGELINE 52 works out to 2.9 acres/hour; Walker Model T23 works out to 2.7 acres/hour, a 0.2 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.
